Yes, it contains caffeine, which is a xanthine
Xanthine oxidase is an enzyme that plays a role in the process of purine metabolism. It is responsible for converting purines into uric acid. Inhibition of xanthine oxidase is a common target for medications used to treat conditions such as gout.
Xanthyl is a radical derived from xanthine.
Molybdenum is in the Xanthine Oxidase family.
Xanthinuria is a presence of an abnormally high level of xanthine in one's urine.
Technically a fast is no food or drinks, except for water. Chocolate can fall under either category (food or drink). During a liquid fast, it can be drunk, most likely in the form of chocolate milk or hot chocolate.
Allopurinol is a structural isomer of hypoxanthine (a naturally occurring purine in the body) and is an enzyme inhibitor, inhibiting xanthine oxidase. Xanthine oxidase is responsible for the successive oxidation of hypoxanthine and xanthine resulting in the production of uric acid, the product of human purine metabolism. In addition to blocking uric acid production, inhibition of xanthine oxidase causes an increase in hypoxanthine and xanthine, which are converted to closely related purine ribotides adenosine and guanosine monophosphates. Increased levels of these ribotides causes feedback inhibition of amidophosphoribosyl transferase, the first and rate-limiting enzyme of purine biosynthesis. Allopurinol therefore decreases both uric acid formation and purine synthesis. (source wikipedia)
A xanthin, also spelled xanthine, is one of a group of alkaloids which include caffeine, theophylline, and theobromine, a precursor of uric acid.
xanthine oxidase catalyzes the oxidation of purines (the bicyclic nitrogenous bases in genetic material) to form uric acid. Uric acid is then excreted.xanthine oxidase reduces water and oxygen to hydrogen peroxide in the process.(Nelson D.L.; Cox, M.M., Lehninger Principles of Biochemistry. 4th ed., New York: W.H. Freeman, 2004, 35.) xanthine oxidase is also carried by some white blood cells to produce hydrogen peroxide and other forms of reactive oxygen, as part of the inflammatory response in many mammals. For example, tobacco smoke causes the production of more xanthine oxidase and more reactive oxygen species.

it belongs to the xanthine oxidase family. i checked about a million sights, and they all said that
You probably have gout, a purine metabolic disorder. Uric acid crystals are not completely hydrolyzed and eliminated through the kidneys. xanthine oxidase and xanthine dehydrogenase are not completely catalyzed and leave toxic free radicals in your peripheral nervous system.. backward character
Theophylline, it acts as a bronchodilator to reverse the bronchoconstriction associated with asthma.
It is a stimulant which you might want to avoid during pregnancy.It contains "methyl xanthine alkaloids"
