| antiberiberi vitamin | A member of the water-soluble B vitamin group, necessary for energy production and carbohydrate metabolism. Deficiency is known as beriberi. (27 Sep 1997) |
| antihemorrhagic vitamin | <biochemistry> A fat soluble vitamin that plays an important role in blood clotting. (27 Sep 1997) |
| antineuritic vitamin | A member of the water-soluble B vitamin group, necessary for energy production and carbohydrate metabolism. Deficiency is known as beriberi. (27 Sep 1997) |
| antiscorbutic vitamin | <biochemistry> A requisite in the diet of man and guinea pigs. May act as a reducing agent in enzymic reactions, particularly those catalysed by hydroxylases. Synonym: Vitamin C. (18 Nov 1997) |
| antisterility vitamin | <biochemistry> Functions as an antioxidant, binds oxygen free radicals that can cause tissue damage, may also play a protective role in the coronary arteries from the damaging effects of cholesterol. (27 Sep 1997) |
| b-complex vitamin | <biochemistry> A group of vitamins that includes: B1(thiamin), B2 riboflavin), B3 (niacin), B6(pyridoxine), B12 (cobalamin) and folate. (24 Mar 1998) |
| vitamin | <biochemistry> An essential low molecular weight organic compound required in trace amounts for normal growth and metabolic processes. They usually serve as components of coenzyme systems. For humans Vitamin A, the B series, C, D1 and D2, E and K are required. Deficiencies of one or more vitamins in the nutrient supply result in deficiency diseases. (11 Nov 1997) |
| vitamin A | <biochemistry> Deficiency of this vitamin interferes with the production of rhodopsin in the eye resulting in night blindness and xerophthalmia. (27 Sep 1997) |
