Common Name | 3-Hydroxymandelic acid |
---|
Description | 3-Hydroxymandelic acid, also known as m-hydroxymandelate or MHMA, is a 2-hydroxy monocarboxylic acid. 3-Hydroxymandelic acid is the dehydroxylated (positions 2 and 3’) derivative of phenylacetic acid. It is a white crystalline solid that is soluble in water and polar organic solvents. It derives from a mandelic acid. Mandelic acid is a substrate or product of several biochemical processes called the mandelate pathway. Mandelate racemase interconverts the two enantiomers via a pathway that involves cleavage of the alpha-CH bond. Mandelate dehydrogenase is yet another enzyme on this pathway. Mandelate also arises from trans-cinnamate via phenylacetic acid, which is hydroxylated. Derivatives of mandelic acid, such as 3-hydroxymandelic acid, are formed as a result of metabolism of adrenaline and noradrenaline by monoamine oxidase and catechol-O-methyl transferase. |
