Metabolite Identification

Common Name

D-Malic acid

Description

D-Malic acid, also known as D-malate, belongs to the class of organic compounds known as beta hydroxy acids and derivatives. Beta hydroxy acids and derivatives are compounds containing a carboxylic acid substituted with a hydroxyl group on the C3 carbon atom. D-Malic acid exists in all living organisms, ranging from bacteria to humans. D-Malic acid is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on D-Malic acid.
