(byo͞o′tə-nō′ĭk)

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.

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

Exceptions were methyl geranate, octyl butanoate, and bornylene, in BGM004 genotype, with concentrations about 105%, 110%, and 71% higher, respectively, in DVB/ CAR/PDMS fiber compared to CAR/PDMS.
Indeed, BGM004 presented higher concentration of all major volatile compounds, except for methyl butanoate, whose concentration was statistically similar in both genotypes.
This study showed that the S-HS optimized extraction technique was effective to recovery high concentrations of characteristics major volatile compounds in the passion fruit, such as ethyl butanoate and ethyl hexanoate, which can be advantageous due to the simplicity of the method.[beta]-Pinene, p-cymene, limonene, (Z)-[beta]-ocimene, (E)[beta]-ocimene, [gamma]-terpinene, [alpha]-terpinolene and (E) -4,8-dimethyl-1, 3,7--nonatriene terpenes were identified with the same similarity of recovery in both techniques.
In this case, according to PCA, seven are the compounds that differ in the treatments: 3-methyl-1-butanol, 3methylbutyl propanoate, 3,7-dimethyl-2,6-octadien-1-ol, 3-methylbutyl butanoate, 3-methylbutyl-3-methylbutanoate, 3-phenyl-2-propenal, and dodecanoic acid.
The principal compounds in this analysis are 3-methyl-1-butanol, 3-methylbutyl acetate, 3-methylbutyl butanoate, dodecanoic acid, and phenylmethyl butanoate.
In addition, we found greater transcript levels in liver for all enzymes of butanoate metabolism (such as butyryl Coenzyme A synthetase 1, enoyl Coenzyme A hydratase, hydroxyacyl-Coenzyme A dehydrogenase, and aldehyde dehydrogenase 1) as well as all five alcohol dehydrogenase (ADH) isoforms for metabolizing ethanol and retinol.
Among these esters, ethyl butanoate, ethyl octanoate, and ethyl decanoate were the esters found in greatest concentration.
The investigators found ethyl butanoate, ethyl hexanoate, linalool, 2-heptanone, ionone, 2-heptanol, hexanal, cis-3-hexenol, trans-2-hexenol and furaneol to be the major aroma compounds in Black Diamond.
