📗 Ascorbic acid also known as vitamin C. Vitamin C is Ascorbic acid also known as vitamin C. Vitamin C is very essential for growth and maintenance of the human body. It is necessary for the normal formation of protein collagen, which is an important constituent of skin and connective tissue. The deficiency of vitamin C causes is known as disease "Scurvy".
