The Metabolism of Amino Acids
It was shown by Seth and Luck (1) that the intestinal absorption of glycine and alanine by rabbits was followed by pronounced aminoacidemia. Other amino acids when administered in similar amounts provoked smaller increases in the amino nitrogen content of the blood. Glutamic acid and aspartic acid were absorbed with but a slight aminoacidemia. The question then arose as to whether these strikin...
متن کاملFurther observations on ribonucleic acid metabolism in the liver after administration of individual amino acids.
Toxic effects due to the inclusion of large amounts of individual amino acids in the diet have frequently been noted. In the course of studying the influence of diet on ribonucleic acid (RNA) metabolism in the liver, Munro & Mukerji (1958) gave eighteen amino acids individually in I g quantities to rats and observed considerable increases in the uptake of 32P by liver RNA after administration o...
متن کاملRibonucleic acid metabolism in the liver after administration of individual amino acids.
The effects of protein deficiency on the metabolism of ribonucleic acid in the liver have already been described (Munro, Naismith & Wikramanayake, 1953; Clark, Naismith & Munro, 1957). The amount of ribonucleic acid in the liver falls rapidly during the first day of protein depletion and then becomes adjusted at a lower level. During the initial phase of reduction, uptake of 32p and of [14C]gly...
متن کاملThe metabolism of "surplus" amino acids.
For an adult in N balance, apart from small amounts of amino acids required for the synthesis of neurotransmitters, hormones, etc, an amount of amino acids almost equal to that absorbed from the diet can be considered to be "surplus" in that it will be catabolized. The higher diet-induced thermogenesis from protein than from carbohydrate or fat has generally been assumed to be due to increased ...
متن کاملThe Metabolism of Parenterally Administered Amino Acids
Studies previously reported (l-3)) involving the constant intravenous infusion of a number of amino acids, singly and in combination, have permitted the authors to obtain data concerning a number of physiological and biochemical phenomena associated with amino acid metabolism. The present report deals with the effect of amino acid infusion upon the renal excretion of ammonia. In this phase of m...
