Stearyl arachidate (CAS 22432-79-7)

Stearyl arachidate is an ester derived from stearyl alcohol and arachidic acid, widely studied in lipid research due to its unique structural properties. As a long-chain fatty acid ester, it serves as a model compound for investigating the formation and behavior of lipid bilayers and other biomembrane structures. Researchers are particularly interested in its hydrophobicity and stability, making it suitable for studies on lipid crystallization and polymorphism. This compound is utilized in experiments aiming to understand the solid-liquid phase transitions of lipids, providing insights into the thermotropic behavior of saturated fatty acid esters. It aids in elucidating the interactions between fatty acids and alcohols in complex lipid matrices, revealing the critical parameters that influence lipid organization in biological membranes. Additionally, stearyl arachidate is used to develop lipid-based nanomaterials and coatings due to its capacity to form ordered structures with favorable barrier properties. Its application extends to the exploration of lipid assembly in various colloidal systems, like micelles and vesicles, offering a platform for studying the encapsulation and stabilization of hydrophobic compounds. Overall, stearyl arachidate is instrumental in lipidomics and biophysical research, enhancing the understanding of lipid architecture and dynamics.
