A-hb - a hydroxy fatty acid anion and conjugate base of 2-hydroxybutyric acid. 2-hydroxybutyrate is a metabolite produced by the conversion of cystathionine to cysteine in the glutathione biosynthesis pathway. The amount of 2-hydroxybutyrate secreted in the urine can reflect changes in the rate of glutathione synthesis, which is altered by oxidative stress or toxin exposure. Also see 2-hydroxybutyrate
