Amylose selectively includes poly( L ‐lactide) (PLLA) among the poly(lactide)s (PLAs) to produce an inclusion complex when the phosphorylase‐catalyzed polymerization of α‐ D ‐glucose 1‐phosphate is performed in the presence of PLLA, poly( D ‐lactide) (PDLA), or poly( DL ‐lactide) (PDLLA) (vine‐twining polymerization). This result indicates that amylose recognizes the chirality in PLAs on the formation of an inclusion complex in vine‐twining polymerization. Modeling calculations support the amylose's chiral recognition in favor of PLLA and the atomistic details of the inclusion complex which involved the preferred orientation of the constituent molecular chains with respect to their fiber axis is proposed.
