Common Name3a,7a,12a-Trihydroxy-5b-cholestan-26-al
Description3A,7a,12a-Trihydroxy-5b-cholestan-26-al 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, 3a,7a,12a-trihydroxy-5b-cholestan-26-al is considered to be a bile acid lipid molecule. 3Alpha,7alpha,12alpha-Trihydroxy-5beta-cholestan-26-al is an intermediate in bile acid biosynthesis. Bile acids are also steroidal amphipathic molecules derived from the catabolism of cholesterol. Bile acids have potent toxic properties (e.G., Membrane disruption) and there are a plethora of mechanisms to limit their accumulation in blood and tissues. They exist as anions at physiological pH and, consequently, require a carrier for transport across the membranes of the enterohepatic tissues. 3A,7a,12a-Trihydroxy-5b-cholestan-26-al is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. 3A,7a,12a-Trihydroxy-5b-cholestan-26-al exists in all living organisms, ranging from bacteria to humans. Within humans, 3a,7a,12a-trihydroxy-5b-cholestan-26-al participates in a number of enzymatic reactions. In particular, 3a,7a,12a-trihydroxy-5b-cholestan-26-al can be biosynthesized from 27-deoxy-5b-cyprinol through its interaction with the enzyme sterol 26-hydroxylase, mitochondrial. In addition, 3a,7a,12a-trihydroxy-5b-cholestan-26-al can be converted into 3alpha,7alpha,12alpha-trihydroxy-5beta-cholestanoic acid through its interaction with the enzyme sterol 26-hydroxylase, mitochondrial. In humans, 3a,7a,12a-trihydroxy-5b-cholestan-26-al is involved in cerebrotendinous xanthomatosis (ctx). The distinction between different bile acids is minute, depends only on presence or absence of hydroxyl groups on positions 3, 7, and 12.
