Experimental short- bowel syndrome: free amino acid versus intact protein in nutritional support. Nutr Res 1994;14:1831-9.Iglesias AC, Portari PE, Zucoloto S, Vannucchi H. Experimental short-bowel-syndrome: free amino acids versus intact protein in nutritional support. Nutr Res 1994, 14: 1831...
Metrics Abstract The emergence of robust methods to expand the genetic code allows incorporation of non-canonical amino acids into the polypeptide chain of proteins, thus making it possible to introduce unnatural chemical functionalities in enzymes. In this Perspective, we show how this powerful methodo...
Domestic cats and dogs are carnivores that have evolved differentially in the nutrition and metabolism of amino acids. This article highlights both proteinogenic and nonproteinogenic amino acids. Dogs inadequately synthesize citrulline (the precursor of arginine) from glutamine, glutamate, and proline in...
Protein quality of fourteen different homemade weaning food mixtures, already evaluated by biological procedures, was also estimated on the basis of amino acid composition. Amino acids were determined by ion鈥恊xchange chromatography with the exception of tryptophan, which was estimated from published ...
Amino acid homeostasis is critical for many cellular processes. It is well established that amino acids are compartmentalized using pH gradients generated between organelles and the cytoplasm; however, the dynamics of this partitioning has not been explo
(S,S)-FeBIPas a catalyst, the reaction provides convenient access tod-configured α-amino acids with proteinogenic side chains, such as Boc-d-leucine (26). For sterically hindered substrates such as 2-cyclohexylacetic acid and 3,3-dimethylbutanoic acid, the desired products27and28were obtained...
The 20 protein-coding amino acids are found in proteomes with different relative abundances. The most abundant amino acid, leucine, is nearly an order of magnitude more prevalent than the least abundant amino acid, cysteine. Amino acid metabolic costs differ similarly, constraining their incorporation...
2.2 Protein quality impact during obesity 2.2.1 Whey protein Beside the quantity of protein consumed, the quality of protein - i.e., its digestibility and its composition in essential amino acids - might have differential effects on metabolism or body phenotype in obesity. With casein, whey prot...
Comparative Analysis of DnaC Protein from Other Bacteria Amino acid sequence alignment of nine dnaChomologs from diverse eubacterial species was performed (Fig. 2). This alignment reveals that amino acids in the N-terminal region are not highly conserved, raising the possibility that formation of ...
Efforts to sequence single protein molecules in nanopores1,2,3,4,5have been hampered by the lack of techniques with sufficient sensitivity to discern the subtle molecular differences among all twenty amino acids. Here we report ionic current detection of all twenty proteinogenic amino acids in an...
