一、CSA的来源与化学概况 1861年Fiseher 第一次报告了硫酸软骨素A,1891年Schmiederberg从鼻软骨中分离出来。 CSA是由己糖醛酸与半乳糖胺通过β,1-3糖甙键结合的双糖为基本单位聚合成的大分子聚多糖,比较广泛地存在鱼类、家禽、哺乳动物和人体的结缔组织和软骨组织中。同时,也是哺乳动物血液、动脉血管组织内的主要成分。在动脉组织的CSA量与其它酸性粘多糖含量的比例常伴随着年龄的增长和动脉粥样硬变而有所降低。据报导,CSA还有类
First, the source and chemical profiles of CSA Fiseher first reported in 1861 chondroitin sulfate A, 1891 Schmiederberg isolated from the nasal cartilage. CSA is a macromolecular polysaccharide polymerized from hexasaccharide acid and galactosamine through the β, 1-3 glycosidic bond disaccharide as the basic unit. CSA is more widely distributed in fish, poultry, mammals and human connective tissue And cartilage tissue. At the same time, it is also a major component of mammalian blood and arterial tissue. The ratio of CSA in arterial tissue to other acidic mucopolysaccharides often decreases with age and atherosclerosis. It is reported that CSA still has a class
