| ascorbic acid | <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) |
| ascorbic acid deficiency | A condition due to a dietary deficiency of ascorbic acid (vitamin c), characterised by malaise, lethargy, and weakness. As the disease progresses, joints, muscles, and subcutaneous tissues may become the sites of haemorrhage. Ascorbic acid deficiency frequently develops into scurvy in young children fed unsupplemented cow's milk exclusively during their first year. It develops also commonly in chronic alcoholism.

| atractosylidic acid | The steroid aglycon and toxic principle of atractylic acid. Synonym: atractosylidic acid, atractylin. (05 Mar 2000) |
| atractylic acid | A highly poisonous steroid glycoside from Atractylis gummifera L. (Compositae), having a strychnine-like action that produces convulsions of a hypoglycaemic nature; the aglycon, atractyliginin, is combined with glucose and isovaleric acid, and is the toxic principle. Atractylic acid interferes with oxidative reactions, the citric acid cycle, and nerve conduction. (05 Mar 2000) |
