Methyl butyrate, also known under the systematic name methyl butanoate, is the methyl ester of butyric acid. Like most esters, it has a fruity odor, in this case resembling apples or pineapples. [2] At room temperature, it is a colorless liquid with low solubility in water, upon which it floats to form an oily layer.

The mevalonate pathway (MVA pathway or HMG-CoA reductase pathway) and the MEP pathway are metabolic pathways for the biosynthesis of isoprenoid precursors: IPP and DMAPP. Whereas plants use both MVA and MEP pathway, most organisms only use one of the pathways for the biosynthesis of isoprenoid precursors.
The red arrow is the succinate fermentation pathway; the blue arrow is the ethanol/acetyl-CoA fermentation pathway, also known as ABE fermentation. Butyryl-CoA is reduced from crotonyl-CoA catalyzing by butyryl-CoA dehydrogenase, where two NADH molecules donate four electrons, with two of them reducing ferredoxin ([2Fe-2S] cluster) and the ...
In enzymology, 3-hydroxybutyrate dehydrogenase (EC 1.1.1.30) is an enzyme that catalyzes the chemical reaction: ()-3-hydroxybutanoate + NAD + acetoacetate + NADH + HThus, the two substrates of this enzyme are ()-3-hydroxybutanoate and NAD +, whereas its three products are acetoacetate, NADH, and H +.
The ABE fermentation pathway generally proceeds in two phases. In the initial acidogenesis phase, the cells grow exponentially and accumulate acetate and butyrate. The low pH along with other factors then trigger a metabolic shift to the solventogenesis phase, in which acetate and butyrate are used to produce the solvents. [4]
Butyrate fermentation is a process that produces butyric acid via anaerobic bacteria. This process occurs commonly in clostridia which can be isolated from many anaerobic environments such as mud, fermented foods, and intestinal tracts or feces. [1]
