ascorbic acid
Ascorbic Acid: A six carbon compound related to glucose. It is found naturally in citrus fruits and many vegetables. Ascorbic acid is an essential nutrient in human diets, and necessary to maintain connective tissue and bone. Its biologically active form, vitamin C, functions as a reducing agent and coenzyme in several metabolic pathways. Vitamin C is considered an antioxidant.. L-ascorbic acid : The L-enantiomer of ascorbic acid and conjugate acid of L-ascorbate.. L-ascorbate : The L-enantiomer of ascorbate and conjugate base of L-ascorbic acid, arising from selective deprotonation of the 3-hydroxy group. Required for a range of essential metabolic reactions in all animals and plants.. vitamin C : Any member of a group of vitamers that belong to the chemical structural class called butenolides that exhibit biological activity against vitamin C deficiency in animals. The vitamers include L-ascorbic acid and its salt, ionized and oxidized forms. | 2.04 | 1 | 0 | ascorbic acid;

folic acid
folcysteine: used to promote fertility in chickens. vitamin B9 : Any B-vitamin that exhibits biological activity against vitamin B9 deficiency. Vitamin B9 refers to the many forms of folic acid and its derivatives, including tetrahydrofolic acid (the active form), methyltetrahydrofolate (the primary form found in blood), methenyltetrahydrofolate, folinic acid amongst others. They are present in abundance in green leafy vegetables, citrus fruits, and animal products. Lack of vitamin B9 leads to anemia, a condition in which the body cannot produce sufficient number of red blood cells. Symptoms of vitamin B9 deficiency include fatigue, muscle weakness, and pale skin. | 2.04 | 1 | 0 | folic acids;
