Low molecular weight heparins (LMWHs) are important anticoagulant drugs. Nitrous acid degradation is a major approach to produce LMWHs, such as dalteparin. Due to the foreseeable shortage of porcine intestinal mucosa heparin and other potential risks, expansion of other animal tissues for heparin preparation is necessary. Heparins from different tissues differ in structure and bioactivity potency,...
Low molecular weight heparins (LMWHs) are widely used anticoagulant drugs. The composition and sequence of LMWH oligosaccharides determine their safety and efficacy. The short oligosaccharide pool in LMWHs undergoes more depolymerization reactions than the longer chains and is the most sensitive indicator of the manufacturing process. Electrospray ionization tandem mass spectrometry (ESI–MS/MS) has...
