L-Lysine is an essential proteinogenic α amino acid. It contains an N-butyl amino group in the side chain, and this moiety is protonated at physiological pH. In addition, L-lysine is one of the two amino acids that are degraded to give ketone bodies (a ketogenic amino acid).


L-Lysine is used in a wide range of applications including as a supplement in cell culture media; a substrate of enzymes such as L-lysine oxidase (EC 1.4.3.14); a component of poly-lysine polymers; and a substrate for oxidation and glycation mechanism studies. L-lysine has been used with cultured human osteoblasts to study cell proliferation.


Lysine is degraded in vivo to give acetoacetyl CoA via an initial transamination with alpha-ketoglutarate.
