Results of infrared spectroscopy of complexes between cations and heparins, heparans and chemically-modified polymers suggest the existence of two conformational forms of heparins/heparans, differing in their modes of interaction with cations. Functions of heparans at normal and cancer cell surfaces are discussed in the light of this model.
