Desmosterol is a molecule similar to cholesterol. Desmosterol is the immediate precursor of cholesterol in the Bloch pathway of cholesterol biosynthesis.[1] 24-dehydrocholesterol reductase catalyses the reduction of desmosterol to cholesterol.[2] It is accumulated in desmosterolosis.

In 2014, it was named the Molecule of the Year 2012 by the International Society for Molecular and Cell Biology and Biotechnology Protocols and Researches (ISMCBBPR).[3]
