Heparin

High grade unfractionated Heparin is a glycosaminoglycan polymer with a high degree of sulfation. Although the main disaccharide in heparin is the trisulphated unit GlcNS,6S – IdoA,2S heparin also contains di-, mono- and non-sulphated units; thus each size class of oligosaccharide, though substantially homogeneous in molecular size, contains structures that vary in content and pattern of sulphation.
