Identification
Common Name2-Hydroxyadipic acid
ClassSmall Molecule
Description2-Hydroxyadipic acid is a hydroxy-dicarboxylic acid formed by the reduction of 2-ketoadipic acid. Deficiency of 2-ketoadipic dehydrogenase causes 2-ketoadipic acidemia (OMIM 245130), a condition characterized by accumulation and excretion of 2-hydroxyadipic acid (with 2-ketoadipic and 2-aminoadipic) probably without adverse phenotypic effects.(OMMBID - The Metabolic and Molecular Bases of Inherited Disease, CH.95). A method involving derivatization and combined gas chromatography--mass spectrometry has been recently developed to separate the enantiomers of 3-hydroxyadipic acid It has been shown that 3-hydroxyadipic acid excreted in urine consists of at least 95% of the L-enantiomer. This finding supports the hypothesis that dicarboxylic acids are degraded by ordinary beta-oxidation, and indicates that adipic acid may be converted into succinic acid. (1, 1).

Mechanism of Toxicity2-Hydroxyadipic acid is a hydroxy-dicarboxylic acid formed by the reduction of 2-ketoadipic acid. Deficiency of 2-ketoadipic dehydrogenase causes 2-ketoadipic acidemia, a condition characterized by accumulation and excretion of 2-hydroxyadipic acid (with 2-ketoadipic and 2-aminoadipic) probably without adverse phenotypic effects.
