Cytoplasmic ast

WebThe half-life of AST in the circulation is 17 +/- 5 hours. The ratio of AST to ALT is sometimes useful to diagnose specific liver diseases. AST is distributed both in cytoplasm and mitochrondria of hepatocytes, while ALT is distributed mainly in the cytoplasm. Normal serum levels of AST are derived from the cytoplasmic fraction. WebAST exists as two genetically and immunologically distinct isoenzymes: cytoplasmic AST (cAST or GOT1) and mitochondrial AST (mAST or GOT2) (15). Both isoenzymes …
