Oxysterol biosynthetic enzymes

Oxysterols, herein defined as derivatives of cholesterol with a hydroxyl group on the side chain, play several roles in lipid metabolism. Members of this class regulate the expression of genes that participate in both sterol and fat metabolism, serve as substrates for the synthesis of bile acids, and are intermediates in the transfer of sterols from the periphery to the liver. Three abundant naturally occurring oxysterols are...
