Fatty acid desaturases belong to a group of enzymes family that essentially function in double bonds insertion at specified positions of fatty acyl chains. The localization of the human SCD gene isoforms in a 2R-generated paralogon implies two testable predictions. Lipids Res. However, lipids have a wide range of compounds with tremendous differences in structure. Figure 1. Plant J. Structure and regulation of the omega-3 polyunsaturated fatty acid synthase genes from the deep-sea bacterium Photobacterium profundum strain SS9.
Fatty acid desaturase enzymes and their sources have also been reviewed. Recent. Other enzymes associated with the pathway include 3-ketoacyl-CoA. Fatty acid desaturase enzymes have been broadly classified into two evolutionary. the fatty acyl-CoA reductases (FARs) gene family that encodes.
The mechanisms underlying the rapid evolution of CHC content are not well understood.
These gene families include fatty acid synthases, desaturases. Acyl-CoA desaturases are found in fungal and animal cells in which double A schematic overview of the fatty acid desaturation mechanism.
Mansilla and D. Ten varieties of Indian linseed plus one mutant variety were studied for fatty acid s at different developmental stages.

The desaturase enzymes utilized molecular oxygen, iron cofactors and reducing equivalents usually delivered by NADPH in two forms of electron transport systems depending on the cellular localization of the enzymes.
However, in teleosts Cdx2 has been lost, while Cdx1 has duplicated as a result of 3R [ 30 ].
