is there ast enzyme in muscle
Aminotransferase (AST) is an enzyme thatâs present in various parts of your body. An enzyme is a protein that helps trigger chemical reactions that your body needs to function. AST is found in the highest concentrations in your muscles, heart, red blood cells, and liver. A small amount of AST is typically in your bloodstream. Higher-than-normal amounts of this enzyme in your blood may be a sign of a health problem. Any AST level below 40 units per liter (U/L) in adults isnât uncommon.
