一般描述
角叉菜胶是来自红藻细胞壁的粘多糖。 它们是由1,3α-1,4β-半乳聚糖组成的阴离子线性聚合物，每个二糖单元具有一个（κ-）、两个（ι-）或三个（λ-）硫酸根。 在离子溶液中，κ-和ι-角叉菜胶自缔合成螺旋结构，分别形成刚性或柔性凝胶。 λ-角叉菜胶不形成螺旋，并且不凝胶化。 角叉菜胶在商业上用作增稠剂和稳定剂。
应用
角叉菜胶被用于在体内和体外实验中抑制通过巨噬细胞选择性细胞病变效应机制而产生的免疫应答。 由于ι-、κ-和λ-角叉菜胶具有不同程度的硫酸化，因此可以对它们在保护性、抗病毒性和免疫抑制活性方面的差异进行比较研究。

The sulfated polysaccharide (PLS) fraction of Agardhiella ramosissima was characterized by microanalysis, infrared spectroscopy, NMR and gas-liquid-chromatography-mass-spectrometry. The main constituent of PLS was the ι carrageenan. The monosaccharide composition of the PLS showed galactose, 3,6-anhydrogalactose and 6-O-methylgalactose. The PLS (30

Sulfatases play a biologically important role by cleaving sulfate groups from molecules. They can be identified on the basis of signature sequences within their primary structures, and the largest family, S1, has predictable features that contribute specifically to the recognition
