Phenylacetic acid

Identification

Name
Phenylacetic acid
Accession Number
DB09269
Description

Phenylacetic acid is an organic compound containing a phenyl functional group and a carboxylic acid functional group. It is a white solid with a disagreeable odor. Because it is used in the illicit production of phenylacetone (used in the manufacture of substituted amphetamines), it is subject to controls in countries including the United States and China.

Metabolism

Phenylacetate esterases found in the human liver cytosol. Human plasma esterase also hydrolyze phenylacetate. Phenylacetate hydrolysis involved arylesterase in plasma, both arylesterase and carboxylesterase in liver microsomes and carboxylesterase in liver cytosol. Plasma hydrolysis is less important and overall esterase activity is lower in humans than in the rat.
