Uses
16:0 Phosphatidylethanol (Peth)/(1,2-dipalmitoyl-sn-glycero-3-phosphoethanol) may be used:as an internal standard in liquid chromatography?mass spectrometry (LC-MS) analysis of PEth in human whole bloodas an internal standard to spike blood samples for in liquid chromatography high-resolution mass spectrometry (LC?HRMS) analysisas a standard in calibration curve generation and validation of ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-ESI-MS/MS)
General Description
Phosphatidylethanol (PEth) is a phospholipid, that is generated in the the presence of ethanol in cell membranes. PEths like PEth 16:0/18:1, PEth 18:1/18:1, and PEth 16:0/16:0 possesses a common phosphoethanol head. Two fatty acid chains of variable length and degree of saturation are bound to this head group.
Biochem/physiol Actions
Phosphatidylethanol can be used as a biomarker in blood for chronic alcohol use.
Check Digit Verification of cas no
The CAS Registry Mumber 92609-90-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,6,0 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 92609-90:
(7*9)+(6*2)+(5*6)+(4*0)+(3*9)+(2*9)+(1*0)=150
150 % 10 = 0
So 92609-90-0 is a valid CAS Registry Number.

Synthesis and Characterization of Some Acid Phospholipids with Alkyl Head Groups
Kertscher, H.-P.,Gawrisch, K.,Brezesinski, G.
, p. 150 - 153 (2007/10/02)
The acid phospholipids with different long alkyl head groups were prepared total synthetically by direct phosphorylation with phosphorus oxychloride as well as partial synthetically by transphosphorylation with phospholipase D.The characterization was provided by 13C-NMR-spectroscopy, elementary analytically as well as by the phase behaviour, that was determined optically and calorimetrically.The conversion temperatures decrease with increasing number of methylene groups with alkyl head groups systematically, but the conversion enthalpies increases with growing head group length.The conversion temperatures of the phospholipids with perdeuterium head groups don't correspond with their labelled analogues.
