IPA: /ˈpɒliˌlaɪsiːn/
KK: /pɑːliˈlaɪsiːn/
A type of protein made up entirely of lysine amino acids.
Polylysine is often used in biochemistry for its ability to bind to negatively charged surfaces.
Polylysine → It is formed from "poly-" (from Greek "polus", meaning many) and "lysine" (from Greek "lysine", meaning to loosen or dissolve). The word "polylysine" refers to a compound made up of many lysine units, which are amino acids that can help in various biological functions.
Think of 'many' ('poly-') lysine units coming together to form a compound — that's what polylysine means.
