Define about the Ascorbic acid (vitamin C)?

Ascorbic acid was discovered as the anti-scurvy vitamin. Vitamin C (chemical names ascorbic acid and ascorbate) is the six-carbon lactone of α-keto-L-gulonic acid. It is, infect, a derivative of carbohydrate. It is closely related to monosaccharide sugars in its structure. Vitamin C is synthesized in the liver in some mammals and in the kidney in birds and reptiles. However, humans are unable to synthesize vitamin C. Hence, when there is insufficient vitamin c in the diet, humans suffer from the potentially lethal deficiency disease-scurvy.
