phosphatidyln.

1941 J. Folch in Jrnl. Biol. Chem. 139 973 In a recent paper it was shown that cephalin prepared in the usual manner..did not contain..all of its nitrogen in the form of ethanolamine, but that from 40 to 70 per cent was in the form of a β-hydroxyamino acid... The cephalin fraction containing the amino acid has now been isolated, and the amino acid crystallized as..l(+)-serine. We shall call this phosphatide ‘phosphatidyl serine’.

1961 E. S. West & W. R. Todd Textbk. Biochem. (ed. 3) vi. 154 Two different types of phosphoinositides have been described which are differentiated by the inositol derivatives yielded upon hydrolysis. One type found in heart, liver, soybean, and wheat germ yields inositol monophosphate, fatty acids, and α-glycerol phosphate;..it..is phosphatidyl inositol.

1971 M. F. Mallette et al. Introd. Biochem. ix. 324 Phosphatidylserine..is another phospholipid isolated from plant and animal sources.

1975 Phytochemistry 14 2639 This enzyme is also capable of transphosphatidylase activity using primary alcohols as acceptors for the phosphatidyl group.

1985 Sci. Amer. Nov. 54/3 One [substance] is an acidic lipid in the cell membrane called phosphatidylinositol bisphosphate, which decreases in abundance when a cell is stimulated by certain hormones.
