产品应用

• 卡拉胶是阴离子型线状的多聚体，每个二糖类单元由带有一个(κ-), 2个(ι-) 或3个(λ-) 硫酸根的1,3α-1,4β-半乳聚糖组成。在离子溶液中，κ- 和 ι-卡拉胶缠绕成螺旋状结构，形成坚固或柔韧的胶体，而λ-卡拉胶不形成螺旋结构，不构成胶体部分，卡拉胶常用作增稠剂和稳定剂。

其他信息

• 卡拉胶是从红藻类的细胞壁中提取的粘多糖。它们是阴离子的线型聚合物，是由具有一个（κ），两个（ι）或三个（λ）硫酸盐的二糖单元的α-1，1,3，4β-半乳聚糖组成。在离子溶液中，κ-和ι-角叉菜胶成螺旋结构的自交联，从而形成刚性或柔性凝胶， λ-角叉菜胶不形成螺旋，属非凝胶。角叉菜胶作为增稠剂和稳定剂是用于商业化。
