1,5-Anhydroglucitol

1,5-AG; 1,5-Anhydroglucitol

1,5-Anhydroglucitol (1,5-AG) is a naturally occurring polyol, or sugar alcohol, found in the body and derived primarily from dietary sources. It's structurally similar to glucose but lacks the hydroxyl group at the C1 position, meaning it cannot be metabolized by the body.
