A NATO Advanced Study Institute held in Portugal in 1968 on cellular biology directed our attention to the important role that biological membranes played in the fundamental life processes, e.g. the transportation of cellular nutrients into cells and into subcellular par ticles coupled with energy use/or generation. A consi deration of biomembranes and their structure led us to organize a self-supporting course in 1972 under the gen eral sponsorship of the American Oil Chemists' Society on "Fundamentals of Lipid Chemistry." This course con cluded with important papers on lipoproteins,...
