说明

L-抗坏血酸是维生素C最具生物活性的形式。它是一种亲水性和不稳定的化合物。L-抗坏血酸含有一种六碳内酯，由植物和一些动物物种产生，但不由人类和其他灵长类动物产生。抗坏血酸，也称为维生素C，是一种水溶性维生素。抗坏血酸带有中性电荷，通过质子化转化为抗坏血酸钠。维生素C是柑橘类水果的一部分，如花椰菜、草莓、萝卜。
L-抗坏血酸根据其氧化还原性质发挥作用。它是羟基化的辅因子。L-抗坏血酸的生化作用取决于单氧化酶的活性。它参与肉碱、胶原蛋白合成和神经递质的产生。维生素C具有抗氧化特性。维生素C在防止光老化和抗衰老方面发挥作用。维生素C缺乏会导致坏血病、牙龈出血、伤口愈合不良、贫血和肌肉退化。

一般描述

L-Ascorbic acid is the most biologically active form of ascorbic acid. It is hydrophilic and an unstable compound. L-Ascorbic acid contains a six-carbon lactone produced by plants and some animal species but not by humans and other primates. Ascorbic acid, also referred to as Vitamin C, is a water-soluble vitamin. Ascorbic acid carries a neutral charge, which gets converted to ascorbate by protonation. Vitamin C is a part of citrus fruits, such as broccoli, strawberries, turnip.
 

生化/生理作用

L-Ascorbic acid functions according to its oxido-reduction property. It is a co-factor for hydroxylation. The biochemical actions of L-ascorbic acid is dependent on the activity of monoxygenase. It is involved in carnitine, collagen synthesis and production of neurotransmitters. Vitamin C exhibits anti-oxidant properties. Vitamin C plays a role in providing protection against photoaging and anti-aging effect. Deficiency of vitamin C leads to scurvy, bleeding gums, poor wound healing, anemia and muscle degeneration.
Ascorbic Acid, also known as Vitamin C, is a six-carbon lactone produced by plants and some animal species but not by humans and other primates.
