Chemical Information
Name(R)-3-Hydroxybutyric acid
Description(R)-3-Hydroxybutyric acid is a butyric acid substituted with a hydroxyl group in the beta or 3 position. It is involved in the synthesis and degradation of ketone bodies. Like the other ketone bodies (acetoacetate and acetone), levels of beta-hydroxybutyrate are raised in the blood and urine in ketosis. Beta-hydroxybutyrate is a typical partial-degradation product of branched-chain amino acids (primarily valine) released from muscle for hepatic and renal gluconeogenesis This acid is metabolized by 3-hydroxybutyrate dehydrogenase (catalyzes the oxidation of D-3-hydroxybutyrate to form acetoacetate, using NAD+ as an electron acceptor). The enzyme functions in nervous tissues and muscles, enabling the use of circulating hydroxybutyrate as a fuel. In the liver mitochondrial matrix, the enzyme can also catalyze the reverse reaction, a step in ketogenesis. 3-Hydroxybutyric acid is a chiral compound having two enantiomers, D-3-hydroxybutyric acid and L-3-hydroxybutyric acid. In humans, beta-hydroxybutyrate is synthesized in the liver from acetyl-CoA, and can be used as an energy source by the brain when blood glucose is low. It can also be used for the synthesis of biodegradable plastics . [HMDB]
