Description

Hexadecanoic Acid-13C16 (Algal Source) is a uniformly carbon-13 labeled isotopologue of palmitic acid, a key saturated fatty acid, derived from a sustainable algal source. This stable isotope-labeled compound is essential for advanced analytical research, providing a critical internal standard for precise quantification and metabolic pathway tracing. It is primarily required by researchers and manufacturers in the pharmaceutical, nutritional science, and biochemistry sectors for applications in mass spectrometry, NMR spectroscopy, and metabolic studies.

Application

• Internal Standard for Mass Spectrometry (MS): Used for the accurate quantification of palmitic acid and related metabolites in complex biological matrices like plasma, tissues, and cell cultures.
• Metabolic Flux Analysis (MFA): Serves as a tracer to study lipid metabolism, fatty acid oxidation, and biosynthesis pathways in vivo and in vitro.
• Nuclear Magnetic Resonance (NMR) Spectroscopy: Provides a non-radioactive, stable isotope label for structural and dynamic studies of lipids and their interactions.
• Pharmaceutical Research & Development: Employed in drug metabolism and pharmacokinetics (DMPK) studies to track the fate of lipid-based drug formulations.
• Nutritional Science Research: Used to investigate dietary fat absorption, distribution, and metabolism in nutritional studies.
• Biochemical Reagent: Acts as a labeled precursor for the synthesis of more complex labeled lipids, such as phospholipids or triglycerides.
• Quality Control in Analytical Laboratories: Ensures method accuracy and validation in food, supplement, and clinical diagnostic testing.
