Hydrolysis of galactolipids, phospholipids, sulfolipids and
triglycerides is the first step in ruminal lipid metabolism
resulting in saturated, monounsaturated and polyunsaturated
fatty acids. It has been reported recently that the mechanism
of conjugated linoleic acid (C18:2 cis-9, trans-11, CLA)
production is associated with a prototropic displacement
and the synthesis of its isomer C18:2 trans-10, cis-12, involves
oxidated flavin adenine dinucleotide (FAD). First, linoleic
acid (C18:2 cis-9, cis-12, LiA) is converted to CLA by the
action of cis-9, trans-11 octadecanoate reductase, then CLA
converts to trans-vaccenic acid (C18:1 trans-11, TVA) with
the final product being stearic acid. LiA is the precursor of
both CLA and TVA and FAD is used as a cofactor in these
processes. One of the conclusions of this review is that as
the knowledge of the ruminal biohydrogenation process
increases, opportunities for its application become available.
The nutritional strategies to increase the concentration of
bioactive fatty acids in both milk and meat are the more
relevant.
