Primary Bile Acid Biosynthesis Analysis Service

Online Inquiry


Bile acids formed by synthesis in the liver are termed primary bile acids. In the liver, synthesis of bile acids and bile salts is initiated with the conversion of cholesterol esters to cholesterol. The primary bile acids are conjugated with taurine or the amino acid glycine before secretion via bile into the intestine, where they function as detergents to solubilize dietary fats. Conjugation increases water solubility, preventing passive re-absorption once secreted into the small intestine. As a consequence, the concentration of bile acids in the small intestine can keep high enough to form micelles and solubilize lipids. Therefore, primary bile acid biosynthesis is a critical component of lipid metabolism. The dysfunction of primary bile acid biosynthesis could lead to a variety of human diseases such as Perrault syndrome and cerebrotendinous xanthomatosis. In Creative Proteomics, we provide reliable, rapid and cost-effective fatty acid synthesis related service to speed up your research aims ranging from diseases diagnosis to gaining new insights in disease mechanism or treatment.
