Résumé:

In this short paper, it is demonstrated that autoxidation (free radical induced oxidation) of the chlorophyll phytyl side chain in senescent phytoplanktonic cells and higher plants constitutes a potential source of isophytol (3,7,11,15-tetramethylhexadec-1-en-3-ol) in the environment.To explain the formation of this isoprenoid alcohol, mechanisms involving the formation of the precursor 3-peroxy-3,7,11,15-tetramethylhexadec-1-ene are proposed.
