L-Gulono-1,4-lactone (Standard)

L-Gulono-1,4-lactone (L-Gulonolactone) (Standard) is the analytical standard of L-Gulono-1,4-lactone. This product is intended for research and analytical applications. L-Gulono-1,4-lactone is a biosynthetic precursor of L-Ascorbic acid (Vitamin C) (HY-B0166). L-Gulono-1,4-lactone can be enzymatically converted to L-Ascorbic acid via the animal uronic acid pathway, while species such as humans lack the key oxidase that catalyzes this step, resulting in the disruption of this pathway and the necessity to obtain Vitamin C from diet. L-Gulono-1,4-lactone is a putative intermediate in an alternative biosynthetic pathway of L-Ascorbic acid in Arabidopsis thaliana.
