blood enzyme activity level blood aspartate aminotransferase activity level clinical_measurement_ontology aspartate aminotransferase, cytoplasmic measurement EFO:0008031 The amount of enzymatic activity of glutamic-oxaloacetic transaminase enzyme, commonly known as aspartate transaminase or aspartate aminotransferase (AST), in a specified sample of blood. AST catalyzes the reversible transfer of an amine group from l-glutamic acid to oxaloacetic acid, forming alpha-ketoglutaric acid and l-aspartic acid. Blood AST level is used as an enzymatic marker for liver disease or damage. blood aspartate transaminase activity level mshimoyama blood glutamic-oxaloacetic transaminase activity level EFO:0004736 blood GOT activity level CMO:0000580 blood AST activity level VT:0000203 aspartate aminotransferase measurement 2011-11-02T04:17:35Z
