角质素硫酸
中文名称
通路描述
角质素硫酸(KS)是一种糖胺聚糖,其基本二糖单元为N-乙酰乳糖胺,Gal(b1-4)GlcNAc(b1-3),并在GlcNAc和Gal残基的C-6位上带有硫酸酯。存在两种类型的KS,根据蛋白连接方式区分:类型I通过N-糖苷键连接至N-糖苷核心结构,类型II通过O-糖苷键连接至O-糖苷核心2结构。
英文描述
Keratan sulfate (KS) is a glycosaminoglycan with the basic disaccharide unit of N-acetyllactosamine, Gal(b1-4)GlcNAc(b1-3), with sulfate esters at C-6 of GlcNAc and Gal residues. There are two types of KS distinguished by the protein linkage: type I for N-linked via the N-glycan core structure and type II for O-linked via the O-glycan core 2 structure.
