It is not significant amount, but it seemed to be enough. A reason for some loss in my data was that some of the crystals were lost in the process of removing the inner tube. In addition, although I was unable to perform the NMR, I perform the IR, but my spectra resemble more like a blank. I obtain 0.05 grams of pure crystal caffeine but it could be that during my removable of the inner tube that when both of the tube accidently bumped that I lost some of the crystals, which resulted in not enough caffeine for me to get an IR spectra with all the peaks.

Tests performed on these theories show that animals deprived from sleep suffer from a loss of all their immune system functions and inevitably die from this in only a few weeks’ time. Studies show that muscle growth, tissue repair, protein synthesis, and growth hormones are most active while you sleep, and even a few are only active while you sleep. While we are conscious and awake our brain produces a chemical called adenosine, this chemical is thought to be the cause of why we feel tired at times and feel the need to sleep, this chemical is countered by caffeine. That explains why you feel more awake and alert after drinking that cup of Joe. Caffeine actually blocks the receptors for adenosine making that feeling of being tired and not alert diminish. While you sleep it gives the body a chance to clear the adenosine from the system, in turn making you feel “refreshed” and not tired when you wake up from your slumber.

　　　　Caffeine is a stimulant drug that acts on the brain and the central nervous system. It is recognized as the world’s most psychoactive drug. It mimics the shape and size of adenosine which is a chemical that promotes sleep and suppresses arousal. What caffeine does is that it blocks the adenosine receptors. Since it impersonates adenosine, the receptors fail to differentiate caffeine and so caffeine can bind to the receptors in your

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.

First, it increases alertness. This can be done through three major procedures: firstly, the concentrated caffeine in the coffee can mobilize the calcium in the cells and restrain certain enzymes. Secondly, while decreasing the cerebral blood flow it increases the energy metabolism throughout the brain. Thirdly, it releases dopamine and activates the noradrenalin neurons which cause alertness effect. But the problem with caffeine is that many people develop physical dependence upon the consumption of caffeine which later turns into addiction. Another known effect of caffeine as a stimulant is the relieving of headaches. This is achieved because caffeine blocks the adenosine receptors in the brain. These specific receptors control many other neurotransmitters and by blocking the adenosine receptors the cerebral blood flow is constricted. As a result, the release of the excitatory neurochemicals helps relieve the feeling of headaches. Another effect is the increase in the production of gastric acid. Normally, during digestion gastric acid is produced to work on the proteins and break them down into amino acids. While, in the presence of caffeine gastric acid is produced even in the absence of the gastric acid which causes irritation in the linings of the stomach and the duodenum. Finally, the caffeine stimulates the colon on increasing peristalsis. Routinely, the
