a saturated fatty acid found in butter.

bu·tyr·ic ac·id

(byū-tir'ik as'id),
A foul-smelling acid occurring in butter, cod liver oil, sweat, and many other substances. It exists in two forms: normal butyric acid (also written as N-butyric acid), butanoic acid, which occurs in combination with glycerol in cow's butter; and isobutyric acid, 2-methylpropanoic acid, one of the intermediates in valine catabolism, found in combination with glycerol in croton oil and elsewhere.

butyric acid

n.
A colorless organic acid, C4H8O2, occurring in animal milk fats and used in disinfectants, emulsifying agents, and pharmaceuticals. Also called butanoic acid.

butyric acid

Chemistry
An oily carboxylic acid which smells like rancid butter, has an acrid taste and a sweetish aftertaste, like ether. It is present in rancid butter, parmesan cheese and vomit, and is produced in anaerobic fermentation by bacteria in the colon and axilla (resulting in body odour). It is used as a flavourant, perfume additive and cattle-feed supplement.

It is believed to have anticarcinogenic activity, especially the derivative, sodium butyrate.

Superior quality silage contains a lot of lactic acid, little acetic acid and butyric acid [18,25].
As listed in Supplementary Table 2, the acetic acid yield and accumulative [H.sub.2] yield was 900.7mg/L and 51.6mL, respectively, indicating that the butyrate-oxidizing HPA presented good capacity in butyric acid degradation and provided sufficient substances for methane production.
(2013) who found a higher concentration of butyric acid in corn monoculture compared with corn-faba bean.
In conclusion, the corn oil and sucralphate treatments did not lead to differences in the concentration of acetic acid and butyric acid in this study.
For propionic acid, the caecal pool was 20[micro]mol for the blackcurrant groups versus 13 [+ or -] 0.6[micro]mol for the other berries (P < 0.001) and for butyric acid it was 17[micro]mol versus 13 [+ or -] 0.7[micro]mol for the blackcurrant group and the other berries, respectively (P = 0.032).
