一般說明
抗坏血酸,也称为维生素C,是由植物和一些动物物种(不包括人类和其他灵长类动物)产生的六碳内酯。它是一种水溶性维生素。
應用
L-抗坏血酸可作为标准品测定过氧自由基介导的红细胞溶血。它可用于还原氧化石墨烯片。
L-抗坏血酸已用作高效液相色谱法测定 L-抗坏血酸的标准品。
生化/生理作用
L-抗坏血酸改性聚酯氨酯可能会促进软组织再生。它还有助于增加组织对铁的吸收。另外,它有助于酪氨酸代谢和微粒体药物代谢。
L-抗坏血酸是一种抗氧化剂。L-抗坏血酸(维生素C)对于许多酶反应十分重要,可保持其金属离子辅因子的还原形式(例如Fe2+、Cu+)。它通过清除自由基保护组织免遭氧化损伤。它具有较强的还原能力且无毒性,在实验中常用作还原剂。有报道使用磷钨酸通过比色法测定抗坏血酸。
