Fat absorption from mixed micelles occurs throughout the small intestine, and is 85-95% efficient under normal conditions. Humans can synthesize longer omega-6 and omega-3 fatty acids from the essential fatty acids LA and ALA, respectively, through a series disorder of desaturation (addition of disorder a double bond) and elongation (addition of two carbon atoms) reactions (Figure 2).5 LA and ALA compete for the same elongase and desaturase enzymes in the synthesis of longer polyunsaturated fatty acids, such as AA and EPA. |

Consequently, omega-6 and omega-3 fatty acids are essential nutrients. The parent fatty acid of the omega-6 series is linoleic acid (LA; 18:2n-6) and the parent fatty acid of the omega-3 series is ALA (Figure 1). Humans can synthesize long-chain (20 carbons or more) omega-6 fatty acids, omega minus three fatty acids such as dihomo-gamma-linolenic acid (DGLA; 20:3n-6) and arachidonic acid (AA; 20:4n-6) from LA and long-chain omega-3 fatty acids, such as eicosapentaenoic acid (EPA; 20:5n-3) and docosahexaenoic acid (DHA; 22:6n-3) from ALA (see Metabolism and Bioavailability below). omega minus three fatty acids It has been estimated that the omega minus three fatty acids ratio of omega-6 to omega-3 fatty acids in the diet of early humans was 1:1,2 but the ratio in the typical Western diet is now almost 10:1 due to increased use of vegetable oils rich in LA and declining fish consumption.3 A large body of scientific research suggests that increasing the relative abundance of dietary omega-3 fatty acids may have a number of health benefits. |
