Metabolite Identification
Common Name(S)-Abscisic acid
Description(S)-(+)-Abscisic acid, also known as abscisic acid or (S)-abscisate, belongs to the class of organic compounds known as abscisic acids and derivatives. These are terpene compounds containing the abscisic acid moiety, which is characterized by a 3-methylpenta-2,4-dienoic acid attached to the C1 carbon of a 4-oxocyclohex-2-ene moiety (S)-(+)-Abscisic acid exists as a solid and is considered to be practically insoluble (in water) and relatively neutral. Within the cell, (S)-(+)-abscisic acid is primarily located in the cytoplasm and membrane (predicted from logP) (S)-(+)-Abscisic acid can be converted into (S)-2-trans-abscisic acid D-glucopyranosyl ester and (S)-2-trans-abscisic acid beta-D-glucopyranosyl ester. Outside of the human body, (S)-(+)-abscisic acid can be found in a number of food items such as common pea, garden tomato (var.), brassicas, and yellow wax bean. This makes (S)-(+)-abscisic acid a potential biomarker for the consumption of these food products.
