in an endeavor to find a novel series of antihyperglycemic agents, new benzimidazole and pyrimidine derivatives were successfully synthesized efficiently in high yield with high purity, starting from amino acids in the presence of phosphorus oxychloride (pocl3). the synthesized compounds were identified by 1h-nmr, 13c-nmr, ft-ir spectroscopic techniques and elemental analysis. all products were...

an experiment was conducted to determine apparent ileal digestibility of crude protein (cp) and amino acids (aa) and digestible cp and aa of fish meal (fm) in 21-d-old broiler chickens using the regression technique. four diets containing 0, 1, 2, and 3% fm in place of cornstarch were formulated with fm as the sole contributor of cp and aas in the sequential diets. eighty 14-d-old broiler chick...

in current study, protein hydrolysates were produced using microbial proteases of alcalase, protamex and flavourzyme from yellowfin tuna viscera. the results indicated that, protein hydrolysate from alcalase, had significantly higher protein content, nitrogen recovery and degree of hydrolysis than the others (p 0.05). the results of amino acids composition revealed that all hydrolysates were al...

Blood amino acid compartmentation between plasma and red blood cells was studied in mice bearing the Lewis lung carcinoma. The animals showed a change in compartmentation with an increase in the concentration of most amino acids in the plasmatic fraction with the exception of glycine, glutamine, aspartate, asparagine, and taurine. This work focuses on the importance of studying the distribution...

The transport of organic N compounds to the shoot in the xylem sap of nodulated soybean plants was investigated in an attempt to better understand the changes in N metabolism under root hypoxia (first 5 days of flooding), with different sources of N in the medium. NO3 is beneficial for tolerance of plants to waterlogging, whereas other N sources such as NH4 + and NH4NO3, are not. Nevertheless, ...

BACKGROUND Nutritional supplementation may be used to treat muscle loss with aging (sarcopenia). However, if physical activity does not increase, the elderly tend to compensate for the increased energy delivered by the supplements with reduced food intake, which results in a calorie substitution rather than supplementation. Thus, an effective supplement should stimulate muscle anabolism more ef...

Two mechanisms have been proposed for the modulation of skeletal muscle glucose metabolism by amino acids. Whereas studies on humans and cultured cells suggested acute insulin desensitization via mammalian target of rapamycin (mTOR) and its downstream target p70 S6 kinase (S6K), investigations using native specimens of rat muscle hinted at impairment of glucose oxidation by competition for mito...

The functional processes and mutual benefits of the wild plant Moringa oleifera its rhizosphere microbiome were studied via metagenomic whole-genome shotgun sequencing (mWGS) in comparison with a bulk soil microbiome. results indicated high gene abundance four KEGG categories, “Cellular Processes”, “Environmental Information Processing”, “Genetic “Metabolism”, Most enriched enzymes rhizobacteri...

The kidneys play a role in the synthesis and interorgan exchange of several amino acids. The quantitative importance of renal amino acid metabolism in the body is not, however, clear. We review here the role of the kidney in the interorgan exchange of amino acids, with emphasis on quantitative aspects. We reviewed relevant literature by using a computerized literature search (PubMed) and checki...
