Common Name26-hydroxycholesterol
Description26-Hydroxycholesterol, also known as cholest-5-ene-3b,26-diol, 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, 26-hydroxycholesterol is considered to be a sterol lipid molecule. An oxysterol that is cholesterol substituted at position 26 by a hydroxy group. 26-hydroxycholesterol is found in Homo sapiens. 26-hydroxycholesterol was first documented in 2010 (PMID: 19761868). 26-Hydroxycholesterol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
