N-(β-Carboxyethyl)-α-isoleucine

Abstract

The title compound, {2-[(2-carbamoylethyl)amino]-3-methylpentanoic acid}, C9H18N2O3, is of interest with respect to its biological activity. It was formed during an addition reaction between acrylamide and the amino acid isoleucine. The crystal structure is a three-dimensional network built up by intermolecular N—H...O and O—H...N hydrogen bonds.
