[14C]Taurocholate was orally administered to rats together with a definite amount of either casein- or soy protein-based diet and its postprandial movement along the digestive tract was investigated. A difference was observed between both dietary groups in intraluminal transit as well as mucosal accumulation of [14C]taurocholate in the ileum; namely the soy protein intake led to a decrease in t...

Quantitative light absorption data of the neutral free flavosemiquinone are reported. It is shown that the visible range of the spectrum of the radical is drastically dependent on the solvent. The spectra of the neutral blue flavosemiquinone are compared with those of the blue flavoprotein radicals and conclusions are drawn concerning the environment of the protein-bound flavosemiquinone. The s...

Transfer of an aromatic chromophore from the interior of a protein into the water solvent upon denaturation of the protein produces an absorption change throughout the ultraviolet region, 215 to 320 rnp, approximately 6 times the magnitude of that produced by transfer of the same chromophore from 20% ethylene glycol into water. In the 230 rnE.1 wave length region, the transfer of an indole chro...

Hereditary hemochromatosis is most commonly caused by homozygosity for a point mutation (C282Y) in the human hemochromatosis gene (HFE). The mechanism by which HFE regulates iron absorption is not known, but the C282Y mutation results in loss of cell surface expression of the human hemachromatosis protein (HFE) and hyperabsorption of iron by the duodenal enterocyte. Mice homozygous for a deleti...

Physiol. 213(3) : 557565. 1967.-Starvation and protein-deficient diets caused marked ferrokinetic abnormalities and decreased absorption of iron. Observations at intervals after the onset of fast and in rats fed various amounts of p...

OBJECTIVE Quantitative balance studies were performed to compare fat and calcium absorption in healthy, full term infants fed casein hydrolysate-based (CHF) and soy protein-based (SPF) infant formulas with or without palm olein (PO). Previous studies have reported that PO significantly reduced absorption of both fat and calcium in cow's milk-based formulas in which most of the calcium is inhere...

BACKGROUND & AIMS Previous studies have suggested that iron absorption in suckling mammals is refractory to stimuli that normally would decrease absorption in adults. To better understand the regulation of iron absorption during suckling, we have characterized the relationship between hepcidin, ferroportin, and iron absorption at this crucial stage of life. METHODS To determine whether ferrop...

abstract in order to investigate correlation between the rate (amount) of micro and macro elements and protein percentage in pistachio kernels of six cultivar including: akbari, abbasali, kaleh gouchi, ahmadaghaie, ouhadi and khanjari with aspergillus flavus growth and aflatoxin b1 production, the amount of micro and macro elements were measured using atomic absorption, micro-kjeldhal digestion...
