ALAT
ALAT (ALT) is an enzyme found mainly in the liver, where it helps the body process amino acids.
ALAT (alanine aminotransferase, ALT) is an enzyme found mainly in the liver cells, where it helps the body process amino acids. A small amount passes into the blood all the time, and the level rises when more is released from the liver. Following ALT over time gives context on how the liver is doing.
Alcohol, a diet high in sugar and processed food, and body weight all affect ALT. Some medicines and supplements, a recent infection and very hard training can raise it for a while. Levels also differ somewhat between men and women.
