Alkaline Phosphatase - an overview | ScienceDirect Topics
Alkaline phosphatase (ALP) is a hydrolase that removes the phosphate group from various proteins and nucleotides. ALP is a leading biomarker of hepatobiliary injury in common preclinical species. Serum ALP levels increase when the patency of the bile duct is reduced, so ALP is widely used in nonclinical and human clinical settings as a marker of cholestatic liver injury.
