| diphosphoric acid | |
| Orthophosphate | |
| Magnesium | A metallic element that has the atomic symbol Mg, atomic number 12, and atomic weight 24.31. It is important for the activity of many enzymes, especially those involved in OXIDATIVE PHOSPHORYLATION. |
| xanthosine | |
| xanthine | A purine base found in most body tissues and fluids, certain plants, and some urinary calculi. It is an intermediate in the degradation of adenosine monophosphate to uric acid, being formed by oxidation of hypoxanthine. The methylated xanthine compounds caffeine, theobromine, and theophylline and their derivatives are used in medicine for their bronchodilator effects. (Dorland, 28th ed) |
| xanthosine monophosphate | |
| ribose 1-phosphate, (alpha-D)-isomer |
