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。
不溶于热浓缩的盐溶液
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。
可被用于基于凝胶中细胞生长的微生物细胞的固定化

Carrageenans obtained from seaweeds can be processed into films for a range of applications including food packaging. The level of carrageenan refinement during extraction can influence the key properties, with semi-refined carrageenan (SRC) containing more impurities than the more refined
The hydrophobic modification of kappa carrageenan microgel particles for the stabilisation of foams.

Journal of colloid and interface science, 538, 165-173 (2018-12-05)
Polysaccharides such as kappa carrageenan are often utilised in fat replacement techniques in the food industry. However, the structural role they can provide within a product is limited by their hydrophilic nature. Hydrophilic particles can be surface-activated by hydrophobic modification
