一般描述

L-抗坏血酸用作食品添加剂、褐变抑制剂、风味稳定剂、面团改良剂和颜色稳定剂。坏血病与抗坏血酸缺乏相关。L-抗坏血酸可刺激免疫反应,并参与胶原、肉碱和神经递质合成。

应用

L-抗坏血酸已用于:
  • 作为成骨分化培养基中的一种成分
  • 作为分化骨髓基质细胞的MesenCult培养基组分
  • 作为维生素C测定的标准品
  • 防止三氯甲烷生成势(THMFP)

生化/生理作用

L-抗坏血酸(L-AA)是一种可广泛获取的水溶性化合物。L-AA具有抑制低碳钢腐蚀的能力。
抗坏血酸,也称为维生素C,是由植物和一些动物物种产生的六碳内酯,但人类和其他灵长类动物不能产生。抗坏血酸作为多种酶的酶促辅助因子发挥作用,用作单加氧酶和双加氧酶的电子供体。抗坏血酸也是一种强大的抗氧化剂,尤其是对活性氧类。
