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 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
Ketogenesis pathway. The three ketone bodies (acetoacetate, acetone, and beta-hydroxy-butyrate) are marked within orange boxes. Ketogenesis is the biochemical process through which organisms produce ketone bodies by breaking down fatty acids and ketogenic amino acids.

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 ...
Derivatives: butyrate (butanoate), sodium butyrate, methyl butyrate, ethyl butyrate, butyl butyrate, pentyl butyrate; Valeric acid (pentanoic acid) – constituent of valerian; has an unpleasant odor and fruity flavor and esters are used as additives Derivatives: valerate (pentanoate), methyl valerate, ethyl valerate, pentyl valerate
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 Wood–Ljungdahl pathway is a set of biochemical reactions used by some bacteria. It is also known as the reductive acetyl-coenzyme A ( acetyl-CoA ) pathway . [ 1 ] This pathway enables these organisms to use hydrogen ( H 2 ) as an electron donor , and carbon dioxide (CO 2 ) as an electron acceptor and as a building block for biosynthesis .
