Intestinal dipeptide hydrolase activities in undernourished children.
Kumar, V., Ghai, 0. P., and Chase, H. P. (1971). Archives of Disease in Childhood, 46, 801. Intestinal dipeptide hydrolase activities in undernourished children. Intestinal dipeptide hydrolase enzymes cleave dipeptides into amino acids. In 8 undernourished children with diarrhoea, mean intestinal mucosal glyclyl-proline hydrolase activity was reduced 40%, valyl-proline hydrolase activity 38%, a...
متن کاملIntestinal Absorption of Sucrose in Man: the Site of Hydrolysis and Absorption.
Sucrose, unlike the other common disaccharides, maltose and lactose, has been reported to be absorbed poorly from jejunum in man. Using a single-lumen tube technique and giving a carbohydrate-protein-fat meal with a single disaccharide as the source of carbohydrate, Dahlqvist and Borgstr6m (1) reported efficient absorption of lactose and maltose from human jejunum but minimal absorption of sucr...
متن کاملIntestinal Dipeptide Transport in Normal a N D Cystinuric Subjects
1. The absorption of lysine and two lysine-containing dipeptides was studied in normal and cystinuric subjects by jejunal perfusion. Absorption of each dipeptide was compared with that of its constituent amino acids. 2. In normal subjects lysine was better absorbed from the dipeptide glycyl-L-lysine than from the equivalent amino acid mixture. In cystinuric patients lysine was absorbed very poo...
متن کاملIntestinal absorption of protein hydrolysis products: a review.
Many experimental techniques have allowed researchers to probe the fate of hydrolysis products from proteins in the small intestine. An overview of amino acid and peptide absorption from the small intestine is presented with attention given to historical perspectives that have led to current concepts. Speculation about nutritional significance of these processes is offered. Species differences ...
متن کاملRibonucleic acid hydrolysis by intestinal explants of neonatal piglets.
BACKGROUND Healthy human adults are able to hydrolyze dietary nucleic acids and nucleotides in the gastrointestinal tract, thus facilitating absorption of the resulting nucleosides. However, little is directly known of the ability of infants to hydrolyze nucleic acids early in life. METHODS Purified RNA (50, 100, 250, and 500 mg/L) in a suitable medium was exposed to jejunal explants of weani...
