Raman spectroscopic studies of pig skin proteodermatan sulfate in H 2 O are indicative of a well defined secondary structure consisting of α‐helical, β‐turn, and possibly “random” structures. The above conclusion is surprisingly close to the secondary structure of the “core” protein of pig skin proteodermatan sulfate proposed in the previous paper (V. Renugopalakrishnan et al., Biopolymers 28 , 1923–1933, 1989) from FT‐IR and CD spectroscopic studies in aqueous solution.
