Description

(2S,3R,4E)-3-hydroxy-2-(octadecanoylamino)octadec-4-en-1-yl 2-(trimethylazaniumyl)ethyl phosphate (2S,3R,4E)-3-hydroxy-2-(stearoylamino)octadec-4-en-1-yl 2-(trimethylammonio)ethyl phosphate 2,3-(N-Steroylsphingosyl)-1-phosphocholine 2,3-Sppc 58909-84-5 C18 Sphingomyelin CHEBI:83358 N-(octadecanoyl)-sphing-4-enine-1-phosphocholine N-octadecanoylsphing-4-enine-1-phosphocholine N-octadecanoylsphingosine-1-phosphocholine N-stearoylsphing-4-enine-1-phosphocholine N-stearoylsphingosine-1-phosphocholine SM(d18:1/18:0) sphingomyelin (d18:1/18:0) stearoyl sphingomyelin (C41H83N2O6P) contains an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
