Dehydroascorbic acid

Description:
Dehydroascorbic acid (DHA) is the oxidized form of ascorbic acid, commonly known as vitamin C. It is a white to pale yellow crystalline powder that is soluble in water and exhibits a slightly acidic pH. DHA is known for its antioxidant properties, which allow it to scavenge free radicals and protect cells from oxidative stress. In biological systems, it can be readily converted back to ascorbic acid, thus playing a crucial role in various metabolic processes. Dehydroascorbic acid is sensitive to light, heat, and air, which can lead to its degradation. It is commonly found in fruits and vegetables, particularly in processed foods where ascorbic acid may oxidize. In addition to its nutritional significance, DHA is utilized in various pharmaceutical and cosmetic applications due to its ability to enhance skin health and promote collagen synthesis. Its CAS number, 33124-69-5, is used for identification in chemical databases and regulatory contexts. Overall, dehydroascorbic acid is an important compound in both nutrition and biochemistry.
