Medium-chain fatty acids defined

Figures 1 and 2 show the capacity of insect homogenates from various stages of development to incorporate medium chain fatty acids (10 0 and 12 0) (fig. lA) as well as unsaturated 18C (18 1 and 18 2) (fig. 2A). In all cases a crossing-zone between the radioactivity patterns of free fatty acids and triacylglycerols is defined in clear coincidence with the larval-pupal apolysis stage. This metabolic difference between larval and pharate adult homogenates could not be explained through differences in the acyl-CoA synthetase activity of the insect furthermore,the enzyme activity increases notably from the larval to the adult stage of development in a manner similar for each fatty acids (figs. IB and 2B).

The TG in nanosized emulsions may be presented structurally in long or medium chains respectively, named LCT and MCT. The mean diameter of particles in LCT emulsions is greater than that in MCT emulsions [29], LCT contains fatty acid chains with 14, 16,18, 20, and 22 carbon atoms and sometimes with double bonds. The number of double bonds present defines the fatty acids in LCT as saturated, mono-unsaturad, or polyunsaturated. If the first double bond is on carbon number 3,6, or 9 from the methyl end of the carbon chain, then the fatty acid is n-3, n-6, or n-9, respectively. Purified soybean or safflower oil contains LCT with a high proportion...
