Abstract
Among the various theories of aging, the membrane hypothesis of aging is particularly appealing (Sun and Sun, 1979; Grinna, 1977). Cellular membranes function in mediating and regulating active transport of substances across the cell boundary as well as serving as an important permeability barrier. Enzyme activities and receptor functions are also modulated by the lipid composition of membranes. The nature of membranes may change during aging either as a result of oxidative damage (Tappel, 1973) or from a deterioration of homeostatic mechanisms that maintain proper lipid composition (Kates and Kuksis, 1980). In vitro and in vivo manipulation of membrane lipids may thus provide a model of aging.
