The composition of biologically active substances in the aqueous total fraction 95% EtOH extract aerial part Alfredia cernua (L.) Cass. possessing antiamnesic properties was studied using chromatographic and mass-spectrometric methods. amount N-containing compounds found to be 10.63 ± 1.65%. Fifteen amino acids (1.99 0.11%), seven which (0.76 0.012%) were essential included lysine, threonine, v...

lysozyme is one of the bioactive components of eggs with well known antibacterial potential, widely used in food industry, medicine and pharmaceutics. in this study, the possibility of quail’s egg lysozyme concentration and activity (modified via amino acids dietary supplementation) was investigated. in accordance with lysozyme amino acids profile, four amino acids of: asparagine, arginine, gly...

Amino acid content before and after heat treatment was assessed in grain of six selected amaranth varieties and four species: Amaranthus cruentus, A. hypochondriacus, A. caudatus and A. hybridus, cultivated in the Czech Republic. High content of Lys and Arg was detected in both heat treated and untreated grains, as well as satisfactory content of Cys and lower levels of Met, Val, Ile and Leu. T...

Rice contains antioxidants, minerals, carbohydrates, lipids, vitamins that make it a functional food. A dozen times higher content of antioxidants was noted in black-grain and red-grain rice varieties as compared to white-grain ones. In terms protein content, color do not differ significantly. The composition largely determines the nutritional value properties, well texture taste rice. Although...

Studies by Christensen et wl. (1, 2) and by -4llison and associates (3) have demonstrated that the urinary excretion of peptides is greater than the urinary excretion of free amino acids following the infusion of partial hydrolysates of casein or of fibrin. Christensen and coworkers have shown also that infusion of these hydrolysates results in a greater persistence of peptides in the plasma th...

In a recent study of recovery of amino acids added to human plasma, it was found that L-tryptophan was bound by a nondialyzable plasma component (1). In the present work, this solute is identified as serum albumin. This observation is of considerable interest since tryptophan is an essential amino acid, with many pathways of metabolism. An investigation was, therefore, undertaken to determine w...

1. The bacterial reverse mutation test uses amino-acid requiring strains of Salmonella typhimurium and Escherichia coli to detect point mutations, which involve substitution, addition or deletion of one or a few DNA base pairs (1)(2)(3). The principle of this bacterial reverse mutation test is that it detects mutations which revert mutations present in the test strains and restore the functiona...
