The interactions of retinol with vesicles of dioleoylphosphatidylcholine of varying radii were studied.The rate constants of dissociation of retinol from bilayers (k(off)) and the equilibrium partition constants (Keq) of retinol into bilayers of different sized vesicles were measured.The rate constants for association of retinol with vesicles were
