Aszpartáttranszamináz
Aszpartáttranszamináz, often abbreviated as AST, is an enzyme found in various tissues throughout the body, including the liver, heart, muscles, kidneys, and brain. Its primary function is to catalyze the transfer of an amino group from aspartate to alpha-ketoglutarate, forming oxaloacetate and glutamate. This reaction is a crucial step in amino acid metabolism and the urea cycle.
In clinical medicine, AST is primarily known as a biomarker for liver damage. When liver cells are
