Chemistry Of Caffeine

This article discusses the affects caffeine has on several aspects of human health. These included toxicity, cardiovascular effects (arrhythmia, heart rate, cholesterol and BP), bone/calcium balance, behavior, and reproductive and developmental effects. It also discussing the affect caffeine intake has on children and reproductive-aged women.

Caffeine is a mild stimulant that occurs naturally in at least 63 plant species. Caffeine can be found in the leaves, stems, seeds, and roots of these various plants. Caffeine is part of the methylxanthine family. It consists of a xanthine molecule with three methyl groups attached to it. Caffeine can be found in many products like sodas, tea, and coffee, but it also occurs in several other products such as prescription medications, diuretics, and pain relievers. Caffeine’s widespread use and popularity have caused many people to view the substance as an addictive drug. Thus making caffeine the most inexpensive and readily available drug known to man. Then on the other hand there are

Every day, people all over the world begin their days with a cup of coffee, or some other form of caffeine to give them the energy “boost” that gets them going. In recent years, caffeine is becoming more common and easier to consume with the abundance of energy drinks on the market. This use of caffeine is widely known and taken advantage of, however, caffeine can have some other important effects on our brains as well, including being used in medicines that need to be sent to the brain. Caffeine also has the ability to provide a boosting benefit for the brain, both in the short term and the long term, by interacting with numerous chemical pathways, especially those involving adenosine, in the brain, typically by inhibitory effects.

Caffeine is found in many plant species, where it acts as a natural pesticide. It is found most commonly in cocoa, tea and coffee, but is also artificially added to some soft drinks such as cola to act as a flavour enhancer. When consumed by humans, caffeine works as a stimulant causing amounts of released neurotransmitters to be increased. High use of caffeine has been related with raised blood pressure, restlessness, insomnia and anxiety which, in the long term, can lead to heart and circulation problems.

The caffeine in coffee doesn't actually give us energy, not directly at least. In our brains is a chemical called adenosine, which is associated with drowsiness, or sleep. Caffeine takes up the adenosine receptor slots in the brain. In essence, it is preventing your brain from growing tired. This is how coffee gives us the feeling of "wakefulness". In addition to this, the caffeine also causes your heart rate to increase, your blood vessels to constrict, and your air passages to relax. Furthermore, you're brain will start to notice all of the activity occurring, which in turn activates our fight or flight response, releasing adrenaline into our

Meta Description: Are you worried that your coffee drinking might be affecting your sleep? Here is a quick guide to the effects caffeine might have on your body and sleep.

While low to moderate doses of caffeine do not include any of these negative side effects, as mentioned before it has the opposite effects. When caffeine is taken in doses higher than 250 mg it also may raise blood pressure and increase anxiety levels (Feeley 7). Not only will extremely high doses of caffeine cause unpleasant symptoms, but if taken in large amounts for a long period of time the consumer’s body will become dependent upon caffeine. Caffeine in definition is a drug and like any other drug the body will eventually become dependent upon it. Sudden removal of caffeine from the diet also cause displeasing symptoms like headaches, anxiety, vertigo, chills, muscle stiffness, and increased fatigue (Caffeine - Benefits and Risks) (Smith

Coffee is my life. I need coffee twice a day to keep me going. Coffee consist of caffeine and when I can’t get coffee I turn to other caffeine methods like chocolate, sodas, or tea. The section of the effects of drugs on the nervous system-caffeine was very interesting. It relates to what is caffeine, how it affect our bodies, and how it is a physical dependence. Caffeine is a stimulant for our central nervous system. “In moderate dosage, it increases alertness, reduce fine motor coordination, cause insomnia, headaches, nervousness, and dizziness” according to washington.edu. In high dosage caffeine can be dangerous and cause death. Caffeine is in the xanthine chemical group, adenosine is a naturally occurring xanthine in the brain that is used as a neurotransmitter for some synapses; caffeine interferes with adenosine at sites in the brain. The over use of causes physical dependence, this can cause a withdrawal is the need is not met. The withdrawal is unpleasant and can cause agitation. As you can see, caffeine truly effects our nervous system and even explain some points in the biopsychology chapter and chapter 4 because of physical dependence,

It is known that caffeine in the body raises blood pressure. It is a natural substance that is extracted from plants; common sources of caffeine are from coffee beans, cocoa, tea-leaves and can also be produce synthetically. It promotes alertness, also known as the anti-adenosine. Adenosine is a substance in the body that promotes sleep and with caffeine in the blood stream the adenosine receptor is block thus keeping the body fully awake. Caffeine usually reacts very quickly in the body; it peaks up in the blood within 30 to 60 minutes and has a half-life of 3 to 5 hours. Half-life means the time the body can eliminate half of the drug and half that is retained in the body for a long period. Caffeine is effective if taken on off-and-on basis.

In general, caffeine alters the way our brain communicates to the central nervous system by imitating or changing the release and uptake of neurotransmitters. Caffeine is consumed to awaken and make people alert, however, there are other effects caffeine has on our body. Adenosine, the neurotransmitter that makes us tired, is just one neurotransmitter that is affected by caffeine consumption. For example, if the transmission of dopamine increases, caffeine improves our mood, and may even protect brain cells against age and disease (Weinberg & Bealer, 2015). In addition, if the activity of acetylcholine increases, caffeine increases muscular activity and potentially could improve long-term memory. And lastly, if the level of serotonin adjusts,

Caffeine is a stimulant drug and the most widely-consumed mid-altering substance in the world. Most of the effects of caffeine are thought to be traceable back to its action as an antagonist at receptors for adenosine, a neurotransmitter. Caffeine binds to adenosine receptors and blocks adenosine from binding there and activating the receptor; thus, it reduces activity at the adenosine receptor. Although there are four subtypes of adenosine receptor, most of caffeine’s effects are thought to be due to its antagonistic actions at the A1 and A2A subtypes. Its ability to produce wakefulness may be especially due to actions at the A2A receptor subtype. How exactly the antagonism of the adenosine receptor translates into the effects of caffeine

Caffeine can make people more awake, alert, and able to concentrate. Throughout the day, a chemical called adenosine builds up in the human body. The nervous system has special receptors to monitor adenosine levels. As the day goes on, more and more adenosine passes the receptors making people sleepy. When consuming caffeine, the receptors bind together, stopping the adenosine from passing the receptors. This process leaves people feeling more awake and focused (Caffeine Informer

Caffeine has a huge effect on the body and mind. It can lead to a kind of addiction. Many people feel like they need caffeine to function in their daily routine. Without caffeine in their system their body may begin to shut down. The most popular beverages in the United States, such as coffee, tea, and soda, contain significant amounts of caffeine. Caffeine is a stimulant and the most commonly used drug in the world. Every day, millions consume it to increase wakefulness, alleviate fatigue, and improve concentration and focus. Other stimulants may have the very similar effects on the body, the symptom similarities are uncanny.

Caffeine is the most widely consumed psychoactive drug in the world. It stimulates the central nervous system. It is classified in the methyxlxanthine class of central nervous system stimulants. One reason it is different from other psychoactive substances is that it is legal and almost completely unregulated throughout the world. Caffeine’s most felt effect is it causing a stop in the action of adenosine. Adenosine is a compound consisting of adenine combined with ribose, one of four nucleoside units in RNA that tries to cause the person to sleep. This causes the most common effect of caffeine which is being very awake and being a bit what some would call

Caffeine has many negative effects on humans, such as increased heart rate (Lane, J.D., 2002), depression (Goldstein, 2008), and addiction to this “drug.” You may be asking yourself, “What is caffeine?” Well, caffeine is actually a stimulant (Barone, Roberts, 2008) that is found in beverages such as tea, coffee, and soft drinks. In fact, caffeine is the highest grossing and most used stimulant in the United States (Barone, Roberts, 2008). It is estimated that 85% of adults living in the United States consume caffeine on a daily basis (Barone, Roberts, 2008). That means for every 100 adults, 85 of them have had a drink that contained caffeine on any given day. One reason caffeine is so widely available compared to other stimulants is
