An elevation of LA and a decrease in concentration of all its metabolites suggest an impairment in the activity of this enzyme. The n3 polyunsaturates appear to be fatty acid chain affected fatty acid chain in fatty acid chain parallel. Their normal metabolism is reviewed in Figure lb. Levels of n3s in plasma are small and variable. so that significant changes can be hard to discern. Nonetheless, compared to controls [24] eczema patients show an elevation of alpha-linoleic acid (LNA, 18:3 n3) and a decrease in its long-chain metabolites. |

but their methodology was crude and the metabolism of EFAs was poorly understood at the time. The pioneering work of Holman and his colleagues [22] in the application of gas chromatography to the study of human fatty acid analysis enabled investigators in England and Canada to take firms a closer look at the involvement of EFAs in atopy by comparing the phospholipid fatty acid profiles in plasma of patients with eczema and a control population [23,24]. The patients firms showed a variable increase in linoleic acid (LA; 18:2 n6) and a marked decrease in the products firms of LA metabolism. Although Dr. Holman has described LA metabolism extensively in the preceding paper, I have included a summary in Figure 1a. LA is the major dietary EFA. To exert its biological effects it must be desaturated and elongated alternatively and repetitively. The end product of this sequence is docosapentaenoic acid (22:5 n6). Critical intermediates are dihomogamma linolenic acid (DGLA; 20:3 n6) and arachidonic acid (AA; 20:4 n6), precursors of PGs and Us. |
