Common NameCaffeine
DescriptionCaffeine, also known as coffein or mateina, belongs to the class of organic compounds known as xanthines. These are purine derivatives with a ketone group conjugated at carbons 2 and 6 of the purine moiety. When considered comprehensively, findings from experimental and epidemiologic studies converge to show that BP remains reactive to the pressor effects of caffeine in the diet. Caffeine is a drug which is used for management of fatigue, orthostatic hypotension, and for the short term treatment of apnea of prematurity in infants. Caffeine is an extremely weak basic (essentially neutral) compound (based on its pKa). Within humans, caffeine participates in a number of enzymatic reactions. In particular, caffeine can be converted into paraxanthine and formaldehyde through its interaction with the enzyme cytochrome P450 1A2. In addition, caffeine can be converted into theobromine and formaldehyde; which is catalyzed by the enzymes cytochrome P450 1A2 and cytochrome P450 2E1. In humans, caffeine is involved in caffeine metabolism. Caffeine is a bitter and odorless tasting compound. Outside of the human body, Caffeine is found, on average, in the highest concentration within a few different foods, such as arabica coffee, coffee, and tea and in a lower concentration in frozen yogurts, coffee mocha, and other beverages. Caffeine has also been detected, but not quantified in, several different foods, such as common chokecherries, garden onions, hushpuppies, cherry tomato, and florida pompano. This could make caffeine a potential biomarker for the consumption of these foods. Caffeine is a potentially toxic compound.
