Biological Activity
| ln Vitro | D-lysine is created from L-lysine through continuous chemical racemization and microbial asymmetric breakdown. L-lysine is the enantiomer of D-lysine. D-Lysine is found in all species from bacteria to humans. D-Lysine is a potentially hazardous chemical [1]. |

| Additional Infomation |
Lysine is a diamino acid that is caproic (hexanoic) acid bearing two amino substituents at positions 2 and 6. It has a role as a Daphnia magna metabolite. It is an alpha-amino acid, a diamino acid and a polar amino acid. It contains a 4-aminobutyl group. It is functionally related to a hexanoic acid. It is a conjugate base of a lysinium(1+). It is a conjugate acid of a lysinate. DL-Lysine has been reported in Drosophila melanogaster, Enterococcus faecalis, and other organisms with data available.
