WebSep 27, 2024 · Poly(L-lysine) as the Core of Micelles. Poly(L-lysine) is positively charged and water-soluble, containing a lot of amino groups. Theoretically, poly(L-lysine) is difficult to form the core of micelles because of the poor hydrophobicity. However, there are several ways to assist polylysine in constructing the micellar core. The precursor amino acid lysine contains two amino groups, one at the α-carbon and one at the ε-carbon. Either can be the location of polymerization, resulting in α-polylysine or ε-polylysine. Polylysine is a homopolypeptide belonging to the group of cationic polymers: at pH 7, polylysine contains a positively charged hydrophilic amino group. α-Polylysine is a synthetic polymer, which can be composed of either L-lysine or D-lysine.
