Protochlorophyllide and protochlorophyll in model membranes - An influence of hydrophobic side chain moiety

► We studied protochlorophyll and protochlorophyllide in liposomes ► Protochlorophyllide and protochlorophyll enter the bilayer of galactolipids liposomes ► Protochlorophyll in phospholipid vesicles formed transient aggregates ► The porphyrin macrocycle was found in the lipid headgroup area of liposomes ► The side chain forced protochlorophyll molecule to localize deeply in the bilayer
