Allgemeine Beschreibung

7-dehydrodesmosterol (7-DHD) is synthesized via the Bloch pathway. 7-DHD serves as a desmosterol synthesis precursor and the enzyme 7-dehydrocholesterol reductase (DHCR7) catalyzes this step.

Anwendung

7-dehydrodesmosterol has been used as an internal oxysterol standard in ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS).

Biochem./physiol. Wirkung

7-dehydrodesmosterol (7-DHD) levels are higher during fetal development and increases with aging. Elevated levels of 7-DHD is associated with Smith-Lemli-Opitz syndrome mouse model. Reduced levels of 7-DHD is observed in shiverer and quaking disorder.

In rat sciatic nerve, the 7-dehydrocholesterol content decreased dramatically during the postnatal period and slowly during adulthood and aging. In contrast, the 7-dehydrodesmosterol content peaked at 14 days and was nearly undetectable after 60 days. The desmosterol content peaked at

Cholesterol and cholesterol-derived oxysterols are critical for embryonic development, synapse formation and function, and myelination, among other biological functions. Indeed, alterations in levels of cholesterol, sterol precursors, and oxysterols result in a variety of developmental disorders, emphasizing the importance of
