Aspartate Aminotransferase (AST) is one of a group of enzymes which catalyzes the interconversion of amino acids and alpha-keto acids. AST is mostly used in the evaluation of liver disease. Both AST and ALT are normally found in most body fluids, but not in urine except in instances of kidney lesions.
