Polylysine bụ polymer mejupụtara lysine monomers, nke a na-ahụkarị n'ụdị eke ma ọ bụ sịntetik. Ọ nwere ngwa dị iche iche, gụnyere na ụlọ ọrụ nri, ọgwụ na biotechnology.
Polylysine (ε-poly-L-lysine, EPL) bụ obere homopolymer sitere n'okike nke amino acid L-lysine dị mkpa nke emepụtara site na ya.
nje gbaa ụka. A na-eji ε-Poly-L-lysine mee ihe dị ka ihe nchekwa eke na ngwaahịa nri.ε-Polysine bụ nke otu polymer cationic. N'ime mmiri, ε-polysine nwere otu amino acid hydrophilic na-akwụ ụgwọ nke ọma. Dị ka nchọpụta si kwuo, ε-polylysine na-agbanye electrostatically n'elu cell nke nje bacteria, na-esote nke a na-ewepụ akpụkpọ ahụ dị n'èzí.
ε-Polysine a ghọtara dị ka ihe dị oke nchebe na obodo sayensị. ε-Polysine n'ozuzu ghọtara dị ka nchekwa dị ka nri na-echekwa nri na October, 2003. A kwadoro ya ka ọ bụrụ ihe na-egbochi nje na osikapa esi ya ma ọ bụ sushi osikapa na ọkwa ruo 50 milligrams kwa kilogram (mg/kg) osikapa. Nsonaazụ nke nnukwu toxicity ọmụmụ na nje bacteria maka mutagenicity na-egosi na ε-Polysine abụghị ihe na-egbu egbu ma ọ dịghị ihe akaebe maka ọrụ mutagenic nke ε-Polysine. Ya mere ε-Polysine dị nnọọ mma iji mee ihe dị ka ihe nchekwa nri.
