Dehydroascorbic acid

Description:
Dehydroascorbic acid (DHA) is the oxidized form of ascorbic acid (vitamin C) and is characterized by its chemical formula C6H6O6. It appears as a white to pale yellow crystalline powder and is highly soluble in water. DHA plays a crucial role in biological systems, particularly in its ability to act as an antioxidant, scavenging free radicals and protecting cells from oxidative stress. It can be readily converted back to ascorbic acid in the presence of reducing agents, which highlights its importance in metabolic processes. The substance is sensitive to light and heat, which can lead to its degradation. In terms of stability, dehydroascorbic acid can undergo hydrolysis and polymerization, especially in aqueous solutions. It is commonly used in food preservation and as a dietary supplement due to its health benefits. Additionally, DHA is utilized in various biochemical applications, including research and clinical settings, to study vitamin C metabolism and its effects on human health.
