Epsilon-polylysine CAS 28211-04-3

ε-Polylysine is a light yellow powder, hygroscopic, slightly bitter taste, is a straight chain polymer of lysine, it is produced by the fermentation of Streptomyces, with a broad-spectrum bacteriostatic effect. ε-Polylysine is polymerized by the Chemicalbook 25-30 lysine groups, it is more stable to ph, heat, and the bacteriostatic effect of its degree of polymerization and the environment is related to the molecular weight of 3600-4300 between the best inhibitory activity. The molecular weight between 3600-4300 is the best antibacterial activity.
