 [bu-tir´ik]
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.

Although the process of butyric acid degradation can also be divided into three phases, it differed from that of propionic acid degradation.
Our results were similar, while no statistically significant difference was found between PBS (pH 7.4) and butyric acid (pH 5.4) solutions.
The second method is based on the transesterification of triglycerides as FA pentyl esters; the elongation of the alcohol chain produced heavier esters and increased the length of the ester of butyric acid to nine carbon atoms.
Contrary to what was reported by Frank et al (13), the gastric contents of this study showed butyric acid concentrations of 40%.
The objective of the present study was to investigate the adsorption behaviours by use of activated carbon (AC) for the removal of benzoic acid (BA), valeric acid (VA), butyric acid (BUA) and propionic acid (PA) from aqueous solutions by changing their initial concentration.
Examples include polypeptides, cellulose derivatives, polylactic acid resins, polypropylene oxides, and poly(betahydroxy butyric acid).
In order to study effect of various concentrations of Indole butyric acid (IBA), Naphthalene acetic acid (NAA) and mixture of these two hormones (IBA+NAA) on the rooting of semi-hardwood cutting of the Azalea alexander L., an experiment was carried out in a greenhouse around the Salmanshar.
Among the organisms targeted by GTI's qPCR testing are total bacteria, total archaea, sulfate-reducing bacteria, sulfate-reducing archaea, acid-producing bacteria (acetic and butyric acid producers), iron-oxidizing bacteria, denitrifying bacteria, and methanogens.
These ferment some carbohydrates to butyric acid instead of the desired lactic acid [8].
They found that a chemical, 4-phenyl butyric acid, that relieves this stress, prevents die cells from failing, suggesting a potential target for clinical intervention.
