propionic acid

 [pro″pe-on´ik]
a fatty acid found in chyme and sweat, and one of the products of bacterial fermentation of wood pulp waste; its salts (calcium propionate and sodium propionate) are antifungal agents and inhibitors of mold on foods.

pro·pi·on·ic ac·id

(prō'pē-on'ik as'id), Avoid the misspelling/mispronunciation proprionic.
Methylacetic acid; ethylformic acid; found in sweat; elevated in cases of ketotic hyperglycinemia and in cases of biotin deficiency.
Synonym(s): propanoic acid

propionic acid

/pro·pi·on·ic ac·id/ (pro″pe-on´ik) a three-carbon saturated fatty acid produced as a fermentation product by several species of bacteria; its salts, calcium and sodium propionate, are used as preservatives for food and pharmaceuticals.

propionic acid

[prō′pē·on′ik]
an aliphatic carboxylic acid that is a chemical component of sweat. It can be formed by fermentation of sugars by several species of bacteria. Also called propanoic acid.

pro·pi·on·ic ac·id

(prō'pē-on'ik as'id)
Methylacetic acid; ethylformic acid; found in sweat.

propionic acid

CH3CH2COOH, found in chyme and sweat, and one of the products of bacterial fermentation of wood pulp waste; also an important gluconeogenic volatile fatty acid synthesized by the ruminal microflora. Its salts (calcium and sodium propionate) are used as mold inhibitors in stock feeds and pharmaceuticals, and in topical antifungal preparations.
