Recently I described a method for the separation of neutral amino-acids from neutral peptides of low molecular weight on the anion exchanger 'Dowex-1' with ammonium acetate buffer p H 8.65 (ref. 3). At this p H the monoaminomonocarboxylic acids, which all have pK values for the amino ...
Recent years have witnessed the discovery that amino acids (AA) are not only cell signaling molecules but are also regulators of gene expression and the protein phosphorylation cascade. Additionally, AA are key precursors for syntheses of hormones and low-molecular weight nitrogenous substances with ea...
“reactive” high-molecular-weight intermediates of sediment organic matter remineralization) or abiotic condensation products of, e.g., melanoidin-type reactions. In the former case, the DCAA pool might be expected to be more similar to that of sediment amino acids, while in the latter case ...
30、that of proteins containing amino acids with many hydrophilic groups.If the primary structure of the protein were not folded, protein molecules would be excessively long and thin. A protein having a molecular weight of 13,000 would be 448 a thick. This structure allows excessive interaction ...

Ten physical properties of amino acids were evaluated to determine how each property contributes to mutability across the VLP (Fig.5). Size-based parameters (volume, molecular weight, length, and steric bulk) seem to group by region, where a set of several proximally positioned residues show sim...
8.13.3.2.2 Resolution of β-amino acids CSPs based on (+)-(18-crown-6)-2,3,11,12-tetracarboxylic acid have been widely applied for the resolution of various β-amino acids. CSP 6 was quite successful for the resolution of various β-amino acids including β-2-homo-amino acids and β...
The endosome-to-Golgi or endocytic retrograde trafficking pathway is an important post-Golgi recycling route. Here we show that amino acids (AAs) can stimulate the retrograde trafficking and regulate the cell surface localization of certain Golgi membran
