Procedure

The increase in the conversion rate of PUFAs, which had been observed for the total extracts, was clearly also monitored in the neutral lipids. As regards the feeding of linoleic acid (FIGS. 25 A and B), a 2-fold increase in the conversion of linoleic acid into γ-linolenic acid (18:3 Δ6,9,12) and a 3-fold increase in the 20:2 Δ9,12 content was observed. The feeding of linolenic acid (FIG. 26, C and D) gave similar data (conversion of 18:3 into 18:4 3-fold, of 18:3 into 20:3 3-fold).
