Beta-Oxidation of Polyunsaturated Fatty Acids

View the 3-D version of this pathway.

It should be noted, that all polyunsaturated fatty acids with a divinyl-methyl configuration are oxidized using the following pathway. Arachadonic Acid is used only as a typical example for illustration purposes.

cis-5,8,11,14-Eicosatetraenoyl-CoA
Arachidonyl-CoA (20:4cD5,8,11,14)
3,6,9,12-Octadecatetraenoyl-CoA
3,6,9,12-Octadecatetraenoyl-CoA (18:4cD3,6,9,12)
2,6,9,12-Octadecatetraenoyl-CoA
2,6,9,12-Octadecatetraenoyl-CoA (18:4D2,6,9,12)
4,7,10-Hexadecatrienoyl-CoA
4,7,10-Hexadecatrienoyl-CoA (16:3cD4,7,10)
