What is 3-(2-HYDROXYPHENYL)PROPIONIC ACID?

The Uses of 3-(2-HYDROXYPHENYL)PROPIONIC ACID

3-(2-Hydroxyphenyl)propionic acid is suitable as a growth substrate for various strains of E. coli and as a standard in the study of microbial metabolism of catechin stereoisomers.

Definition

ChEBI: A monocarboxylic acid that is propionic acid in which one of the hydrogens at position 3 is substituted by a 2-hydroxyphenyl group.

General Description

3-(2-Hydroxyphenyl) propionic acid is a phenyl propionic acid derivative. It was found to be one of the constituents of Justicia pectoralis Jacq. extract which was analyzed by gas chromatography/mass spectrometry (GC/MS). The antiulcerogenic effect of 3-(2-hydroxyphenyl) propionic acid in the prevention of serotonin-induced ulcerogenesis has been studied in rats. It has been reported to be one of the major microbial metabolite of both (+)-catechin and (-)-epicatechin by human faecal microbiota. Crystal structure study reveals that 3-(2-hydroxyphenyl)propionic acid crystals are monoclinic with space group P2₁/c.
