ascorbic acid, l-ascorbic acid vitamin c, called also cevitamic acid; a substance found in many fruits and vegetables, especially citrus fruits, such as oranges and lemons, and tomatoes. It is synthesized by most animal species, except primates, guinea pigs, fruit bats and some birds and fish, and so is not a dietary requirement in ordinary circumstances except for the species named. ascorbic acid nutritional deficiency occurs in primates and guinea pigs with inadequate dietary intake; affected animals are weak, depressed, anorectic, and have enlarged joints. In farm animals the only example of a possible secondary deficiency is a dermatosis of young calves which occurs at a time at which ascorbic acid levels might be expected to be at their lowest. The syndrome includes heavy dandruff, alopecia and a waxy crust on the skin. Want to thank TFD for its existence?
