Metabolite Identification
Common Name2-Phenylglycine
Description2-Phenylglycine, also known as a-amino-a-toluate or L-PHG amino acid, belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). 2-Phenylglycine exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule.
