AST (GOT)

Aspartate aminotransferase (AST), also known as glutamate oxaloacetate transaminase (GOT), is an enzyme found in various tissues, including the liver, heart, and muscles. It plays a crucial role in amino acid metabolism by catalyzing the transfer of an amino group from aspartate to alpha-ketoglutarate, forming oxaloacetate and glutamate. Clinically, AST is a significant marker for liver health, as elevated levels often indicate liver damage or inflammation, such as from hepatitis, cirrhosis, or liver cancer. It is also elevated in conditions affecting other organs, such as myocardial infarction or muscle injury. In the context of athletic performance and biohacking, AST levels can reflect muscle damage from intense exercise, providing insight into recovery needs and potential overtraining. However, interpreting AST levels requires caution, as they can be influenced by factors such as recent physical activity, medications, and other health conditions. Researchers have found that fasting and time of day do not significantly impact AST levels, but it is essential to consider these factors when comparing results over time.
