| Abstract: | (1) The effect of ketoanalogues of branched-chain amino acids on albumin synthesis was examined in two biological systems using the 14C]carbonate technique. (2)alpha-Ketocaproic acid, the ketoanalogue of leucine, was able to reverse the reduced synthesis rate observed when isolated livers, from well-nourished animals were perfused with blood from rats deprived of dietary protein for 48 h. (3) A mixture of ketoanalogues of the three branched-chain amino acids, leucine, isoleucine and valine, was able to increase albumin synthesis per unit dry liver weight to above normal levels when administered intragastrically to rats 16 h after partial hepatectomy. |
