The role of amino acids in the regulation of protein synthesis in perfused rat liver. II. Effects of amino acid deficiency on peptide chain initiation, polysomal aggregation, and distribution of albumin mRNA. J Biol Chem 1982;257:2939-46....
The role of perfusate amino acid concentrations in regulating rates of protein synthesis was investigated using the perfused rat liver. Livers from fed rats were perfused with a nonrecirculating medium and the incorporation of [3H]leucine into albumin and total protein was determined under conditions...
More recent studies suggest that the enhanced stimulation of skeletal muscle protein synthesis by feeding in the neonate is primarily insulin mediated; however, the stimulation of liver protein synthesis by feeding seems to be largely a function of amino acid concentration....
coli cells can synthe-size all the standard amino acids, but some mutants, called amino acid auxotrophs, are unable to synthesize a specific amino acid and require its addition to the culture medium for optimal growth. Besides their role in protein synthesis, some amino acids are also ...
and physiological stages on amino acid (AA) pools, protein deposition, and related signaling pathways in different types of skeletal muscles. The study used 48 Landrace pigs and 48 pure-bred Bama mini-pigs assigned to each of 2 dietary treatments: lower/GB (Chinese conventional diet)- or highe...
Anticatabolic effect of branched-chain amino acid-enriched solutions in patients with liver cirrhosis. Reduced muscle protein catabolism following amino acid infusion is consistent with the physiological role of branched-chain amino acids in suppressing protein breakdown and stimulating protein synthesis. Lo...

“hybrid ions”; a zwitterion carries an equal number of positively and negatively charged groups). Any free amino acid and likewise anyproteinwill, at some specific pH, exist in the form of a zwitterion. That is, all amino acids and all proteins, when subjected to changes in pH, pass ...
Identify two roles that proteins play in the body. What are the benefits and risks of taking protein and amino acid supplements? How many amino acids are there and what is their role in the body? Why/how does protein phosphorylation have profound effects on protein structure and function?
4. The primary sources for amino acid synthesis include intermediates from: A. Urea cycle and fatty acid synthesis B. Glycolysis, the citric acid cycle, and the pentose phosphate pathway C. Lipolysis and beta-oxidation D. Protein degradation and amino acid salvage ...
