Molecular structure of poly-L-lysine, lauric acid, and lauryl-poly-L-lysine. -Poly-L-lysine (-PLL) was built with the lysyl residue with linkages between the -carboxyl and -amino groups. The lysyl pattern was repeated (). The lauric acid was C12H24O2, called dodecanoic acid. The lauric acid was linked to PLL in random fashion.
