C16H22N2O6 (338.1478)

Nicotine glucuronidation results in an N-quaternary glucuronide in humans. This reaction is catalyzed by uridine diphosphate-glucuronosyltransferase (UGT) enzyme(s) producing (S)-nicotine-N-beta-glucuronide (Nicotine-Gluc). About 3-5\\% of nicotine is converted to Nicotine-Gluc and excreted in urine in humans. [HMDB] Nicotine glucuronidation results in an N-quaternary glucuronide in humans.
