Metal chelates of glycine and glycine peptides.
Since the advancement by Smith et al. (l-4) of the theory that metal ions are chelated simultaneously to enzyme protein and substrate in various polypeptidases, the nature of metal binding to peptides and proteins has become an important as well as an interesting problem. The chelate structures proposed by Smith (3), and later somewhat revised (5, 6), indicate that the metal is bound, at least ...
متن کاملAbsorption and malabsorption of glycine and glycine peptides in man.
The 'glycine tolerance test', an oral dose of glycine followed by analysis of peripheral blood samples, was first used for investigating amino acid absorption more than 30 years ago by Heath and Fullerton (1935), who, though they did not investigate any cases of unequivocal malabsorption, concluded that the test gave 'no useful information regarding the rate of absorption from the gastrointesti...
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 کاملThe absorption of glycine and glycine oligopeptides by the rat.
1. Samples of portal venous and femoral arterial plasma and mesenteric lymph were collected from unanaesthetized rats before and during the intra-duodenal infusion of high concentrations (100 mmoljl) of glycine or glycine oligopeptides (up to and including tetraglycine). 2. There was a marked increase in the concentration of free glycine, and a small amount of diglycine was detected in all the ...
متن کاملGlycine and glycine receptor immunoreactivity in brain and spinal cord.
To study the distribution of glycine immunoreactive neurons in the spinal cord and brain, antisera were raised against glycine conjugated to protein carriers. High-titer rabbit glycine antiserum was purified by affinity chromatography. Testing against other amino acids and peptides with immuno dot blots and ELISA assays showed little apparent cross-reaction with glutamate, aspartate, glutamine,...
