Dehydroascorbic acid

Dehydroascorbic acid (DHA) is an oxidized form of ascorbic acid (vitamin C) and 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.

Chemistry

Dehydroascorbic acid is an organic compound that is an oxidized form of ascorbic acid. 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.

Biological role

In humans, dehydroascorbic acid is a form of vitamin C, although it is less active than ascorbic acid. It is a strong antioxidant that protects the body from damage by free radicals and reactive oxygen species, which are produced during normal metabolism and in response to environmental stressors such as exposure to ultraviolet light and pollution.

Health implications

Dehydroascorbic acid has been studied for its potential role in a variety of health conditions, including cancer, cardiovascular disease, and neurodegenerative disease. Some research suggests that it may have anti-cancer properties, although more research is needed to confirm these findings.
