Product Overview
Description:
10-PAHSA 13C4 is a stable isotope-labeled internal standard designed for the precise mass spectrometric quantification of native 10-PAHSA. The corresponding unlabeled molecule is an endogenous branched fatty acid ester of hydroxy fatty acids (FAHFA) combining palmitic acid and 10-hydroxy stearic acid; this lipid class is heavily expressed within adipose tissue and belongs to a family known to modulate glucose tolerance, insulin secretion, and localized inflammatory cascades.

Applications:
10-PAHSA 13C4 is used as an isotopically labeled internal standard for quantitative lipidomics analysis of palmitic acid-hydroxy stearic acid (PAHSA) lipids. Stable isotope labeling enables accurate normalization and quantification of endogenous PAHSA levels in biological samples using LC-MS/MS-based workflows. This compound is valuable for studying branched fatty acid ester of hydroxy fatty acid (FAHFA) metabolism, lipid signaling pathways, and metabolic regulation associated with glucose and energy homeostasis.
