Caffeine Reports Samples For Students

Abstract

This is a lab report that examines an empirical study of the role of caffeine in the human body and impact and reason for continuous consumption of caffeine. The research involves a study of 1060 respondents who are examined in various elements and aspects of the effects of caffeine on them.
The research identifies that there is an empirical evidence of an increase in energy levels amongst people who consume coffee. However, this change is not so large when compared to consumers of Rooibos tea. Also, the research indicates that energy levels are not significantly increased by people who take ...

Introduction and Literature Review

The value for a drug is significantly impacted by the dissolution rate, chemical stability and solubility of the drugs thereby impacting the pharmaceuticals efficiency as well. In the pharmaceutical industry multi-component crystals such as hydrates, solvates, co-crystals and salts have a major role during the design of new solids. Solid does not self-crystallize. It crystallizes in varied forms depicting random crystal properties. Various approaches are used to modify solids like Salting, Solvation, Hydration, and Polymorphism. Apart from these approaches, Co-Crystallization is a promising new approach to modifying solids (Nauha, ...

Caffeine is present in tea leaves and can be readily extracted. This is the producer that was demonstrated in this laboratory experiment. In the laboratory experiment, the teabags were heated to ebullition for five minutes. The ebullition was sequenced by an extraction which applied dichloromethane. All of the washings occurred in a separator funnel. The residual substrate was subsequently evaporated up to the point of where the crude caffeine remained as a residual. Sublimation was applied in order to separate the purified caffeine from the crude caffeine. The mass of the sublimate is was 0.0035g. The percentage yield of the caffeine ...

- Purpose
The purpose behind conducting this experiment is to separate or extract Caffeine, which is an alkaloid and a weak organic base from the de-carbonated cola drink.
- Procedure
- A 125mL separatory funnel supported by an iron ring is taken and positioned on an iron stand. 60mL of de-carbonated cola drink is then transferred into it followed by the addition of 5.0mL Methylene Chloride (CH2Cl2) and insert the stopper.
- The pressure built inside the flask must be released by inverting it and opening up the stopcock instantly. The stockcock must be closed again ...

Abstract

Animals whose body temperatures are affected by their surroundings are said to be ectothermic. If an ectothermic organism is exposed cold conditions, the heart rate of the animal lowers. In high temperatures the heart rate of the animal is very high. Caffeine being a stimulant works by causing the nervous system to work faster. It further leads to the constriction of the blood vessels. The Daphnia magna sometimes referred to as the water flea lives in the fresh waters. It is an exothermic crustacean. The results of Table one shows that Daphnia’s heart rate lowers as temperatures the temperatures ...

Introduction

Caffeine is an ingredient in a variety of beverages including coffee, tea, chocolate drinks, cola drinks. Caffeine is also included in some prescription medications (McKinley Health 2004). Caffeine has long been regarded as an ergogenic aid as it has been shown to increase muscle contractibility, aerobic endurance and enhancement of fat metabolism. (McKinley Health 2004). Caffeine acts as a mild stimulant to the central nervous system and the effects of caffeine can be modulated by the subject’s age and body mass (McKinley Health 2004). Caffeine has been shown to improve performance, including endurance, when taken prior to exercise (Ryu et ...

Caffeine occurs naturally in more than 60 plants including tea leaves, coffee beans, cacao pods and kola nuts-used to flavor soft drink colas (Medicines in my Home, 1). Worldwide, 90 percent of people consume caffeine in different forms. The use of caffeine has several effects to the human body.

Caffeine changes the working of the brain and the body by stimulating the central nervous system-brain, spinal cord and the nerves. Caffeine makes one feel more awake and alert. This is a major reason why people take it (Snel, 3). Moreover, caffeine is used as a prescription and over-the-counter drug to improve ...

Aims and Objectives of the Experiment

The aim of this experiment is to study the separation of an extract of a non-prescription analgesic tablet containing acetylsalicylic acid (aspirin) and caffeine. The separation is achieved through a well-known process called liquid chromatography. The quantities of the aforementioned substances also need to be determined in the experiment (“High Performance Liquid Chromatography,” n.d.).

Theory and Principles

Chromatography is a technique used for the separation of the components, or solutes, in a mixture. The separation is based on the amounts of the relevant solute in the moving, or fluid, stream. There are two phases in chromatography, the mobile phase, and the stationary ...

Analysis of Unknown using Standard Solutions and HPLC

Part 1.

The data for the construction of the standard curve for caffeine and benzoic acid are presented below.

The graphing of the Caffeine Standard Curve (figure 1) demonstrates an R2 of 0.9898 so this is standard curve is satisfactory for our experiment since 0.9898 approaches 1 closely.

The graphing of the Benzoic Acid Standard Curve shows a better fit as R2 = 0.9989. Each sample measuerment lies on the standard curve.

Part 2.

5 ml of warm Mello Yello was left to sit until the carbonation had released CO2 into the air (outgassing the cola). Then 2 ml of the outgassed cola ...

Introduction

The soft drink industry is one of the fastest growing business sectors in the world today. Different firms compete over the best products that attract customer attention by meeting their dietary, monetary, and refreshment needs. Much of these companies have embarked into the production of energy drinks. Red Bull GmbH is one of the globally recognized companies for its energy drink the Red Bull. The product finds a market in all parts of the world because of its uniqueness in content, flavor, originality, and the ability to supplement customer's energy. The paper discusses marketing analysis of Red Bull energy ...

Starbucks is currently one of the most successful companies worldwide. With over 16,850 shops in 40 countries and raking in revenues of $10.7 billion, it is clear that Starbucks is a coffee retail magnate. For fourteen straight years, they’ve maintained a 5% same-store sales growth. (Lepore, 2011). However, one does not climb to such great lengths without a strategic industrial plan. Such success is not a product of circumstance, but of in depth analysis and planning. This paper aims to thoroughly study Starbucks’s business plans through a strategic analysis model through its five components: industry ...

Introduction

The strategy is the purpose and direction an organization takes to get to its future and achieve long-term goals. It involves motivating trustees in the organization to engage meaningfully with the external environment. The organization, thus, matches its diverse capabilities with the needs of the stakeholders. An organization and in this case the MacDonald has a strategy that determines how the business relates to the outside world. It also determines how the organization will take every opportunity to innovate, improvise as well as make improvements. MacDonald should have a strategy that concentrates on priorities, making sure that the organization’ ...
