Ascorbic Acid Ascorbic acid is a reduced form of vitamin C synthesised from hexose sugar. Chemically, the vitamin occurs in 3 isomeric forms viz. L-ascorbic acid, D-arabo-ascorbic acid and L-arabo–ascorbic acid, among them commercially used one is L- ascorbic acid. Ascorbic acid is synthe...

1). Ascorbate is an excellent reducing agent and readily undergoes two consecutive, one-electron oxidations to form ascorbate radical (Asc−) and dehydroascorbic acid (DHA). The ascorbate radical is relatively unreactive due to resonance stabilization of the unpaired electron; it readily dismutes ...
Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin. Unlike most mammals and other animals, humans do not have the ability to synthesize vitamin C and must obtain it from the diet. 维生素 C,也称为 L-抗坏血酸,是一种水溶性维生素。与大多数哺乳动物和其他动物不同,人类没...
L-ascorbic acid mainly protects from hydroxyl radicals, superoxide and singlet oxygen. In addition, it also reduces the membrane-linked antioxidant α-tocopherol (oxidised form). L-Ascorbic acid enhances endothelium-dependent vasodilation in various disorders, including diabetes, coronary artery disease, ...
In a solution of 5% metaphosphoric acid/0.6% sulfosalicylic acid, tissues were weighed and homogenized. The amount of total glutathione was calculated as µmmol/g tissue using a glutathione reductase and Nicotinamide Adenine Dinucleotide Phosphate(NADPH)-coupled reaction with 5, 50-dithiobis. AA ...
Stimulation of antioxidant systems with metabolic changes by signaling molecules such as ascorbic acid (AA) is a common stress tolerance strategy in plants and algae. The effect of AA on tolerance to long-term salinity of the green microalgaDunaliella salinawas investigated by studying biochemical cha...
L-Ascorbic Acid, also known as Vitamin C, is a vital compound for humans with antioxidant properties. It is prone to degradation of natural pigments in food and has low stability in water. AI generated definition based on: Journal of Functional Foods, 2021 ...
