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.

Butyric acid was first observed in an impure form in 1814 by the French chemist Michel Eugène Chevreul.By 1818, he had purified it sufficiently to characterize it. However, Chevreul did not publish his early research on butyric acid; instead, he deposited his findings in manuscript form with the secretary of the Academy of Sciences in Paris,
β-Hydroxy β-methylbutyric acid [note 1] (HMB), otherwise known as its conjugate base, β-hydroxy β-methylbutyrate, is a naturally produced substance in humans that is used as a dietary supplement and as an ingredient in certain medical foods that are intended to promote wound healing and provide nutritional support for people with muscle wasting due to cancer or HIV/AIDS.
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 ...
The synthesis of even-chained fatty acid synthesis is done by assembling acetyl-CoA precursors, however, propionyl-CoA instead of acetyl-CoA is used as the primer for the biosynthesis of long-chain fatty acids with an odd number of carbon atoms. [19] Regulation. In B. subtilis, this pathway is regulated by a two-component system: DesK and
