2.3.1.65 choloyl-CoA + glycine Homo sapiens conjugation of bile acids with glycine or taurine favors their excretion into bile and uptake from portal blood into the liver, it promotes absorption of fat and fat-soluble vitamins in the acidic environment of the small intestine by lowering the pKa of the bile acids and hence maintaining its solubility CoA + glycocholate
