PtdIns-（1-花生四烯酰基，2-花生四烯酰基-d8）（钠盐）

作为稳定同位素稀释MS定量PtdIns-（1-花生四烯酰基，2-花生四烯酰基）的内标。该样品瓶中样品重量的准确度低于样品瓶上所示量的5％至2％。磷脂酰肌醇（PtdIns）占总膜磷脂的一小部分，但它们在细胞信号的产生和传递中起着至关重要的作用。PtdIns-（1-花生四烯酰基，2-花生四烯醇-d8）（钠盐）是天然PtdIns的合成类似物，在sn-2位置含有氘化的C20：4脂肪酸。该合成标准化合物的肌醇和二酰基甘油（DAG）立体化学与天然化合物相同。

ed 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. The phosphatidylinositols (PtdIns) represent a small percentage of total membrane phospholipids, but 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 containing deuterated C20:4 fatty acids at the sn-2 position. This synthetic standard compound features the same inositol and diacyl glycerol (DAG) stereochemistry as that of the natural compound.
