[L. purum, pure, + uricus, uric acid]
The parent compound of nitrogenous bases, including adenine, guanine, xanthine, caffeine, and uric acid. Purines (chemical formula C5H4N4) are the end products of nucleoprotein digestion, and are catabolized to uric acid, which is excreted by the kidneys. Adenine and guanine are synthesized within cells for incorporation into DNA and RNA.
