Yes, it contains caffeine, which is a xanthine
Xanthine oxydase is a protein enzyme containing iron and molybdenum which promotes the oxidiatization of hypoxanthine and xanthine to uric acid.
Xanthyl is a radical derived from xanthine.
Molybdenum is in the Xanthine Oxidase family.
If you type in the full question from today's Telegraph GK crossword, you will find the answer - I did!
Xanthinuria is a presence of an abnormally high level of xanthine in one's urine.
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)
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.
A xanthin, also spelled xanthine, is one of a group of alkaloids which include caffeine, theophylline, and theobromine, a precursor of uric acid.
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"
