Abstract
The relation of the chemical structure of heparin to its anticoagulant activity has been of interest for many years (4, 8, 11), and much information has accumulated on it. However, study of this has been complicated by the variability in composition of heparin (1) and by its chemical similarity to some other mucopolysaccharides with which it is often associated in tissues. It is now possible to isolate heparin that is nearly free of contaminating polysaccharides and has high biologic activity, but this was not always so. Thus, some of the early reports of the effects of molecular size or sulfate concentration on biologic activity are difficult to assess. Because earlier preparations generally had lower and more variable anticoagulant activity than current ones, conflicting reports of the relation of various characteristics to biologic activity have appeared, and the problem is made more difficult by the lack of full knowledge of the chemical structure of heparin and by the complexity of its possible structural arrangements.
