Palmitic acid-d（Cat No.:I043808）is a deuterated form of palmitic acid, a saturated fatty acid commonly found in both plant and animal fats. The “d” refers to the incorporation of deuterium, a stable isotope of hydrogen, replacing the hydrogen atoms in the molecule. This modification is used in research to trace metabolic pathways, study lipid metabolism, and investigate the behavior of fatty acids in biological systems. Palmitic acid-d is especially useful in isotope labeling experiments, enabling precise tracking of fatty acid absorption, transport, and utilization within cells and tissues.
