Description générale

Desmosterol is a C27 sterol intermediate in cholesterol synthesis. It may be associated with the pathogenesis of Alzheimer′s disease (AD).

Application

Desmosterol has been used as a standard for the estimation of the concentrations of cholesterol and plant sterols. It has also been used to suppress nigericin-induced sterol regulatory element-binding proteins 2 (SREBP2) maturation.
