PRODUCT INTRODUCTION

description

L-valine is the L-enantiomer of valine. It has a role as a nutraceutical, a micronutrient, a human metabolite, an algal metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a pyruvate family amino acid, a proteinogenic amino acid, a valine and a L-alpha-amino acid. It is a conjugate base of a L-valinium. It is a conjugate acid of a L-valinate. It is an enantiomer of a D-valine. It is a tautomer of a L-valine zwitterion.
