The Effect of the Hydrogen Ion Concentration on the Rate of Hydrolysis of Glycyl Glycine, Glycyl Leucine, Glycyl Alanine, Glycyl Asparagine, Glycyl Aspartic Acid, and Biuret Base by Erepsin
1. The rate of hydrolysis at different pH values of glycyl glycine, glycyl leucine, glycyl alanine, glycyl asparagine, glycyl aspartic acid and biuret base has been determined. 2. The pH-activity curves obtained in this way differ for the different substrates. 3. The curves can be satisfactorily predicted by the assumption that erepsin is a weak acid or base with a dissociation constant of 10(-...
متن کاملSolvent Effect Study on the Stability Energies of Glycine, Alanine and Valine Amino Acides
Glycine, Alanine and Valine are taken as amino acids with an equal polar head and with thedifference in the length of hydrocarbon chains. The structural optimizations show the results of theisolated Glycine, Alanine and Valine in the gases phase, at the Hartree-Fock level by means ofSTO-3G,3-21G, 6-31G and 6-31+G basis sets. The calculations were performed for the ten (1-10)solvents using PCM m...
متن کاملAbsorption of glycine and L-alanine by the human jejunum.
Most, if not all, ingested protein is degraded into amino acids, which are then absorbed. Absorption of amino acids has been studied in intact animals, everted gut sacs, and in other preparations of intestine. These studies have been reviewed recently (1, 2). Comparatively little is known, however, about amino acid absorption in the human. Kuroda and Gimbel (3) showed that when racemic amino ac...
متن کاملElectric susceptibility of unsolvated glycine-based peptides.
The DC electric susceptibilities of unsolvated glycine-based peptides, WGn (W = tryptophan and G = glycine) with n = 1-5, have been measured by deflection of a molecular beam in an electric field. These are the first electric deflection measurements performed on peptides. At 300 K the susceptibilities are in the range of 200-400 A(3). By far the largest contribution to the susceptibilities is f...
متن کاملCore-level electronic structure of solid-phase glycine, glycyl-glycine, diglycyl-glycine, and polyglycine: X-ray photoemission analysis and Hartree-Fock calculations of their zwitterions.
X-ray photoelectron spectroscopy (XPS) has been used to investigate the core-level electronic structures of glycine (G) and its peptides, including glycyl-glycine (GG), diglycyl-glycine (GGG), and polyglycine (poly-G), in their powder forms. Increasing the number of G units in the peptides does not change the locations of the respective C 1s, N 1s, and O 1s features corresponding to different f...
