Ascorbic Acid(Vitamin C):-

            Vitamin C is an essential nutrient for humans and certain other animal species, in which it functions as a vitamin. In living organisms, it is an antioxidant, since it protects the body against oxidative stress. It acts as a reducing agent to reverse oxidation in liquids. Scurvy is an avitaminosis resulting from lack of vitamin C, since without this vitamin, the synthesised collagen is too unstable to perform its function. Ascorbic acid performs numerous physiological functions in the human body which includes the synthesis of collagen, carnitine, and neurotransmitters; the synthesis and catabolism of tyrosine; and the metabolism of microsome.
