Essays on Glycogen

Introduction

In recent decades, trends in diets tailored to promote weight loss have resulted in a significant increase in the intake of protein, particular in people with overweight and obesity issues. Accordingly, researchers have questioned the benefits or risks linked to the habitual consumption of “dietary protein in excess of recommended intakes” (Martin et al., 2005). In general, the primary concern has involved the possibility that diets rich in protein may increase hyperfiltration and, hence, exacerbate renal damage. Nevertheless, the potential link between protein-rich diets and renal damage has also been questioned due to an absence of adequate clinical evidence. ...

Type 2 diabetes is featured by the conflation of insulin resistance and inappropriate insulin secretion. The levels of free fatty acids increase the plasma contribution to the insulin resistance which, in turn, decreases the transportation of glucose to the muscle cells and enhances the breakdown of the fat. The pathophysiology of the disease is debated on account of the role of insulin sensitivity and beta-cell functioning. Additionally, the specific roles played by these factors are still unclear. Nonetheless, there is considerable agreement that both these factors are crucial to explaining the disease's pathophysiology. Diabetes Type II typically exists when ...

Liver is the largest ‘gland’ of the digestive system. It is located right under the dome of the diaphragm, coated by the capsule. It is distinguished the liver’s convex upper surface adjacent to the diaphragm, and a lower, downwardly facing and in contact with the back and abdominal organs. On the part of the upper surface of the liver it can be seen its right and left lobes, the boundary of which is the crescent liver ligament. To the lower surface of the right lobe there is a gallbladder, close to the deep groove of the liver there ...

The patient presented in this case suffers from metabolic syndrome. The metabolic syndrome is a cluster of health problems that is associated with the presence of obesity and tissues resistance to insulin. The metabolic syndrome is a condition that causes a myriad of problems in the body such that the body becomes incapable of maintaining the circulation of the useful energy molecules such as glucose and lipids in the right quantities in the bloodstream (Huang, 2009). Other associated disorders of metabolic syndrome include high blood pressure and dyslipidemia. The lipid problem is characterized by elevated levels of triglycerides and ...

Abstract

This paper discusses how exercise stimulates the release of growth hormone. Older people tend to have lower levels of the hormone. As a result, mechanisms have been formulated to help deal with the deficiency which includes inducing the growth hormone into the individual’s body. This, therefore, leads to the discussion of the exact mechanism through which the growth hormone facilitates exercise, maintains growth and repair of worn out muscles or even reverses the aging process among the aged. Also, the functions of IGF-I binding proteins during exercise and its importance in aiding the release of the GH is ...

1. Balance Diet and Physical Activity against Obesity and Hypertension The most essential way to prevent hypertension for those who are prone to obesity, and certainly for obese people - is the fight against excess weight. When we reduce the body mass by 1 kilogram - blood pressure decreases by 1 millimeter of mercury regardless of the original pressure level. There are only two ways to lose weight: a diet regime and an increased physical activity. But it is important to immediately warn against fasting that is very dangerous for health. It is possible only under the supervision of ...

The Major Anatomical regions, landmarks, directions and cavities of the liver

The liver is considered as the heart of the digestive system. In humans, the liver is present in the upper right quadrant pf the abdominal cavity. The liver lies below the diaphragm. The gallbladder is covered by the liver to some extent. It is a vital organ that plays an important role in the production of chemicals for digestion in humans. The liver is divided in to two lobes, the left and the right lobe respectively. The two lobes are separated by the imaginary plan called the Cantlie's line. The liver is connected by two large blood vessels, the portal ...

Q. 1. Explain how gel filtration chromatography (size exclusion chromatography) separates molecules on the basis of their mass/size.

A. In gel filtration, porous beads are packed into a column. The pores are of different size. The column is then packed with a buffer solution. This buffer solution is present inside the beads as well as around it. When molecules of different size pass through the columns, the smaller molecules pass through the pores and take a longer path. The larger molecules, however, travel around the beads. Thus, larger molecules travel faster than the ...

General purpose: Persuasive speech

Specific purpose: Why breakfast is the most important meal of the day Introduction: Ladies and gentle how would you feel if the world stops for few hours? Your body stops functioning simply because your ignorance. My husband found the answer to this question in a hard way that he would never try to relive that moment. He had the ritual of waking up late and rush to the office with a packet of four biscuits as his breakfast. However, one day as he was going about his usual busy schedule at the office, he felt weak and fainted. Lucky, ...

Lipids insolubility in water is general. Lipids structure has great number of variety. There are two types of fatty acids naturally, may be saturated or unsaturated. Unsaturated acids have lesser melting point than saturated ones. There are two polyunsaturated fatty acids, linolenic and linoleic, their absence in the human diet has been associated with health problems so they designated essential. Their absence can cause scaly skin, increased dehydration and stunted growth.

Lipids and oxidation of carbohydrates provide all needed energy to the human body. Lipids are primarily energy reserves and carbohydrates are readily available source of energy. Lipids have ...

For building muscle mass and losing body fat, a strict exercise regimen must be followed. In the fitness schedule, two types of activities should be included, namely strength training or anaerobic exercises and cardio or aerobic exercises (Aworkoutroutine.com 1). With respect to strength training, practice an upper/lower split session to allow muscles in the upper and lower body to be trained at regular intervals.

For the upper body muscles, include bench press, incline dumbbell and barbell press, rows, lateral pull-downs and raises and triceps press downs. For the lower body muscles, do deadlifts, leg press, leg curls, squats, abs ...

Energy Storage inform of Lipids

Lipids are a class of natural compounds that are hydrophobic in nature and consist of ketoacyl and isoprene groups. They include sterols, waxes, fats, glycerides, phospholids and fat soluble vitamins such as vitamins A, E and K. Lipids are structural compounds being components of the cell wall but also serve in energy storage and signaling. The signaling function of lipids results from their use in nerve cell axons and as bases for hormones. After digestion and absorption lipids are carried as lipoproteins by blood to the liver which regulates lipid levels in blood. Excess lipids are converted to adipose tissue ...

Influence of Coffee on Exercise

Caffeine is a pharmacologically active substance that is consumed extensively around the world today. Various dietary sources of caffeine include coffee, tea, chocolate, carbonated drinks and energy beverages (Goldstein et al., “International society” 2010). Among these dietary sources, coffee is the most significant and widely consumed source of caffeine around the world in the present times. Statistics from North America and Europe show that around 90% of the adults consider themselves as regular coffee drinkers and their average caffeine intake adds up to approximately 200mg per day (Pesta et al., 2013). Chemically, caffeine is 1, 3, 7,-trimethylxanthine i.e. ...

How Enzymes Act As Protein Catalysts in Biochemical Processes Catalysis refers to the speeding up of a chemical reaction by a catalyst. A catalyst is a substance that accelerates a chemical reaction but does not undergo a permanent chemical change in the process. Enzymes are catalysts whose building blocks are amino acids: they are proteins. Enzymes also exhibit a defined three-dimensional structure. In addition, they have a cleft on their surface called active site. The active site is the region where substrate interactions take place. Enzymes play important roles in fructose metabolism. The first step of fructose metabolism in the liver is the phosphorylation of ...

Von Gierke Disease

Introduction Von Gierke disease or Glycogen Storage Disease Type 1 (GSD-1) belongs to a group of rare metabolic disorders with a reported incidence of 1 case per 100,000 births per year. The clinical condition results from deficiency of key enzymes in the glycolytic pathway resulting in an increase in intermediate metabolites and accumulation of glycogen in the affected tissues. It is a genetic disorder with a natural history of severe developmental abnormalities and long term complications. This paper provides an overview of GSD-1 based on studies published in peer reviewed journals with a focus on its genetic determinants, clinical picture, available therapeutic ...

Introduction

Obesity and overweight have been classified as global and serious conditions that have an adverse effect on the human health. Obesity and overweight conditions are defined as excessive or abnormal accumulation of fat that may negatively affect health. In adults the obesity and overweight are measured by the body mass index (BMI), which is simple weight-for-height index (WHO, 2014). The BMI is computed by the ratio of the individual's body weight to the square of body height, indicated in Kg/m2 (WHO, 2014). According to W.H.O., (World Health Organisation), a BMI equal or above 25 is considered as overweight while a BMI ...

Harvey requires enough energy to perform. Consequently, he must consume enough calories to meet all his energy needs. The actual requirement for calorie intake depends on one’s level of fitness and bodyweight. In addition, the intensity, frequency, and duration of physical activity also greatly influence one’s actual energy requirement.

Carbohydrates

Given that Harvey’s daily workouts involve high-intensity activities, his calorie intake should comprise of between55 to 70 percent carbohydrates. In this case, 3 grams per pound of body weight would be appropriate. Based on this recommendation, Harvey should consume approximately 480 grams of carbohydrates per day in ...

Heart failure is mostly described as a chronicle disease where the heart is unable to pump the blood sufficiently to the body, with other terms like congestive cardiac failure often been used interchangeably. Some of the symptoms are leg swelling, excessive tiredness and breath shortness. Breath shortage is mostly the worse since lying down and sleeping at night is difficult. Most of the common causes that lead to heart failure are blood pressure, atrial fibrillation and valvular heart disease. These causes lead to failure in functioning of the heart structure mainly due to left ventricular and fain normal ejection fraction. ...

It should also comprise of the exact number of calories to attain and sustain a healthy weight, enable the consumer to maintain their Body Mass Index (BMI) and be low in processed foods, cholesterol and excess sugars. Every person is ...

The use of fat in the context of athletics remains one of the most equivocal topics across various parts of the globe. This is because there exists varied opinions on the efficiency of fats in enhancing performance of endurance athletes. Nonetheless, the arguments postulated by those in support and in opposition of the use of fats in athletics are justified in a number of ways. Those in support of the use of high fat diets to enhance the performance of endurance athletes postulate that high fat diets proved a more concentrated form of energy, which is certainly crucial during periods of ...

Biology

The electron microscope has proven to be invaluable in the study of proteins and has enhanced our understanding of cellular biology. The importance to understanding disease and trauma to the body as well as treatments cannot be overstated. Genetic research such as studies of the mechanisms of protein folding is better understood due to electron microscopy. The image of a sample such as a slice of a fibril or a “newly synthesized chain of amino acids” (Dobson, 2003, p. 884) created by an electronic beam. The Transmitting Electron Microscope (TEM) transmits the electron beam through a sample whereas the SEM scans the surface ...

According to Ibim (51) glycogen, which is also known as animal starch refers to a branched polysaccharides stored in the liver or muscle cells of animals after ignition of food excess in starch content. The body converts the extra glucose to glycogen, which react to prevent blood sugar from increasing more than the required level of the body that is 300mg/dl of blood. Therefore, when the body sugar level is low, glycogen is then broken down to glucose as a source of energy in a process known as glycolysis. It is the main energy supplier in the body during exercise when oxygen ...

In the healthcare perspective, according to Gennaro et al. (2000), biochemical reactions are the chemical reactions involved in biochemical and cellular processes and particular actions of substances that affect these processes. Understanding biochemical reactions lead to the “understanding of the molecular bases of diseases”. The knowledge of receptor sites and metabolism (among other things) direct healthcare measures in efficient therapy management. Knowing normal cellular communication and metabolic pattern chemical reactions determine conditions that are abnormal in disease states. To Giese (2013), the scope of pharmaceutical reactions involve those of pharmaceutical biomolecules and biomolecule analogues and the chemical reactions involving ...

(City, State) The Cori cycle, which is also referred to as Lactic acid cycle, is a metabolic pathway where lactate that is produced through anaerobic glycolysis taking in the muscle moves to the liver to be converted into glucose. The glucose produced is then taken back to the muscles to be converted again to lactate. They activities in the muscle get their energy from the breakdown of molecules of glycogen through the glycogenolysis. This process results in the production of a glucose molecule in the glucose-1-phosphate (G-1-P) form. The G-1-P is then converted by the phosphoglocomutase enzyme to G-6-P, which ...

Introduction

A balanced diet refers to the food intake, which incorporates all the dietary needs of an organism in the right proportions. This is unlike the adequate diet, which includes the energy that is sufficient energy for the need of an individual. A balanced diet, therefore, includes both sufficient energy as well as all the dietary requirements that are needed by an individual at the right proportion. The main components that make up a balanced diet include carbohydrate, proteins, vitamins, fats, dietary fiber, water and minerals. Carbohydrates as a source of nutrients in the body are usually broken down through ...

1. What happens to glucose or galactose when the Cu2 in Benedict’s is reduced? The glucose and galactose both monosaccharaides are oxidized. The cyclic structures of both sugars are opened resorting to an aldehyde group at the end of the aliphatic compound. The aldehyde group is the one that reduces benedict’s solution and oxidizes the sugars. 2. Would you expect fructose or glucose to form a red color rapidly with Seliwanoff’s reagent? Fructose is a ketose therefore, a deep red color will form quickly with Seliwanoff reagent, while glucose an aldose with form a light pink color ...

Introduction

Diabetes mellitus is chronic metabolic disorder characterized by elevated blood glucose levels as a result of a dysfunction in the hormonal regulation of blood glucose. The dysfunction of blood glucose regulation occurs due to deficiency of insulin, the resistance of target cells to insulin thus resulting to elevated levels of blood glucose (hyperglycemia). Based on the mechanism resulting in elevated blood sugar there are basically two types of Diabetes: Type I diabetes (insulin-dependent diabetes mellitus (IDDM)) emanates from insufficient insulin due to inability of pancreatic beta cells to produce enough insulin. On the other hand Type II diabetes, (non–insulin-dependent diabetes ...

Fatigue: Processes, Side-effects and the Wingate Bicycle Test

When a person overexerts himself from doing strenuous activities through the say, he may feel sore and tired in each part of his body. This type of problem is called fatigue. Fatigue is mostly connected to the feeling of exhaustion because of the lack of energy and stress because of too much work, lack of sleep, lack of exercise or even because of boredom. But how exactly does this process work and how a person can discern fatigue once it is happening in the body. This paper will discuss the processes on how fatigue takes into place in the body, how ...

Introduction

Glucose- a monosaccharide- is one of the simplest sugars utilized as a primary source of energyat the cellular level. Glucose is essential because some vital organs such as the brain and the red blood cells wholly rely on it as an energy source.

With reference to glucose metabolism, the glycolytic pathway(figure 1) offers the fastest means to energy production. Hence in case of energy deficit the body will break down any available glucose prior to utilizing other sources of energy such as amino acids, pyruvate and glycerol. Glucose is usually preserved in the body as glycogen (polysaccharide) especially in the ...
