Alpha-Ketoglutaric Acid with CAS 328-50-7
What is Alpha-Ketoglutaric Acid?
α-Ketoglutaric acid — also known as 2-oxoglutaric acid, 2-ketoglutaric acid, or AKG — is a five-carbon α-keto diacid with the molecular formula C₅H₆O₅. It is best known as the rate-determining intermediate of the citric acid (Krebs) cycle, formed through the oxidative decarboxylation of isocitrate and further converted to succinyl-CoA in central energy metabolism.
Beyond its biological role, AKG has become a widely traded industrial and nutritional raw material. Runtai Chemical provides α-Ketoglutaric acid in food grade, pharmaceutical intermediate grade, and technical grade, supporting customers in the food and beverage, pharmaceutical, animal nutrition, dietary supplement, and personal care industries.
