The hydrogenation of the series of methylene-interrupted cis,cis-octadecadienoic acids by pure cultures of six rumen bacteria.
The hydrogenation of all the methylene-interrupted cis,cis-octadecadienoic acids was examined using pure cultures of six rumen bacteria able to hydrogenate linoleic acid to stearic acid or its immediate precursor, trans-11-octadecenoic acid, after first conjugating the linoleic acid to cis,trans-9,11-octadecadienoic acid. Only the delta 14-cis,17-cis-isomer was not hydrogenated by at least one ...
متن کاملThe Metabolism of 14C-Labeled cis and trans Isomers of Octadecenoic and Octadecadienoic Acids
The physical properties of common unsaturated fatty acids are altered when they are converted to their geometric isomers. For example, isomerization of the naturally occurring cis acid, oleic acid, to its trans form, elaidic acid, raises its melting point by 30”, changing it from a liquid to a solid at body temperature. Theoretically, such isomeric pairs might be expect.ed to differ in their me...

متن کاملFatty Acids: Polyunsaturated with Other than Methylene-interrupted Double Bonds
Two types of fatty acids are considered here – those with conjugated double bond systems, and those in which the double bonds are separated by two or more methylene groups. Related fatty acids from plant systems may have acetylenic bonds or oxygenated groups, and these will be considered elsewhere. Similarly, the eicosanoids and hydroperoxides, which can also have conjugated double bond systems...
