What is L-Valine?

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