Absorption 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 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 کاملProlinuria: defect in intestinal absorption of imino acids and glycine.
T.K., a female, was born after full term and spontaneous delivery, weighing 2,260 g. Her parents were healthy and not consanguineous. There was no sibling. The patient was breast fed and appeared to be healthy until 6 months of age, when the parents wondered if she might be mentally retarded. Even beyond one year of age she could neither stand nor sit alone. There was no history of convulsions ...
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 کاملThe number of glycine residues which limits intact absorption of glycine oligopeptides in human jejunum.
Studies were performed to determine whether glycine peptides of four or more glycine residues can be transported by the peptide carrier system, previously shown to transport diglycine and triglycine. When human jejunum was perfused with tetraglycine solutions, the rate of tetraglycine disappearance increased linearly as the concentration was increased over the range of 12.5-50 mM, however, the ...
