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。
