General description

7-dehydrocholesterol is a metabolite produced in cholesterol synthesis. It is an unsaturated sterol predominantly found in the epidermis.

Application

7-dehydrocholesterol has been used:
  • in gas chromatography/mass spectrometry (GC/MS)-based sterol profiling to quantify 7-dehydrocholesterol in oligodendrocyte progenitor cells (OPCs)
  • as an internal standard for the analysis of sterols and oxysterols using ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS)
  • as an internal standard for lipid measurements by liquid chromatography (LC)-MS

Biochem/physiol Actions

7-dehydrocholesterol acts as a precursor of vitamin D3 under the conditions of high temperature and ultraviolet (UV) light.

7-Dehydrocholesterol, an immediate metabolic predecessor of cholesterol, can accumulate in tissues due to some metabolic abnormalities, causing an array of symptoms known as Smith-Lemli-Opitz syndrome. Enrichment of cellular membranes with 7-dehydrocholesterol interferes with normal cell-signaling processes, which involve interaction between

We demonstrate that polymerizable planar membranes permit reconstitution of protein ion channels formed by the bacterial toxins Staphylococcus aureus alpha-hemolysin (alphaHL) and Bacillus anthracis protective antigen 63. The alphaHL channel remained functional even after membrane polymerization. Surface pressure measurements suggest
