Aspartate aminotransferase(AST) and Alanine aminotransferase (ALT).
Liver tests check the blood for two main liver enzymes: 1  Aspartate aminotransferase (AST), formerly called SGOT; the AST enzyme is also found in muscles and many other tissues besides the liver. 2  Alanine aminotransferase (ALT), formerly called SGPT; ALT is almost exclusively found in In this lab, you will study an enzyme that is found in the cells of many living tissues. The name of the enzyme is catalase (KAT-uh-LAYSS); it speeds up a reaction which breaks down hydrogen peroxide, a toxic chemical, into 2 harmless substances--water and oxygen. Liver enzymes. Serum alkaline phosphatase test. This test is used to measure the level of alkaline phosphatase (an enzyme) in the blood. Alkaline phosphatase is found in many tissues, with the highest concentrations in the liver, biliary tract, and bone. This test may be performed to assess liver functioning and to detect liver lesions that may cause biliary obstruction, such as tumors or abscesses. 1 Aspartate aminotransferase (AST), formerly called SGOT; the AST enzyme is also found in muscles and many other tissues besides the liver. 2  Alanine aminotransferase (ALT), formerly called SGPT; ALT is almost exclusively found in Background information. Liver and other living tissues contain the enzyme catalase. This enzyme breaks down hydrogen peroxide, which is a harmful by-product of the process of cellular respiration if it builds up in concentration in the cells. It is mostly found in the liver in the human body. An enzyme called catalase breaks down hydrogen peroxide into water and oxygen. In experiment number 3, we are comparing the action of catalase in different tissues by testing this hypothesis: The breakdown of hydrogen peroxide occurs at the same rate in all cells. 1 Alkaline phosphatase is found in many tissues, with the highest concentrations in the liver, biliary tract, and bone. 2  This test may be performed to assess liver functioning and to detect liver lesions that may cause biliary obstruction, such as tumors or abscesses.
