Absorption of L-methionine from the human small intestine.
Absorption of L-methionine was measured in all parts of the human small intestine using transintestinal intubation and perfusion. In four normal subjects, adsorption was higher in the proximal than in the distal intestine. In two patients with nontropical sprue in relapse, there was a proximal zone of low absorption with higher absorption distally. In all parts of the small intestine, absorptio...
متن کاملProduction of equol from daidzein by gram-positive rod-shaped bacterium isolated from rat intestine.
Isoflavones (mainly daidzein and genistin) belong to the flavonoid group of compounds and are classified as phytoestrogens. In the intestine, daidzin is converted to daidzein by beta-glucosidase, and then daidzein is converted to O-desmethylangolensin (O-DMA) or equol via dihydrodaidzein by enzymes of intestinal bacteria. We isolated, for the first time, an anaerobic gram-positive rod-shaped st...
متن کاملFolate transport in isolated brush border membrane vesicles from rat intestine.
The transport of folates by the intact intestine consists of a saturable component with a luminal pH optimum of 6.0 and a nonsaturable component which predominates at high folate concentrations and/or high luminal pH. We sought to determine whether these properties reflect the behavior of the brush border membrane, free of intracellular enzyme activities, organelles, and intercellular junctions...
متن کاملGlucose transport in isolated brush border membrane from rat small intestine.
Uptake of labeled Dand L-glucose has been shown to occur with highly purified brush border membranes from the epithelial cells of rat small intestine using a Millipore filtration technique. An intact glucose carrier system in the isolated membranes was demonstrated as evidenced by the following. (a) D-Glucose was taken up and released faster than L-glucose. (b) Sodium ions increased initial rat...
متن کاملA model of the isolated perfused rat small intestine.
Intestinal edema remains a serious clinical problem, and novel approaches to study its pathophysiology are needed. It was our aim to develop a long-term stable isolated perfused rat small bowel preparation permitting analysis of vascular, luminal, interstitial, and lymphatic compartments and to demonstrate the utility of this model by studying the effects of the proinflammatory mediator platele...
