In view of the great importance bestowed on amino acids as antioxidants in oxidation resistance, we attempted two common redox titration methods in this report, including micro-potassium permanganate titration and iodometric titration, to measure the antioxidative capacity of 20 amino acids, which are the construction units of proteins in living organisms. Based on the relative intensities of t...

background: ferroportin (fpn), a regulator of iron homeostasis is a conserved membrane protein that exports iron across the enterocytes, macrophages and hepatocytes into the blood circulation. fpn has also critical influence on survival of microorganisms whose growth is dependent upon iron, thus preparation of fpn is needed to study the role of iron in immunity and pathogenesis of micoorganisms...

the aim of this study was to investigate the effects of in ovo injections of albumin, ami-no acid and dextrose into the amnion on the hatchability, growth performance and slaughter yield of ross 308 broiler chicks. fertile eggs (n=360) were assigned to 6 treatment groups (4 replicates of 15 eggs each) including: non-injected eggs (control), and eggs injected with 0.7 ml distilled water (sham), ...

abstract bee venom is a complex mixture of proteins, peptides and low molecular components: proteins (enzymes) :( phospholipase, a2phospholipase b, hyaluronidase α – glucosidase) - , peptides (melittin, apamine mcd peptide,adolapine ,procamine a and b, protease inhibitors)- low molecular components: biogenic amines:( histamine, dopamine and noradrenalin) - pheromones: complex ethers- sugars :( ...

The rate at which amino acids are removed from the blood by the organs has been previously reported (l-3). The methods used permitted only estimation of total amino acid nitrogen, and no information could be gained as to the fate of the individual amino acids injected. Quantitative paper chromatography (4) seemed to lend itself as a valuable method in studying the pattern of absorption of paren...

Co-fermentation of finger millet with horse gram was carried out to produce inexpensive protein-rich food (dosa-an Indian breakfast food). Natural fermentation of finger millet-horse gram flour blend in different proportions (2:1, 3:1, 4:1 and 5:1) was performed for 24 h. Biochemical analysis showed reasonable drop in pH (6.6-4.2) and starch content (25.52%) with considerable augment in titrata...

In this paper, the ultrasonic absorption of amino acids was measured using a small cylindrical resonator at physiological pH and 25°C and a concentration of 0.1. M. The absorption of mixtures of some amino acids was also measured. In the case of cysteine-histidine, the absorption of mixtures is much larger (more than twice) than the summation of absorption of the individual amino acid. This...

The present study conducted to investigate the effect of energy sources and levels on performance and breast meat amino acids profile in Cobb 500 broiler chicks. A total of 600 1-day-old Cobb 500 broiler chicks with an average weight of 39 ± 0.50 g were randomly divided into five treatments. Each treatment was further divided into four replicates. Chicks were fed a basal diet based on corn and ...
