Learn More

Palmitic acid-d31 is a deuterium-labeled palmitic acid, a long-chain saturated fatty acid commonly found in both animals and plants. It can induce glucose-regulated protein 78 (GRP78) and CCAAT/enhancer binding protein homologous protein (CHOP) in mouse granulosa cells. This compound is valuable as a tracer or an internal standard for quantitative analysis in various spectroscopic methods, and its deuterium labeling offers potential benefits for studying pharmacokinetic and metabolic profiles.

• Used as a tracer
• Used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
• Deuterium labeling for pharmacokinetic and metabolic studies
