Chain conformations have been investigated theoretically by assuming Markoffian process for copolypeptides composed of two components of L-alanine, glycine, N-methyl glycine and N-methyl-L-alanine, for D.L-copolyalanine, and for D, L-copoly-N-methyl alanine. The characteristic ratio of these copolymers was plotted against the sequence probability that a residue is followed by a residue of the same kind. Some experimental results obtained for equimolar-D, L-copoly-γ-methyl glutamate are discussed with the aid of theoretical equation
