“…Rudy and Page (46), by a careful fractionation of the mother liquor of ordinary cephalin, obtained a product which agreed with the theoretical composition. This product should correspond, however, to the material containing ethanolamine which Darragh and MacArthur (7) and MacArthur, Norbury, and Karr (38) found in their lecithin fractions, and not to typical cephalin, which has always been identified by its insolubility in alcohol.…”

“…MacArthur, Norbury and Karr (1917) observed that the ethanolsoluble fraction of phospholipids contained its nitrogen equally divided between choline and ethanolamine, showing that the separation of lecithin from cephalin on ethanol solubility was entirely unsatisfactory. It was not until 1930, that Rudy and Page isolated from the ethanol-soluble fraction, a substance containing ethanolamine, which gave the correct analytical figures for the structure that had been ascribed to cephalin.…”

Phosphatidylethanolamine and Lysophosphatidylethanolamine belong to a group of phospholipids generally termed cephalins. The phospholipids are universally distributed among living organisms and are thought to be essential components of cell membranes. From the quantities of lipoidal and protein material found in cell membranes (Danielli and Stein, 1956) together with surface tension and related studies (Danielli and Harvey, 1935; Danielli and Davson, 1935), the membranes are considered to consist of a bimolecular leaflet of lipids with a unimolecular layer of protein adsorbed onto the polar surface. The course of investigation of the cephalin fraction has not been reviewed in recent years, and here is discussed the general scope of the work in this field, under the headings of preparation, structure, synthesis and physical properties.
