Information of High Purity Lactic Acid
The structural formula of lactic acid is CH3CHOHCOOH, the molecular formula C3H6O3, the relative molecular mass is 90.08, and the molecule has both hydroxyl (OH) and carboxyl (COOH) functional groups. It is the most widely existed hydroxycarboxylic acid in nature and the simplest one. Hydroxamic acid. Lactic acid is widely present in animals, plants, and microorganisms. L-lactic acid and L-lactate dehydrogenase capable of metabolizing L-lactic acid are present in tissues of humans and animals, and D-lactate dehydrogenase is absent. The human body ingests L lactic acid, which can be absorbed and decomposed, while D lactic acid can not be decomposed, and it is easy to form D lactic acid enrichment in the body.
