This study aims to evaluate the phenolic contents, chemical composition, mineral amount as well antioxidant activity of methanolic extracts from dried black cumin (Nigella sativa L; family: Ranunculaceae) seed powder. We also performed an in vitro gastrointestinal digestion process understand effect on components and their after digestion. Black showed high amounts total flavonoid such dihydrox...

Previously an experimental infection model was developed in which broiler chickens were inoculated with sporulated Eimeria acervulina oocysts at an age of 18 d. The infection resulted in adverse performance results and reduced nutrient digestion. In two new experiments with the infection model effects of diet adjustments on fat digestion were investigated. In the first experiment addition of 0....

The occurrence of both acid and alkaline ribonuclease activities in liver and kidney was reported in 1954 by Roth (1) and by de Lamirande et al. (2). Since then, investigators have used various methods to purify the intracellular ribonuclease activities (3-8). In our studies, comparatively mild procedures were used for the nuclease preparations (5)) with the hope that the nuclease activities as...

An accurate method based on combination of microwave assisted digestionsuppressed ion chromatography is proposed for the determination of fluoride and chloride in nuclear grade enriched boron (B10). The digestion of the boron matrix is carried out in closed vessel microwave assisted digestion using hydrogen peroxide and dilute nitric acid. By using the microwave assisted approach, the digestion...

The amino acid residues in the carboxyl-terminal region of fructose diphosphate aldolase isolated from fresh rabbit liver are -(Gly,Phe,Leu,Ala,Thr2,Ser2)-Tyr. This differs from the carboxyl-terminal structure in aldolase isolated from tissue which had been frozen and thawed. Amino acid analyses, ultracentrifugation, and digestion with carboxypeptidase suggest that the difference is the result ...

Although it has become clear that brush-border hydrolysis, and consequent utilization of the monosaccharide transport system, is the predominant method of absorption of the luminal products of carbohydrate digestion in man, it now appears certain that two major mechanisms are involved in the absorption of the luminal products of protein digestion: ( I ) transport of liberated free amino acids b...

1. The effect of the addition of acid on the amount of ionized protein has been compared with the effect on the rate of digestion of gelatin, casein, and hemoglobin by pepsin. 2. A similar comparison has been made of the addition of alkali in the case of trypsin with gelatin, casein, hemoglobin, globin, and edestin. 3. In general, the rate of digestion may be predicted from the amount of ionize...
