Metabolite Identification
Common Name22b-Hydroxycholesterol
Description22b-Hydroxycholesterol, also known as cholest-5-en-3b,22R-diol or 22(R)OH cholesterol, belongs to the class of organic compounds known as dihydroxy bile acids, alcohols and derivatives. Dihydroxy bile acids, alcohols and derivatives are compounds containing or derived from a bile acid or alcohol, and which bears exactly two carboxylic acid groups. Thus, 22b-hydroxycholesterol is considered to be a sterol lipid molecule. 22b-Hydroxycholesterol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
