Stereochemically distinct roles for sterol in (original) (raw)

This research explores the distinct roles of various sterols in the growth of oxygen-deprived Saccharomyces cerevisiae, specifically highlighting two stereochemically different functions. One role is crucial and requires the presence of 24-methylsterol, while the other, potentially regulatory in nature, does not depend on this methyl group. Experimental findings indicate that cholesterol and ergosterol can enhance cell growth synergistically, demonstrating the importance of sterol structure in influencing their efficacy.
