18-polyunsaturated fatty acid and that the cyclopropanes arise from the addition of one-carbon units donated by S-adenosylmethionine or its equivalent. Since the thermodynamically most stable form of this hypothetical precursor is all-trans, then the cyclopropanes and olefins in 2 would also be trans. equation presentated
