Beschreibung

Allgemeine Beschreibung

Dehydro-L-(+)-ascorbic acid dimer is a water soluble molecule,[1] which is produced by vitamin C in the lumen of gastrointestinal tract.[2]

Anwendung

Dehydro-L-(+)-ascorbic acid dimer has been used to study its transformation and stability under the influence of pH, concentration and temperature.[3]

Biochem./physiol. Wirkung

Dehydro-L-(+)-ascorbic acid dimer is used to regenerate ascorbic acid(AA). AA oxidation to dehydroascorbic acid (DHA) takes place in extracellular fluid and cells. AA acts as an antioxidant and enzyme cofactor.[2] It is used in a wide variety of applications, including cell culture. It also acts as a reducing agent, that helps reduce oxidative stress. L-Ascorbate can be regenerated from dehydroascorbic acid (DHA) by biological systems.[1]
