7α,27-Dihydroxycholesterol

7α,27-Dihydroxycholesterol is an oxysterol characterized by its oxidized side chains and is produced through the hydroxylation of 27-Hydroxycholesterol (27-OHC); it serves as a metabolite of interest in lipidomic analyses of various pathological conditions, including neurological diseases, Smith-Lemli-Opitz syndrome, obesity metabolic syndrome, and diabetes. Notably, levels of 7α,27-di-OHC decrease following lipopolysaccharide activation, and it also functions as a ligand for Epstein-Barr virus-induced gene 2 (EBI2). Additionally, 7α,27-di-OHC exists as a structural isomer of 7α,25-dihydroxycholesterol (7α25-OHC).
