Caffeine Essays

The word “caffeine” originated from the French word “café”, which means “coffee.” Caffeine’s chemical name is 1,3,7-trimethylxanthine, primarily based on its formula, C8H10N4O2, and molecular structure. Caffeine is a stimulant that occurs naturally and can be isolated from around 60 plants and can synthetically be made and added to ordinary products and medicinal drugs. Caffeine in it’s pure form is a white powder that is very bitter. A major chunk of the population makes use of caffeine as a stimulant

maximum isloristite. Magic beans belong to the world of fairy tales, but with each new research on the effects of caffeine, the more it looks like the coffee beans really has something magical. After the ban of ephedra in the US and in some other countries, caffeine further gains in importance as a supplement to burn fat, and increase endurance and intensity of training. Does caffeine really that good? Do you really can have all of these aforementioned effects? The answer is loud and clear: Yes! Let's

“Effect of Caffeine on Leg-Muscle Pain During Intense Cycling Exercise: Possible Role of Anxiety Sensitivity” Article Summary Rachael C. Gliottoni and Robert W. Motl wrote the article entitled “Effect of Caffeine on Leg-Muscle Pain during Intense Cycling Exercise: Possible Role of Anxiety Sensitivity” focuses on the possible effect of caffeine on the opinions of leg pain. Published by the International Journal of Sport Nutrition and Exercise Metabolism, the researchers had sixteen college-age women

Most people depend on that one cup of coffee to get them through the day. People are dependent on caffeine to get them going. My question is why is caffeine so addictive? Caffeine is a psychoactive drive that stimulates your body. It is in the same class as cocaine, amphetamines, and heroin though caffeine is less potent. People do not typically see caffeine as a drug of that is as addicting as other psychostimulants. These “other psychostimulants, such as amphetamines and cocaine, elevate the extracellular

previous knowledge I knew that caffeine gives energy to your body, I decided to see how it enhances athletic performance. Caffeine has been shown and proven to enhance athletic performance. It enhances endurance for long distance runners and decreases muscle fatigue. Not only does caffeine have an effect on physical aspect it also effects mental energy. Caffeine improves alertness and also strengthens muscles. I performed tests and found that the effect of caffeine on an athlete is really helpful

Caffeine is a chemical found naturally in few plants all over the world. From these plants it is processed into its pure form and then put into other things such as soda, energy drinks, tea, and pills. Energy drinks and soda are some of the most widely marketed products in the world, even though they contain the highest concentration of caffeine outside of pure caffeine supplements. It is a stimulant that affects everyone in strange but semi predictable ways. Research has been done on this topic

there are caffeine and sugar in coffee that has pros and cons which affects consumers’ health such as physical health or mental health: increasing heart rate, obesity, headaches, blood pressure, etc. So, customer should be aware of the danger of consuming too much coffee, especially teenagers should reduce the amount coffee in their diet. From past to present coffee is a beverage that many people usually drink it along side breakfast, lunch or dinner. For example, Americans

Since humans discovered caffeine, the common commodity has been used as an ingredient in several foods and beverages, most commonly in coffee, been used in the medicinal industry, been used by workers to stay awake ever since the industrial revolution, to fuelling the economy on the global scale; clearly demonstrating the process of increasing complexity. The origins of caffeine can be traced all the way back to the period of time where Earth was forming. When Earth formed and cooled down, it fitted

Caffeine ranks as the world's most widely consumed drug. Researchers at Villanova University present that up to 90% of adults consume consume caffeine in some form every day(Villanova.edu). Coffee represents the largest source of caffeine consumed by Americans, but many food companies are beginning to add caffeine the products that might not generally contain the substance. Not only do these new products increase average caffeine consumption, they also allow caffeine to be more available and attractive

Researchers of Caffeine According to Bennett Allan Weinberg and Bonnie K. Bealer (2001) Caffeine in its pure form was not known until 1820. However, the properties of caffeine are already recognized long before the drug itself is known. Walter Rumsey (1584-1660) A welsh judge observed in a book chapter entitled Experiments of Cophee that coffee had the “ power to cure drunktards”. The theory survive today in the prevalent but inaccurate belief that a cup of strong coffee can make a drunk person

Caffeinated beverages are a popular source of energy that works to increase reaction times and improve awareness. The experimenter’s hypothesis that people who drink two or more caffeine drinks a day have a faster reaction time than those who drink zero to one caffeine drinks a day. In this study 14 adults from the University of Maryland University College Psych 300 class participated in an online reaction test. The participants were divided into two groups based off the results of a self-reported

the effects of caffeine on athletic performance. We chose to conduct this experiment because of our combined interests in athletics and the medical field. Researchers have studied the effects of caffeine on athletic performance, concluding that it can enhance performance and agility. After reviewing some of these studies, we believe if caffeine levels are increased, then the time taken to run a lap around the soccer practice field will decrease when time is a function of caffeine level. To test

Caffeine is a substance that is found not only in coffee, but other beverages and foods like tea, energy drinks, chocolate, and in various seeds, fruits and leaves of plants. Although studies have found that coffee and tea have many chemical components with beneficial effects, one of these components, caffeine has earned a bad reputation with some people because of its stimulant effects. Some people crave it, while others avoid it. There are many reasons for people to love or hate caffeine, but not

I. Introduction Caffeine as we all know is a kind of stimulant in our central nervous system and classified as methylxanthine. It also stimulates some other parts of our autonomic nervous system. This substance was mainly found in the seeds or leaves of a certain plant. A well known example of this plant is the coffee bean. Thus, to calculate the caffeine content of soft drinks, we may use the process of HPLC. And as we define HPLC (High performance liquid chromatography)

Caffeine is a central nervous stimulant that is in coffee beans, cocoa beans, and in tea leaves. In very large proportions, caffeine can be toxic. In large doses it can result into vomiting, convulsions, arrhythmia (a quivering heart), tachycardia, coma, and even death (Kerrigan & Tania, 2005). A person can have up to 400 milligrams of caffeine a day for adults. That is roughly about four cups of brewed coffee, 10 cans of cola or two “energy shot” drinks. Adolescents should limit themselves to 100

into drinking coffee because they believe that it increases their energy and helps to concentrate better. We have decided to investigate the placebo effect and see how the type of caffeine affects one’s concentration and heart rate. Safety Hazards Don't leave the kettle unattended Do not give a dangerous amount of caffeine to the participants. Make sure you wear the proper attire for the experiment.

IUPAC nomenclature system. Despite caffeine and caffeic acid share almost the same name, both of them is not related because of difference in functional group and molecular structure. In human body, caffeine is rapidly absorbed from alimentary system into the circulatory system, which will be transported via blood plasma. Half-life of caffeine is averaged from 2.5 hours to 4.5 hours, yet varied differently from person to person, Ruxton (2009). In medical field, caffeine is used for several treatments

Caffeine, everyone has tried it; who would not like getting up on a cold, blistery morning to a welcomed cup of hot coffee. Or, those who have found that coffee is an applauded relief that just makes their day function that much smoother. Long hours at work, no problem; just have another cup to push one’s drained energy to Machiavellian those needed overtime hours. Adrenaline rush can be very stimulating, especially if that artificial stimulating process happens rather quickly. All of a sudden, before

Caffeine. It helps millions of people wake up and feel better in the morning. It helps them stay awake on the road. It gives them something nonalcoholic to drink socially. And it gives people that extra burst of energy we all seem to need sometimes. But do people realize when they take that sip of coffee, or bite into that bar of chocolate they are contaminating their body with what could be a very dangerous drug? Because that's just what caffeine is, a drug. According to Richard J. Gilbert, Ph.D

For the purposes of this lab, only three other chemical constituents of tea were considered during the chemical extraction of caffeine from tea. These chemicals were cellulose, tannins, and chlorophyll. Of course, there are many other chemicals in black tea, including various lipids and carboxylic acids ; however, many of these chemicals are not present in large enough quantities to separate using the methods available to an undergraduate lab, and therefore these chemicals are collectively considered
