Cetoleic acid oxidation

The two most common naturally occurring c/s docosenoic acids are erucic acid (c/s 22 1 n-9) found in the seed oil of the Brassica family and ceto-leic acid (c/s 22 1 n-11) found mainly in marine oils (Ackman et ai, 1971a). The cetoleic acid in fish oils is derived by oxidation of the corresponding alcohol present in small Crustacea which form part of the food chain for marine life (Nenenzel, 1970 Pascal and Ackman, 1976). To date, no longterm studies have been reported in which these two docosenoic fatty acids were fed in purified form. When a comparison was made between a HEAR... 

That peroxisomal p-oxidation probably played an important role in the metabolism of erucic and cetoleic acids was recognized quite early by the investigators who were concerned about the adverse nutritional effects of these long chain monoenoic fatty acids. 

Evidence for the incomplete P-oxidation of erucic and cetoleic acids, a process commonly referred to as chain shortening, has been presented by... 

In this example, we notice that glycolic acid coming from the cetol group of fructose does not transform further. Polyols derivating from sugars, such as sorbitol and mannitol, are oxidized as predicted. Therefore, for these two polyols, which are isomers, the reaction is...
