WebMay 1, 2013 · The increase in temperature induces the formation of β structures. The obtained assignment of the infrared bands for various conformations was used to determine the conformational populations of PLL in non-aqueous solvents. In TFE, PLL possesses an α-helix structure that is after heating partially transformed into the P II conformation. 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.
