Abstract
26-Hydroxylated derivatives participate in several pathways of cellular metabolism. The 26-hydroxylation in bile acid biosynthesis has been studied extensively. A 26-hydroxylation is involved also in vitamin D3 metabolism. By virtue of being potent inhibitors of enzymes in cholesterol biosynthesis, some 26-hydroxylated sterol derivatives, such as 26-hydroxycholesterol, have been ascribed a role in regulation of sterol biosynthesis.
