PRODUCT INTRODUCTION
description
L-lysine is an L-alpha-amino acid; the L-isomer of lysine. It has a role as a micronutrient, a nutraceutical, an anticonvulsant, an Escherichia coli metabolite, a Saccharomyces cerevisiae metabolite, a plant metabolite, a human metabolite, an algal metabolite and a mouse metabolite. It is an aspartate family amino acid, a proteinogenic amino acid, a lysine and a L-alpha-amino acid. It is a conjugate base of a L-lysinium(1+). It is a conjugate acid of a L-lysinate. It is an enantiomer of a D-lysine. It is a tautomer of a L-lysine zwitterion and a L-Lysine zwitterion.
