一种从海藻类植物-海带中提出的亲水性多糖。几乎无臭无味。对湿敏感。缓溶于水，形成黏稠胶体状溶液，不溶于乙醇、乙醚和氯仿及pH值低于3的酸中。溶液加热不凝结。 分子量结构单位：理论值198.11，平均真实值222.00稳定剂。增稠剂。作人造半透膜。媒染剂。 生化级用于固定细胞、酶；如海藻酸钠法固定化谷氨酸脱羧酶。海藻酸基质可以通过添加螯合剂而液化。

Alginic acid sodium is a gelling and nontoxic anionic polysaccharide. The carboxylic acid groups on the alginic acid chain, renders it insoluble in water.However, converting alginic acid to its sodium form, enables it to solubilize in water easily.
Alginic acid sodium is used: in combination with chitosan, to fabricate a biodegradable porous scaffold for bone tissue engineering. to study the characteristics of a modified amphiphilic alginate derivative to the study the impact of alginate on the rate of lipid digestion by employing an in vitro digestion model in the preparation of alginate hydrogels as encapsulating agents of microparticles of β-galactosidae
