摘要：

The interactions of D- and L-enantiomers of polylysine with pectate and alginates with high contents of L-guluronate and D-mannuronate, respectively, were studied by means of circular dichroism (CD). L-guluronate arrangement that does not enter the complexation with poly(L-lysine) interacts with poly(D-lysine) very weakly. D-galacturonate arrangement interacting with poly(L-lysine) effectively, interacts with poly(D-lysine) only weakly. D-mannuronate arrangement interacting weakly with poly(L-lysine) enters the complexation with poly(D-lysine) effectively. On the basis of such enantioselectivity the handedness of the natural polysaccharide conformation may be deduced.
