Diffusion kinetics in phospholipid vesicles

Abstract

When a chemical reaction takes place in a heterogeneous environment, one can foresee circumstances in which diffusion of one of the participants will have pronounced effects on the observed kinetics of the reaction. This paper presents equations which describe the time dependence of the reactants for the specific case where a chemical reaction takes place on the surface of phospholipid vesicles. The model is implemented on experimental results which consist of the kinetics of the chlorophyll radical which was produced by photoexcitation of chlorophyll, which was dissolved in the phospholipid vesicles and which, as a result of the excitation, transferred its electron to an acceptor which was located outside the vesicle. © 1976.
