Serial measurements of alkaline phosphatase and 5'-nucleotidase multiple forms in two patients undergoing surgical procedures to release biliary obstruction suggested an inverse relationship between high-M(r) isoforms and serum bile acids concentrations. Furthermore, the study of several groups of patients with cholestatic disorders confirmed this inverse correlation. Mechanisms responsible for these observations are discussed.

D000469	Alkaline Phosphatase	An enzyme that catalyzes the conversion of an orthophosphoric monoester and water to an alcohol and orthophosphate. EC 3.1.3.1.
D015720	5'-Nucleotidase	A glycoprotein enzyme present in various organs and in many cells. The enzyme catalyzes the hydrolysis of a 5'-ribonucleotide to a ribonucleoside and orthophosphate in the presence of water. It is cation-dependent and exists in a membrane-bound and soluble form.
