Applications Zymosterol is an sterol intermediate in the biosynthesis of cholesterol (C432501). Cholesterol is a major component of all biological membranes; ~25% of total brain lipid is Cholesterol. Zymosterol was also found to be located in the plasma membrane of cultured human fibroblasts via labeling studies.

Applications (3β,5α)-4,4-Dimethylcholesta-8,14,24-trien-3-ol is a follicular fluid meiosis-activating sterol (FF-MAS); a factor present in the pre-ovulatory follicle during the time of oocyte maturation. (3β,5α)-4,4-Dimethylcholesta-8,14,24-trien-3-ol has been shown to protect young oocytes from precocious chromatid separation as well as protecting aged oocytes from predivision during maturation.
