"Vitamin C is an important nutrient in human diets, and necessary to maintain proper tissue and bone. Ascorbic acid and its sodium, potassium, and calcium salts, used as food preservative, are water soluble. Ascorbates, fat-soluble esters of ascorbic acid, are also used as food antioxidant. Ascorbic acid can be easily destroyed under the exposure to oxygen, metals, light and heat." (ChemicalLand21, 2013)
"Vitamin C is an essential nutrient for humans. Ascorbate (an ion of ascorbic acid) is required for a variety of essential metabolic reactions in all animals and plants. It is made internally by almost all organisms. Lack in this vitamin causes the disease scurvy humans. It is also widely used as a food additive." (News Medical, 2014)
