(S)-(+)-2-Hydroxy-3-methylbutyric acid

Description:
(S)-(+)-2-Hydroxy-3-methylbutyric acid, also known as HMB (beta-hydroxy-beta-methylbutyrate), is a branched-chain fatty acid derivative that is commonly studied for its potential benefits in muscle metabolism and recovery. It is a chiral compound, existing in two enantiomeric forms, with the (S)-enantiomer being the biologically active form. This compound is typically a white crystalline solid at room temperature and is soluble in water, which facilitates its absorption in biological systems. HMB is produced naturally in the body from the amino acid leucine and is often used as a dietary supplement, particularly among athletes and individuals engaged in resistance training, due to its purported effects on muscle mass and strength. In terms of chemical properties, it has a carboxylic acid functional group, contributing to its acidity and reactivity. HMB is generally regarded as safe when consumed in recommended amounts, although excessive intake may lead to gastrointestinal discomfort. Its role in protein metabolism and potential anti-catabolic effects make it a subject of ongoing research in sports nutrition and health.
