Polylysine

Polylysine (ε-poly-L-lysine, EPL) is a small natural homopolymer of the essential amino acid L-lysine that is produced by bacterial fermentation. ε-Poly-L-lysine is used as a natural preservative in food products. ==Chemical structure & function== ε-Polylysine is typically produced as a homo-polypeptide of approximately 25-30 L-lysine residues....
