Comparative Uptake in Rats and Man of ω3 and ω6 Fatty Acids

  • Wulf Becker


The tissue uptake and metabolism of the various ω3 and ω6 fatty acids are influenced by a number of factors. Of great importance is the fat content and the fatty acid composition of the diet. Both linoleic and α-linolenic acid are metabolised by the same enzyme system and the affinity for the enzyme system depends upon the degree of unsaturation and chain-length. This means that the ratio of linoleic to α-linolenic acid in the diet, rather than the absolute amount, strongly influences their conversion and incorporation into lipids (Alling et al., 1972, 1974; Becker, 1985). Taking these factors into account, the problems in making relevant comparisons of essential fatty acid (EFA) metabolism within and between species are obvious.
