The Effect of Protein Loads on Plasma Amino Acid Levels
... (Felig, 1973). The branched-chain amino acids are deaminated more slowly than other amino acids in the liver, and normally depend on the extrahepatic tissues for their metabolism (Miller, 1962; Ning, Lowenstein & Davidson, 1967; Felig, 1973). This explains the finding that they show the most sustain ...
