Hydroxyethyl starch (CAS 9005-27-0)

Hydroxyethyl starch (HES) is a synthetic, highly branched amylopectin derivative, extensively utilized in various research applications, particularly for its role in modulating fluid dynamics and membrane permeability in experimental models. As a colloid, Hydroxyethyl starch has unique physicochemical properties that enable it to effectively influence osmotic pressure and volume expansion in experimental systems, making it an invaluable tool for studies focused on understanding the intricacies of fluid management and vascular integrity. Its mechanism of action is primarily through the enhancement of oncotic pressure, mimicking the physiological effects of natural colloids in the body′s fluid compartments. This property of Hydroxyethyl starch is for researchers aiming to dissect the fundamental processes governing fluid equilibrium and transport across cellular barriers. Moreover, the ability of Hydroxyethyl starch to modify the rheological properties of fluids it is added to has led to its widespread application in experiments designed to explore hemodynamics and the viscoelastic properties of biological fluids. As such, Hydroxyethyl starch occupies a pivotal role in the arsenal of research methodologies aimed at elucidating fundamental biological and physiological mechanisms.
