Common NameChenodeoxycholoyl-CoA
DescriptionChenodeoxycholoyl-CoA is bile acid Coenzyme A ester. In humans, bile acids conjugated with glycine and taurine are the major solutes in bile, and unconjugated bile acids are almost nondetectable in normal bile. Conjugated bile acids are less toxic and are more efficient promoters of intestinal absorption of dietary lipid than unconjugated bile acids. The synthesis of bile acid and amino acid conjugates in human liver is the result of two independent enzymatic reactions with a bile acid coenzyme A thioester intermediate formation of bile acid-CoA esters, considered the rate-limiting step in bile acid amidation and catalyzed by an ATP-dependent microsomal enzyme, bile acid-CoA synthetase (EC 6.2.1.7). In the second reaction, the thioester bond is cleaved, and an amide bond is formed between the bile acid and the amino acids glycine or taurine. The bile acid-CoA:amino acid N-acyltransferase (EC 2.3.1.65) catalyzes this reaction in the cytosol prior to secretion into bile. In human liver the formation of bile acid-CoA thioesters is localized both to the microsomal fraction catalysed by an ATP-dependent synthetase and to the peroxisomal fraction catalysed by the thiolase in the last step of the beta-oxidative cleavage of the 5beta-cholestanoyl side chain. The highest specific amidation activity of both chenodeoxycholoyl-CoA is always found in the most peroxisome-rich subcellular fractions. (PMID: 2722825 , 10817395 , 11673457 , 10884298 ).
