Introduction

Water is termed the ‘universal solvent’ since it is capable of dissolving a large variety of substances. These solutes can be broadly classified as ionic and molecular solutes, based on their behaviour in solution. Ionic solutes dissociate into their constituent ions when dissolved in water. An example of this class is sodium chloride (common salt). Molecular solutes are dissolved as uncharged molecules, like sucrose (sugar). The effect of ionic solutes on the boiling point of water is the focus of this project. Boiling occurs when the vapour pressure above a liquid equals the pressure over it. Hence, the normal ...

Introduction Wheat (Triticum sp.), an extensively adapted crop, is one of the primitive and primary staple food crops in the world. Wheat is cultivated from temperate; dry to irrigated or rain-fed areas, to warm, humid or cold conditions. Such a high adaptability is attributed to its intricate genome (Acevedo et al., 2002). Wheat cultivation covers more land area compared to other commercial crops and endures to be an essential food grain for humans (Curtis, 2002). Estimations reveal that by 2050, the population of the world will reach 9.1 billion (34 percent greater than today); correspondingly, the food requirement and ...

Introduction

Dental implants are increasingly becoming popular because a large section of clinicians believe that natural tooth restoration techniques are inferior to dental implants as implants have a longer life than natural tooth and are less susceptible to biological changes. There are various types of dental implants that support crown, bridges, and dentures, and act as orthodontic anchors and facial prosthesis. The basis of the modern dental implant is a biological process in which titanium forms a bond with bone. Dental fixture is first implanted and then a prosthetic is added. Over the years, various implant impression techniques, such as ...

Abstract In this lab, the water quality, contamination, and treatment were investigated. The ability of contaminants (oil, vinegar, and laundry detergent) to remain in the water after passing through the ground was examined. Also, the simple filtering procedure was assessed for its effectivity in purifying water contaminated with soil. The quality of tap water, Fiji, and Dasani bottled waters by the content of ammonia, chlorides, iron, phosphates, total alkalinity, total chlorine, total hardness, and pH was analyzed and compared. All of the studied contaminants proved to remain in the volume of water after passing through the soil; the proposed ...

Stone Formation in the Kidney/ Role of Citrate in the Kidneys

Kidney stones are calcified or solidified molecules taking place in the upper urinary tract and the kidney. Kidney stones are usually composed of calcium as oxalate, phosphate, or carbonate. Stone formation in the kidney happens when the amount of mineral salts in the urine becomes saturated, during which the mineral will automatically crystallize (Rao et al., 2011). Stone formation is further facilitated by increasing amount of calcium in urine and dehydration. High levels of calcium in urine can indicate kidney disorder, prolonged incapacitation, hyperthyroidism or overactive thyroid, excessive intake of milk or aluminum and vitamin D. Stone formation in ...

Based on the initial symptoms, the patient most likely suffers from hypothyroidism or low thyroid hormone disorder. Further clinical tests and an examination of the family’s medical history reveals that the particular disorder could be Hashimoto’s disease; also called Hashimoto thyroiditis. Hashimoto thyroiditis is classified as an autoimmune disease. In autoimmune disease, one's immune system attacks the body’s tissue specifically the thyroid gland (Skugor & Wilder, 2006, p.2). By attacking the thyroid gland, the disease reduces the gland’s ability to produce thyroid hormones of substantial quantity. This condition leads to hypothyroidism. Thyroid hormone deficiency presents with ...

DNA and its importance in our lives

Introduction Deoxyribonucleic acid (DNA) is a long linear polymer located in the nucleus of a cell. It is developed from nucleotides and shaped like a double helix. It is related to the transmission of hereditary information from one generation to the second generation. DNA contains the information for the development as well as reproduction of an organism, thereby leading to a normal life. In the year 1953, James Watson, a biologist, and Francis Crick, a physicist, discovered the structure of DNA in a laboratory in England (LEROY, 2003). The structure of DNA helped scientists to know the process ...

Introduction

There are environmental chemical processes which require light to react. These processes are called photochemical reactions. Photochemical reaction is commonly initiated due to the absorption of solar energy or light. When molecules absorb energy in the form of light, the atoms are converted in a transient excited state (Larson & Weber, 1994). This transition state or excited has completely different physical and chemical properties with the initial state of the molecule. The excited states also have more tendencies to react since they are considered stronger acids and stronger reductants that the initial state of the molecule. The excited state of ...

Water Pollutant - Phosphate

Phosphates are nutrients essential for plant as well as animal growth. But, when their concentration exceeds certain limit they pose serious problems to water bodies, and adversely affect water quality. Major sources of phosphates are non-point sources that include agricultural run-off and sewage or domestic effluent (West Cumbria Rivers Trust, 2015). Phosphate fertilizers used in agriculture are washed off during rains, and they reach nearby water bodies. Sewage receives phosphates from detergents and food or drink additives (West Cumbria Rivers Trust, 2015). Excess phosphates in the water body lead to algal bloom or “eutrophication” that completely destroys the quality ...

Question 1

For succinate oxidation to fumarate there is yield of 2H+ and 2 electrons; however, the process of the reaction skips one step thereby leading to 2 ATP. The resulting FADH2 electrons skips the first stage of oxidative phosphorylation by moving into the electron transport chain located in CoQ. This can be illustrated as NADH -> CoQH2. Consequently, there is 2 ATP forming stages found in the electron chain from CoQ to O2 used in this course (Schwender et al, 50). Indifferent to the first scenario, oxidation of malate to produce oxaloacetate results to NADH, with production of 2H+ and ...

1. The molecule chosen for the analysis is Immunicillin -H. It is a transition state analogue for the enzyme purine nucleoside phosphorylase (PNP). Chemically Immunicillin -H is [(1S)-1-(9-deazahypozanthine-9yl)-1,4-dideoxy-1,4-imino-D-ribitol] (Kicska et al. 2001) 2. PNP is important for the degradation of nucleotides, especially deoxy guanosine. In the absence of this enzyme, deoxy guanosine accumulates and inhibits T cell function, causing T cell mediated immunosuppression. Inhibitors of PNP were found useful in treating T cell malignancies. Inhibiting PNP using transition state analogue, triggers apoptosis of T cells. Though Immunicillin-H inhibits stimulated malignant and nonmalignant T cells, ...

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 ...

- Explain how enzymes are involved in processes such as the breakdown of fructose Enzymes are organic catalysts. In this context, organic denotes the matter in question is generated or is obtained from a living life form. The word Catalyst indicates a matter that has the aptitude to boost a chemical reaction’s rate, and is neither transformed nor damaged by the reaction that it speeds up.

Many chemical reactions occur but a slow rate that their progress would seem to be imperceptible at normally encountered environmental temperature. However, the enzymes are specific to certain functions. Generally, they may speed up a reaction, ...

Introduction

Capsular polysaccharides are of high molecular mass and low molecular weight cell-surface polysaccharides of Gram-positive and Gram-negative bacteria (Wang et al. 2000). They facilitate evading the immune system; therefore, the production and extraction of this layer is a prospective therapeutic target (rcsb.org). In the Gram-positive bacterium Streptococcus pneumoniae, strain TIGR4 the Cps4B is tyrosine protein phosphatase CpsB. The phosphatases have capability to dephosphorylate their analogous autokinases, instead of their similar functionality equivalence; they don’t demonstrate sequence homology. This capsule or CPS act as an interface border between a microbe and its environment that presents an expansive biological and clinical significance. ...

- Describe two features that make all enzymes catalysts.

Enzymes are catalysts that increase the rate of reaction between substances and remain unchanged in the reaction. Enzymes are vital to several bodily functions and make possible such processes like metabolism and catabolism. Two features that make enzymes catalysts is their ability to lower the activation energy and their inherent tendency to combine with coenzymes and cofactors. Activation energy is the minimum energy required to activate the molecules of reactants in order to initiate a chemical reaction. Some substrates have high activation energies that would need very high temperatures to activate ...

Minerals are classified by their chemical composition as Silicates, Phosphorites, carbonates, and halides are all major mineral groups.

Silicates contain silicon (Si) and oxygen (O), the two most abundant elements in the earth and comprise the majority of Earth's crust. They have a chemical formula SiO2. Common silicate minerals include olivine, pyroxene, amphibole, mica and quartz.

Phosphorites are sedimentary rocks of biochemical origin and are rich in phosphate with chemical formula PO4. They are mostly used as chemical fertilizers. They are also used as food preservatives, anti-corrosion agent and also in the field of metallurgy. Limestone and mudstone are common phosphate bearing rocks.Carbonates are the minerals mostly found in the Earth’s near surface crust. They have ...

1) Proto-Oncogenes and Tumor Suppressor Genes are two types of genes that ordinarily keep the cell cycle functioning as it should. Explain the roles of these two types of genes, and explain what can occur when these types of gene are not working properly. Provide at least two different examples of cancers associated with mutations of these types of genes.

The purpose of the proto-oncogenes under normal circumstances is to make sure that cells proliferate, in other words the oncogenes stimulate cell production. But when a normal, healthy ocogene cell becomes mutated or expresses at higher than normal levels it causes cancer. The first oncogenic virus was discovered in 1916 and called the Rous virus after the person who discovered it, Peyton Rous. Rous viruses represent a family of viruses called the retro viruses. Retro viruses contain a genetic material called ribonucleic acid (RNA).

There is always the possibility that RNA will be transcribed into DNA (deoxyribonucleic acid) by an enzyme of ...

1. When placed on an agar slab and incubated at 30°C for 2 days, a single yeast cell proliferates into a colony with a diameter of 2 mm containing 108 yeast cells. If the cell has a functional Ade2 gene (Ade2+), the colony will be white; if Ade2 is non-functional (Ade2–), the colony will be red. You take a strain with a mutant Ade2– at the regular chromosomal position (red colonies) and insert a second, functional Ade2+ gene near the telomere. You find that the colonies are a mixture of red and white patches or sectors. Figure 1 shows some colonies; the black regions represent the ...

Living organisms depend on biochemistry to power various chemical reaction cycles which are important for the overall biological functioning of an organism. Chemical reactions occur at a specific rate in certain conditions and require input energy (activation energy) to be supplied before a reaction can begin. Since a reaction cycle consist of many consecutive step, slowing one step slows down the whole cycle. Enzymes are proteins which act as catalysts in biochemical reactions and speeds up reactions to rates that are high enough for biological functioning. Enzymes manage this by providing an alternative reaction route with lower activation energy.

The human body is constituted in about 20% by protein. Proteins, on their hand, are constituted by amino acids. Therefore, the intake of proteic food is very important so that the proteins of such foods may be metabolized and the amino acids and energy gathered to maintain the body’s protein levels.

The existence of correct amounts of amino acids in the body is essential for several functions:

- the body’s skeletal muscle constitution; - for transport of nutrients to the same cells; - cell repair; - cell communication: - influence on organs’ good function; - eliminating residues from metabolism; - amino acids are also nutrients in itself, ...

Report on Case 1: Diagnosis of Hereditary Fructose Intolerance

Enzymes act as biological catalysts, they speed up biological reactions and are also capable of regulation. Enzymatic reactions can be anabolic – where a new substance is built from smaller ones; or catabolic – where a substance is broken down to yield simpler molecules. In the example of fructose, enzymes catabolize this simple sugar to substances that are intermediates of the glycolytic pathway, allowing fructose, a 6-carbon sugar, to be used by cells to obtain energy in a way similar to glucose (also a 6-varbon sugar). Aldolase B is one of the enzymes involved in the catabolism of fructose, and its deficiency results in ...

Enzymes as Catalysts

All known enzymes are catalysts. Enzymes have a number of properties that make them catalysts. To begin with, enzymes accelerate the rate of a chemical reaction without being used up them or altered by the reaction (Luciano, 1983).similarly; enzymes accelerate rates of chemical reactions without changing the equilibrium between the products and reactants of the reaction.

Metabolism of Fructose in the Liver

Once fructose is absorbed, it is rapidly taken up by the liver by glucose transporter, GLUT2(Bozzetti,2006).The fructose in the liver is rapidly metabolized by the enzyme fructokinase into fructose -1-phosphate.Aldolase B enzyme acts on the substrate fructose -1-phosphate.The enzyme metabolizes fructose-1-phosphate ...

Rickets can be referred to as the softening, as well as weakening of bones, commonly due to an extreme and extended deficiency in vitamin D. Vitamin D enhances phosphorus and calcium absorption from the digestive tract. A vitamin D deficiency renders maintenance of proper levels of phosphorous and calcium difficult resulting in rickets. Addition of calcium or vitamin D or o the diet in general corrects any resulting problems for a child. Rickets resulting from a genetic condition may need extra or other medications. A number of skeletal deformities resulting from rickets may require restorative surgery. Symptoms of rickets include ...

Abstract:

DNA (Deoxyribonucleic acid) is hereditary material found in most organisms and carries the genetic information required to build and maintain a living organism. DNA was first discovered in the late 1800's, but it was not until scientists unraveled its structure in the 1950s that its importance in genetics and the whole field of biological sciences became realized. This paper assesses the structure, history and applications of DNA into solving real world problems in medicine, agriculture, biochemical research and forensics. DNA can replicate itself which ensures that genetic information and consequently biological traits can be passed on from one generation to ...
