The branched-chain fatty acids of butterfat. I. The isolation from butterfat of branched-chain fatty acids with special reference to the C17 acids.
Although branched-chain saturated fatty acids have been found in the lipids of certain bacteria as well as in wool wax, they have not hitherto been reported as existing in natural glycerides, with the solitary exception of i8ovaleric acid found by Chevreul in 1817 (cf. Hilditch, 1947) in the head and jaw oil of the dolphin. Recently, Hansen & Shorland (1950) observed that the methyl ester conce...
متن کاملFatty Acids: Branched-chain
Branched-chain fatty acids are common constituents of the lipids of bacteria and animals, although they are rarely found in the integral lipids of higher plants. Normally, the fatty acyl chain is saturated and the branch is a methyl-group. However, unsaturated branched-chain fatty acids are found in marine animals, and branches other than methyl may be present in microbial lipids. The most comm...
متن کاملThe Oxidation of Branched Chain Fatty Acids
It is noteworthy that while the majority of fatty acids occurring in nature belong to the normal series, those composed of more than twenty-two carbon atoms contain at least one tertiary carbon atom in their molecu1e.l The structure of these acids is entirely unknown. The problem of their structure naturally is identical with that of the location of t,he tertiary carbon atom. in the molecule. T...
متن کامل.\Production of Branched-Chain Fatty Acids from Sterculia Oil1
Methyl sterculate was rearranged by use of 0.5% of rhodium catalyst to isomeric conjugated diene fatty acid methyl esters containing both methyleneand methyl-branched isomers. The rearranged products were hydrogenated directly to saturated, methyl-substituted, branched-chain fatty acid methyl esters with the methyl substituent at one of the positions formerly occupied by the cyclopropenoid ring...
متن کاملPeroxisomal beta-oxidation of branched chain fatty acids in rat liver. Evidence that carnitine palmitoyltransferase I prevents transport of branched chain fatty acids into mitochondria.
Fatty acid beta-oxidation was investigated in highly purified mitochondrial and peroxisomal preparations from rat liver. Under isotonic conditions, pristanic and homophytanic acid beta-oxidation in purified peroxisomes was severalfold greater compared to the oxidation in purified mitochondria. Branched chain fatty acid beta-oxidation in purified mitochondria was very low, and the oxidation was ...
