Abstract

Polycondensation of octadecyl esters of aromatic amino acids (L-TrpC18, L-TyrC18, L-PheC18) can be markedly accelerated in the monolayers on the aqueous subphase of pH 8. The reaction rate was ten times or more faster than in the bulk solid. There exist optimum molecular packing and orientation for the polycondensation. The resultant poly-ammo acids take α-helix and/or random coil conformations.
