Description

Sterculic Acid CAS NO 738-87-4 is a unique, naturally occurring cyclopropene fatty acid of significant industrial and research interest. Its core value lies in its potent biological activity as a specific inhibitor of the stearoyl-CoA desaturase (SCD1) enzyme, a key regulator of fatty acid metabolism. This makes it a critical compound for researchers in life sciences and a valuable intermediate for manufacturers in the nutraceutical, pharmaceutical, and agricultural chemical sectors seeking to develop products targeting metabolic pathways.

Application

• Biomedical & Pharmaceutical Research: As a well-characterized inhibitor of the stearoyl-CoA desaturase (SCD1) enzyme, it is essential for studying lipid metabolism, obesity, diabetes, and cancer pathways in preclinical models.
• Nutraceutical & Dietary Supplement Development: Investigated for its potential role in modulating body composition and metabolic health, serving as a key ingredient or reference standard for product formulation and quality control.
• Agricultural & Animal Science: Used in research to explore the manipulation of fatty acid profiles in livestock to improve meat quality and in crop science for developing novel plant traits.
• Biochemical & Enzymology Studies: Employed as a specific tool compound to inhibit SCD1 activity in cell-free systems, cell cultures, and tissue samples to elucidate enzymatic functions.
• Reference Standard & Analytical Chemistry: Serves as a high-purity certified reference material (CRM) for analytical methods like GC-MS and HPLC in quality control labs for identifying and quantifying cyclopropene fatty acids.
• Cosmeceutical Research: Explored for potential applications in topical formulations aimed at modulating skin lipid composition and addressing conditions like acne or dermatitis.
