lysine

 [li´sēn]
a naturally occurring amino acid, one of those essential for human metabolism, necessary for optimal growth in human infants and for maintenance of nitrogen equilibrium in adults. The acetate and hydrochloride salts are used for dietary supplementation and the hydrochloride salt is used for the treatment of severe metabolic acidosis refractory to other treatment.

(lī'sēn),
2,6-Diaminohexanoic acid; the l-isomer is a nutritionally essential α-amino acid of mammals found in many proteins; distinguished by an ε-amino group.
