Product Overview
Description:
Palmitic acid-d9 is a nona-deuterated stable isotope internal standard engineered for the absolute mass spectrometry-based quantification of native palmitic acid, which represents the primary 16-carbon saturated fatty acid in human physiology, accounting for 10-20% of dietary lipid intake and constituting approximately 25% of total plasma lipids and 65% of circulating saturated fatty acids. At a cellular level, palmitoylation serves as an obligatory mechanism anchoring membrane-bound proteins to the lipid bilayer, dictating intracellular trafficking, driving protein-vesicle interactions, and governing G protein-coupled receptor functions.
Labeling:
Stable isotope-labeled
