肝脏是体内分解及转化各种氨基酸的重要器官。除亮氨酸、异亮氨酸和缬氨酸主要在肌肉内分解外,几乎所有的必需氨基酸都在肝脏内进行氧化分解。因而在肝功能严重损害时,常可引起血清中氨基酸的增减与各种氨基酸之间比例的变化。近年来文献中已有关于急性肝炎、酒精性肝病、慢性活动性肝炎(简称慢活肝) The liver is an important organ for the decomposition and transformation of various amino acids in the body. In addition to leucine, isoleucine and valine are mainly broken down in the muscle, almost all the essential amino acids are oxidatively decomposed in the liver. Therefore, serious damage to liver function, often can cause changes in serum amino acid changes and the ratio between the various amino acids. In recent years the literature has been on acute hepatitis, alcoholic liver disease, chronic active hepatitis (referred to as slow living liver)
