Furthermore, recently, as amino acid metabolism abnormalities and protein metabolism in liver failure become clear, the necessity of nutritional treatment considering the amino acid composition of food to correct the imbalance of plasma free amino acids in liver failure has been discussed. (Meiji Watanabe et al., JJPEN 3:10

The decrease in leucine and isoleucine) is due to the increased insulin uptake of branched-chain amino acids in muscle and adipose tissues due to increased liver injury, and increased blood aromatic amino acids (phenylalanine, tyrosine) and tryptophan. Is hyperprotein catabolism in the liver and muscle,
It is thought to be due to a decrease in the ability of the liver to synthesize proteins and a decrease in the ability of the liver to process aromatic amino acids (phenylalanine, tyrosine) and tryptophan. Therefore, a drug intended for liver failure is composed of free amino acids having a significantly increased ratio (Fisher ratio) between branched-chain amino acids (valine, leucine, isoleucine) and aromatic amino acids (phenylalanine, tyrosine).
