Metabolite Identification
Common Name7-a,27-dihydroxycholesterol
Description7-a,27-Dihydroxycholesterol, also known as cholest-5-ene-3b,7a,26-triol, belongs to the class of organic compounds known as trihydroxy bile acids, alcohols and derivatives. These are prenol lipids structurally characterized by a bile acid or alcohol which bears three hydroxyl groups. Thus, 7-a,27-dihydroxycholesterol is considered to be a bile acid lipid molecule. 7-a,27-Dihydroxycholesterol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
