On the location of the tetrapyrrole macrocycle of chlorophyll a in phospholipid vesicles and in hexadecane.

M Fragata.   

Abstract

The state of chlorophyll a in phosphatidylcholine vesicles was examined. The results indicate that the chlorophylls are present in monomeric form. A kinetic study of chlorophyll reactions with K2S2O8 and piperidine showed that these substances react with the porphyrin rings of pigments located on both vesicle faces, most probably within the polar headgroup region.
