| Hazard Information | Back Directory | [Uses]
Dehydro-L-(+)-ascorbic acid dimer has been used to study its transformation and stability under the influence of pH, concentration and temperature. | [Definition]
ChEBI: Dehydroascorbic acid dimer is an organic heteropentacyclic compound obtained by cyclodimerisation of ascorbic acid. It is an organic heteropentacyclic compound, a tetrol and a cyclic hemiketal. | [Biological Activity]
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. It is used in a wide variety of applicationsincluding cell culture. It also acts as a reducing agentth at helps reduce oxidative stress. L-Ascorbate can be regenerated from dehydroascorbic acid (DHA) by biological systems. |
