一般說明
L-抗坏血酸的生物合成途径在植物,动物和真菌中有所不同。在L-古洛糖酸-1,4-内酯氧化酶(GLO)的作用下,由L-古洛糖酸-1,4-内酯合成。
應用
L-抗坏血酸用于:
- 用作成软骨培养基成分,培养骨源性间充质干细胞(BMSC)(149)
- 用作高效液相色谱(HPLC)系统的参考标准品(150)
- 分析其对人类胃癌GES-1细胞和AGS细胞的影响(151)
生化/生理作用
L-抗坏血酸缺乏与L-古洛糖酸-1,4-内酯氧化酶(GLO)酶缺乏有关。能引起抗氧化作用,并通过抗坏血酸自由基中间体氧化为脱氢抗坏血酸。L-抗坏血酸对于维持氧化还原平衡至关重要。是多巴胺-β羟化酶的辅酶,有利于T细胞增殖,保护免疫系统,缓解普通感冒症状。
抗坏血酸,也被称为维生素C,是一种六碳内酯,由植物和一些动物产生,但是人和其他灵长类无法产生。抗坏血酸是多种酶的辅酶,可用作单加氧酶和双加氧酶的电子公里。抗坏血酸没还是强大的抗氧化剂,特别是对于活性氧化簇很有效。
