PRODUCT INTRODUCTION
description
Phenylacetic acid is a monocarboxylic acid that is toluene in which one of the hydrogens of the methyl group has been replaced by a carboxy group. It has a role as a toxin, a human metabolite, an Escherichia coli metabolite, a plant metabolite, a Saccharomyces cerevisiae metabolite, an EC 6.4.1.1 (pyruvate carboxylase) inhibitor, an Aspergillus metabolite, a plant growth retardant, an allergen and an auxin. It is a monocarboxylic acid, a member of benzenes and a member of phenylacetic acids. It is functionally related to an acetic acid. It is a conjugate acid of a phenylacetate.
