Product Overview
Description:
Palmitic acid-13C labeled at positions C1, C2, C3, and C4 is a multi-carbon stable isotope internal standard designed for the high-precision mass spectrometry-based quantification of native palmitic acid via GC-MS or LC-MS platforms. The unlabeled target analyte is a fundamental 16-carbon saturated fatty acid that represents 10% to 20% of standard human dietary lipid intake, constituting approximately 25% of total circulating human plasma lipids and 65% of the total saturated fatty acid pool; the post-translational acylation of this lipid core to proteins governs critical cellular trafficking, anchoring membrane-bound proteins securely to the lipid bilayer, facilitating protein-vesicle interactions, and regulating the topological signaling of diverse G protein-coupled receptors.
Labeling:
Stable isotope-labeled

Applications:
Palmitic acid-13C (C1, C2, C3, and C4 labeled) serves as a partially stable isotope-labeled saturated fatty acid reference standard for mass spectrometry workflows, providing a distinct non-overlapping heavy-mass signature to trace real-time lipid chain elongation, desaturation, and incorporation kinetics.
