Metabolite Identification

Common Name

L-2-Amino-3-(1-pyrazolyl)propanoic acid

Description

L-2-Amino-3-(1-pyrazolyl)propanoic acid, also known as beta-(pyrazole-1-yl)-L-alanine or alpha-amino-1H-pyrazole-1-propanoic 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). L-2-Amino-3-(1-pyrazolyl)propanoic acid has been detected, but not quantified in, fruits. This could make L-2-amino-3-(1-pyrazolyl)propanoic acid a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on L-2-Amino-3-(1-pyrazolyl)propanoic acid.
