| phosphatidylethanolamine | <biochemistry> A major structural phospholipid in mammalian systems. Tends to be more abundant than phosphatidylcholine in the internal membranes of the cell and is an abundant component of prokaryotic membranes. Ethanolamine is attached to phosphatidic acid by a phosphodiester linkage. Synthesis from diacyl glycerol and CDP-ethanolamine. The condensation product of a phosphatidic acid and ethanolamine; found in biomembranes. See: cephalin. (05 Mar 2000) |

| phosphatidylethanolamine cytidylyltransferase | <enzyme> A key enzyme in the biosynthesis of cephaline. It catalyses the reaction of phosphoethanolamine and CTP to form CDP-ethanolamine and pyrophosphate. (05 Mar 2000) |
| phosphatidylethanolamine N-acyltransferase | <enzyme> Transfers acyl groups from sn-1 position of membrane phospholipids to the amino group of ethanolamine phospholipids Registry number: EC 2.3.1- Synonym: penatfase, n-acylphosphatidylethanolamine synthase, nape synthase (26 Jun 1999) |
| phosphatidylethanolamine-ceramide phosphoethanolamine transferase | <enzyme> Cdpethanolamine is not a donor; involved in sphingomyelin synthesis Registry number: EC 2.7.8.- Synonym: pe-cer-pet transferase (26 Jun 1999) |
| phosphatidylethanolamine-dolichol acyltransferase | <enzyme> Forms dolichyl oleate from dioleoyl phosphatidylethanolamine Registry number: EC 2.3.1.- Synonym: pe - dolichol acyltransferase, dolichol acyltransferase (26 Jun 1999) |
| phosphatidylethanolamines | <biochemistry> Derivatives of phosphatidic acids in which the phosphoric acid is bound in ester linkage to an ethanolamine moiety. Complete hydrolysis yields 1 mole of glycerol, phosphoric acid and ethanolamine and 2 moles of fatty acids. (12 Dec 1998) |
| N-acetylsphingosine - phosphatidylethanolamine acyltransferase | <enzyme> Catalyses the esterification of n-acetylsphingosine at the carbon-1 position of the ceramide Registry number: EC 2.3.1.- Synonym: nas-pe acyltransferase (26 Jun 1999) |
