Abstract
Ordered conformations from the sodium salts of chondroitin 4-sulphate, dermatan sulphate and heparan sulphate were observed by X-ray diffraction. Chondroitin 4-sulphate shows similar threefold helical character to that previously reported for chondroitin 6-sulphate and hyaluronates. Dermatan sulphate forms an eightfold helix with an axial rise per disaccharide of 0.93nm, which favours the l-iduronic acid moiety in the normal C1 chair form. The layer-line spacing and axial projection in heparan sulphate of 1.86nm favours a tetrasaccharide repeat with glycosidic linkages alternating beta-d-(1-->4) and alpha-d-(1-->4).Keywords
