一般說明

软骨素是一种糖胺聚糖(GAG)，是N-乙酰半乳糖胺(GalNAc)和葡萄糖醛酸(GlcA)交替单元组成的多糖链，可以在GalNAc和GlcA其中一个单元或两个单元上发生硫酸化。软骨素及其硫酸盐经常与蛋白质结合形成蛋白多糖。硫酸软骨素B（硫酸软骨素）是蛋白聚糖的组分，例如核心蛋白聚糖，双糖链蛋白聚糖和多功能蛋白聚糖。硫酸软骨素B用于研究 β 肽（1-42）的细胞毒性。

應用

硫酸软骨素B可用于研究其作为生物分子受体、细胞信号传导和细胞结合分子的介质的作用。它可用于与硫酸软骨A和硫酸软骨素C的性质进行比较。硫酸软骨素B用于研究 β 肽（1-42）的细胞毒性。

生化／生理作用

作为一种大的带负电荷亲水性分子，硫酸软骨素分子不足以灵活折叠成紧密的球状结构，而是形成多孔水合凝胶，为组织提供机械支持，并允许水溶性分子的快速扩散和细胞迁移。

成分

硫酸软骨素B是在软骨、皮肤、角膜和脐带中发现的酸性粘多糖。 它由交替的N-乙酰半乳糖胺，L-艾杜糖醛酸和等摩尔量的硫酸盐残基组成，其中N-乙酰半乳糖胺的4位碳被硫酸化。

注意

请将该产品储存在2-8°C。

One mechanism leading to neurodegeneration during Alzheimer's disease (AD) is amyloid beta peptide (Abeta)-induced neurotoxicity. Among the factors proposed to potentiate Abeta toxicity is its covalent modification through carbohydrate-derived advanced glycation endproducts (AGEs). Other experimental evidence, though, indicates that certain

Glycosaminoglycans and Proteoglycans

There are five identified glycosaminoglycan chains (see Figure 1): Hyaluronan is not sulfated, but the other glycosaminoglycan chains contain sulfate substituents at various positions of the chain.
