General description

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.

Application

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

Biochem/physiol Actions

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

In this study the sterol and oxysterol profile of newborn brain from the Dhcr7(Δ3-5/T93M) mouse model of Smith-Lemli-Opitz syndrome (SLOS) has been investigated. This is a viable mouse model which is compound heterozygous containing one null allele and one T93M

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

The electronic cigarettes (e-cigarettes, e-cigs) have become the most sought-after alternative to the traditional cigarettes, partly due to the widespread perception of safety. However, the high temperature reached by e-cig solutions can generate toxic compounds, some of which are listed
