Other animals unable to synthesize vitamin C include primates, fruit bats, guinea pigs, and some birds. What is vitamin C?. It is one of the most abundant vitamins that is required in large amounts by humans.. Dietary sources :. Vitamin C is found in a wide variety of fruits and vegetables.. Fats and meat are lacking of . The vitamin is easily . oxidized. to form . dehydroascorbic acid (DHAA). , and thus oxidation is readily reversible. Vitamin C is a generic name for all compounds that exhibit the same biologic activity as AA. Consequently, the term includes both AA and DHAA. The structure formula of vitamin C(Ascorbic acid) closely resembles that of carbohydrates..
