Desmosterol
A penultimate sterol in the cholesterol synthesis pathway, primarily used by astrocytes and steroidogenic tissue. Serum desmosterol levels are being investigated as a biomarker for brain cholesterol synthesis and Alzheimer's risk.

Videos Mentioning Desmosterol
#134 - James O’Keefe, M.D.: Preventing cardiovascular disease and the risk of too much exercise
Peter Attia MD
A marker of cholesterol synthesis, monitored closely in Dr. Attia's practice.
#23–Tom Dayspring Part IV of V: statins, Zetia, PCSK9 inhibitors, niacin, cholesterol & the brain
Peter Attia MD
A direct precursor to cholesterol in the Bloch pathway, which predominates in the brain. Serum desmosterol levels can serve as a biomarker for brain cholesterol synthesis, and its suppression by statins is a concern for cognitive health in susceptible individuals.
#21 – Tom Dayspring, M.D., FACP, FNLA – Part II of V: Lipid metrics and cholesterol regulation
Peter Attia MD
A precursor molecule in cholesterol synthesis, similar to cholesterol but with a double bond at carbon 24 in the tail. A deficiency in the enzyme that saturates this bond can lead to a severe genetic disorder.
