Dehydroascorbic acid

Dehydroascorbic acid (DHA) is an oxidized form of ascorbic acid (vitamin C). It is actively imported into the endoplasmic reticulum of cells via glucose transporters. It is trapped therein by reduction back to ascorbate by glutathione and other thiols. The (free) chemical radical semidehydroascorbic acid (SDA) also belongs to the group of oxidized ascorbic acids.

This article is about the vitamin C metabolite. For the omega-3 fatty acid also abbreviated as DHA, see Docosahexaenoic acid.
