Because it is essentially half phenylalanine, people who have the genetic disease phenylketonuria (PKU) and cannot metabolize phenylalanine normally need to avoid diet drinks and other products containing aspartame (trade name: NutraSweet).
- Aspartate aminotransferase (AST)
Aspartate aminotransferase (AST): Also known as serum glutamic oxaloacetic transaminase (SGOT), AST is an enzyme that is normally present in liver and heart cells. AST is released into blood when the liver or heart is damaged. The blood AST levels are thus elevated with liver damage (for example, from viral hepatitis) or with an insult […]
