PtdIns-(1-arachidonoyl, 2-arachidonoyl-d8), 1-(1-(5Z,8Z,11Z,14Z)-eicosatetraenoyl-2R-(5Z,8Z,11Z,14Z)-eicosatetraenoyl-5,6,8,9,11,12,14,15-d8-phosphatidyl)inositol, monoammonium salt
PtdIns-(1-arachidonoyl, 2-arachidonoyl-d8) is used as an internal standard for the quantification of PtdIns-(1-arachidonoyl, 2-arachidonoyl) by stable isotope dilution MS. The accuracy of the sample weight in this vial is between ,5% over and 2% under the amount shown on the vial. If better precision is required, the deuterated standard should be quantitated against a more precisely weighed unlabeled standard by constructing a standard curve of peak intensity ratios (deuterated versus unlabeled).,The phosphatidylinositols (PtdIns) represent a small percentage of total membrane phospholipids. However, they play a critical role in the generation and transmission of cellular signals. PtdIns-(1-arachidonoyl, 2-arachidonoyl-d8) (sodium salt) is a synthetic analog of natural PtdIns featuring deuterated C20:4 fatty acids at the sn-2 position. This synthetic standard compound contains the same inositol and diacyl glycerol (DAG) stereochemistry as that of the natural compound.
