This book describes the complex structures of heparins and heparan sulfates (heparinoids) and how they are generated by their biosynthetic pathways. The book also details the methodologies for studying these structures and their cellular metabolism. Heparin-Binding Proteins introduces the general nature of interactions between heparinoids and proteins, and presents the role for these structures in their interactions with the proteins of the hemostatic mechanisms, fibroblasts growth factors, superoxide dismutase, and lipoproteins.
