Autor: Richard J. Robins, Isabelle Billault, Sébastien Guiet, Michele Lees
Publikováno v: Phytochemistry. 64(1)
We have previously demonstrated that 2H distribution in fatty acids is non-statistical and can be related to isotopic discrimination during chain extension and desaturation. Petroselinic acid (C18:1 Delta(6)), a fatty acid characteristic of the seeds
