"alanine transaminase"的定义和意义

What is "alanine transaminase"?

Alanine transaminase (ALT) is an enzyme, which is a type of protein that helps speed up chemical reactions in the body. ALT is mainly found in the liver and is crucial in the breaking down proteins into energy. Blood tests measure ALT levels to evaluate liver health. High levels of ALT can be a sign of liver damage or inflammation, which might be because of conditions like hepatitis or fatty liver disease. Monitoring ALT levels helps doctors diagnose liver problems and evaluate treatment progress.
