【 摘 要 】

Subcellular fractions from developing seeds of mustard (Sinapis alba), honesty (Lunaria annua) and nasturtium (Tropaeolum majus) synthesize very long chain cis (n−9) monounsaturated fatty acids, e.g. gadoleic (20:1), erucic (22:1) and nervonic (24:1) acid, from oleoyl-CoA and malonyl-CoA by condensation reactions. The particulate 2000 × g and 15 000 × g fractions exhibit considerably higher elongase activities compared to the microsomal or oil body fractions, whereas the soluble (150 000 × g supernatant) fraction is devoid of such activities.
