Definition of nicotinic acid in English: nicotinic acidnounnɪkəˈtɪnɪk mass nounBiochemistry A vitamin of the B complex which is widely distributed in foods such as milk, wheat germ, and meat, and can be synthesized in the body from tryptophan. Its deficiency causes pellagra. 〔生化〕烟酸，尼克酸 Alternative name: 3-pyridinecarboxylic acid; chemical formula: (C₅H₄N)COOH Also called niacin Example sentencesExamples - Because of its ability to cause large reductions in circulating levels of cholesterol, nicotinic acid is used to treat Type II, III, IV and V hyperlipoproteinemias.
- Thus, the enzymes nicotinic acid mononucleotide adenylyltransferase and NAD synthetase are essential for growth of E. coli (coded for by the genes nadD and nadE, respectively).
- If indicated, nicotinic acid and fibric acid derivatives are the most efficacious in lowering triglyceride levels.
- Blood levels of pantothenic acid were significantly higher in CD patients, and there were no statistically significant differences in levels of vitamins B12 and C, nicotinic acid, and biotin.
- Yet this protocol led to the discovery of a low molecular weight molecule that was determined to consist of nicotinic acid, glycine, glutamate, and a sulfur-containing amino acid.
