| 描述 | PtdIns-(3)-P1(1,2-dipalmitoyl)-d62 (ammonium salt) contains 62 deuterium atoms at the 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 9, 10, 10, 11, 11, 12, 12, 13, 13, 14, 14, 15, 15, 16, 16, and 16 positions. It is intended for use as an internal standard for the quantification of PtdIns-(3)-P1 (1,2-dipalmitoyl) (ammonium salt) by GC- or LC-mass spectrometry. The phosphatidylinositol (PtdIns) phosphates represent a small percentage of total membrane phospholipids. However, they play a critical role in the generation and transmission of cellular signals.1,2PtdIns-(3)-P1(1,2-dipalmitoyl)-d62 is a synthetic analog of natural PtdIns featuring deuterated C16:0 fatty acids at the sn-1 and sn-2 positions. It is intended for use as an internal standard for the quantification of PtdIns-(3)-P1 by GC- or LC-mass spectrometry. This synthetic standard compound contains the same inositol and diacyl glycerol (DAG) stereochemistry as that of the natural compound. |
