Heparin is a linear sulphated polysaccharide comprising contiguous disaccharide units of a uronic acid and a derivative of 2-amino-2-deoxy-D-glucose. The heparin tetrasaccharide can be obtained from the degradation of heparin with the lyase enzymes isolated from Flavobacterium heparinum, which yields oligosaccharides terminated at the non-reducing end by the unsaturated unit, 4-deoxy-alpha-L-threo-hex-4-enopyranosyl uronic acid or its 2-0-sulphated derivative. The major product following lyase degradation is the trisulphated derivative DUA-2S + GlcNS-6S (unsaturated disaccharide). Synonyms: Tetrasaccharide (dp4) CAS No: 61844-85-7 Appearance: White to yellow powder Purity: 75% Storage and Stability: May be stored at 4C for short-term only.
