Biosynthesis
It is synthesized from lathosterol by the enzyme lathosterol oxidase (lathosterol 5-desaturase). This is the next-to-last step of cholesterol biosynthesis. Defective synthesis results in the human inherited disorder lathosterolosis resembling Smith–Lemli–Opitz syndrome. Mice where this gene has been deleted lose the ability to increase vitamin D3 in the blood following UV exposure of the skin.
