Tests
The determination of the ratio of alanine aminotransferase (ALT) compared to aspartate aminotransferase (AST) present in a sample. The measurement may be expressed as a ratio or percentage.
Indicators
A family of pyridoxal phosphate-dependent enzymes involved in amino acid metabolism and in the urea and tricarboxylic acid cycles. Aspartate aminotransferase specifically and reversibly catalyzes the transfer of an amino group from L-aspartate to alpha-ketoglutarate forming oxaloacetate and L-glutamate.
Tests
The determination of the amount of aspartate aminotransferase isoenzyme C present in a sample.
Tests
The determination of the amount of aspartate aminotransferase isoenzyme M present in a sample.
Tests
A quantitative measurement of aspartate aminotransferase present in a sample.
Tests
The determination of the ratio of aspartate aminotransferase compared to creatine kinase present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
The determination of the ratio of aspartate aminotransferase compared to creatinine present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
A quantitative measurement of the amount of aspartate aminotransferase present in a sample of serum.
Glossary Term
A volatile liquid prepared by fermentation of certain carbohydrates. Alcohol acts as a central nervous system (CNS) depressant, a diuretic, and a disinfectant. Although the exact mechanism of CNS depression is unknown, alcohol may act by inhibiting the opening of calcium channels, mediated by the binding of the inhibitory neurotransmitter gamma-amino butyric acid (GABA) to GABA-A receptors, or through inhibitory actions at N-methyl-D-aspartate (NMDA)-type glutamate receptors. Alcohol inhibits the production of antidiuretic hormone, thereby producing diuresis that may lead to dehydration. This agent kills organisms by denaturing their proteins.
Tests
An AST blood test measures the amount of AST in your blood. This test is commonly used to help diagnose liver damage or disease .
Indicators
A non-essential amino acid. In hepatocytes, L-citrulline is synthesized in the urea cycle by the addition of carbon dioxide and ammonia to ornithine. L-citrulline is converted into L-arginine by the enzymes argininosuccinate synthetase and argininosuccinate lyase in the presence of L-aspartate and ATP. Subsequently, L-arginine is converted to nitric oxide by nitric oxide synthase and L-citrulline is regenerated as a by-product.
