L-Lysine 56-87-1 is an essential amino acid, lysine is not synthesized in animals, hence it must be ingested as lysine or lysine-containing proteins. In plants and most bacteria, it is synthesized from aspartic acid. Lysine is a base, as are arginine and histidine. The ε-amino group often participates in hydrogen bonding and as a general base in catalysis. The ε-amino group is attached to the fifth carbon from the α-carbon, which is attached to the carboxyl group.
