a肝素是从哺乳动物组织中提取的硫酸化的糖胺聚糖类化合物,一般产品为其钠盐或钙盐。 The heparin is the sulphating osamine which withdraws from the mammal organization gathers the carbohydrate compound, common product for its sodium salt or calcium salt.[translate]...
Heparin is extracted from intestinal brine, i.e., from the brine which results from the preservation and dewatering treatment of animal tissue with sodium chloride, using conventional methods. The extracted product has a high activity and can subsequently be further purified to yield very high ...
youdao 26. This is a precursor to heparin, an important anti-clotting agent that has, at present, to be extracted from blood, rather than being synthesised. 这是肝磷脂的初期形态,一种重要的抗凝固剂,目前要获得该物质就不得不从血液中提取,而不是人工合成。 youdao热门...

Heparin is an unusual drug. It is a heterogenous, polydisperse sulphated polysaccharide extracted from hog or cattle intestinal mucous lining, where it is found in the granules of mast cells [1]. It is a member of the class of anionic polysaccharides known as glycosaminoglycans (GAGs). Heparin...
The ability of sulfated polysaccharides to interfere with biological systems has been illustrated withheparin, which is a highly sulfated polysaccharide widely used for anticoagulant therapy. As a sulfated polysaccharide extracted from brown seaweeds, fucoidan demonstrated excellent anticoagulant activity and hu...
and is a natural anticoagulant substance in animals. Naturally present in mast cells, it is now mainly extracted from bovine lung or small intestinal mucosa. As an anticoagulant, it is a multimer composed of two polysaccharides alternately linked to each other and has anticoagulant effects in vivo...
Unfractionated heparin is a heterogeneous mixture of polysaccharides and glycosaminoglycuronsulfate which for commercial preparations is generally extracted from bovine and sheep lungs and porcine intestinal mucosa. Low-molecular-weight heparins are fragments of unfractionated heparin produced by controlled ...
In the case of most low-molecular-weight heparins, the heparin is extracted from pig mucosa, and the principal tetrasaccharides are represented below. These tetrasaccharides are resistant to enzymatic depolymerization and comprise the sequences with affinity for antithrombin III. These tetrasaccharides ...
The heparin is mainly extracted from animal tissues and organs such as bovine lung and porcine intestinal mucosa. However, besides low safety, low yield, large solvent consumption, and severe environmental pollution, the natural extraction method introduces impurity contamination (such as chondroitin sulf...
