Lgulono14lactone
Lgulono14lactone, also known as L-gulono-1,4-lactone, is a lactone derived from L-gulonic acid. L-gulonic acid is a naturally occurring carbohydrate that is an intermediate in the L-ascorbic acid (vitamin C) biosynthesis pathway in many animals, although humans and some other species lack the final enzyme necessary for this conversion. Therefore, L-gulonic acid and its lactone form are not directly synthesized by these organisms and must be obtained through diet or supplementation.
Lgulono14lactone is a cyclic ester that can exist in equilibrium with its open-chain form, L-gulonic acid. This
While L-gulono-1,4-lactone itself is not vitamin C, it has been studied for its potential biological activities.
