Estimation and comparison of effective compounds (mineral contents, amino acids compositions, fatty acids distributions, protein, fat and total fiber contents) in two algae species Sirophysalis trinodis and Polycladia myrica collected from Qeshm Island were done. The samples washed up with tap water and then were dried in an oven at 40 ◦C for 3 days. The dried algae samples were pulverized and ...

This study describes the effects of different stocking densities on texture/colour characteristics, protein content /amino acid and lipid content/fatty acid composition of rainbow trout fillet. Stocking density was selected 5 (Group A), 15 (Group B), 25 (Group C) kg fish m−3. Tukey’s Multiple Comparison Test showed insignificant differences between measured size/weight measurement and condition f...

Heavy metal contamination of soil, water and air has caused serious environmental hazard in the biosphere due to rapid industrialization and urbanization. A variety of metal binding ligands such as organic acids and amino acids involve in the heavy metal remediation mechanisms by plants. This paper analyses the possible role of amino acid histidine and organic acids, namely, citric, oxalic and ...

The paper deals with the results of an investigation of the release of selected amino acids (histidine, tryptophan, tyrosine) from model suspensions prepared by co-precipitation with zinc chloride. It has been proven that the influence of the Zn(II)/amino acid molar ratio on dissolution profiles of the tested amino acids and dissolution half-life (t1/2) of histidine or tryptophan is significant...

Small viral potassium (K+) channels represent with less than 100 amino acids (aa) per monomer the pore module of every K+ channel. The combination small size and robust function makes them ideal model systems to investigate basic structure/function correlations in channel pores. In prototype KcvPBCV-1 second TM helix ends C-terminus which last aa L94 plays an important role gating. A salt bridg...

Broiler chicks were fed on chemically-defined crystalline amino acid diets containing graded levels of L-threonine (Thr) during the period 10-20 d post-hatching. Doses of Thr represented 5,10,15,40, 55, 70 and 95 % of its ideal level for maximal weight gain and feed efficiency. Other amino acids were maintained at minimized excess levels that were 15 % (of ideal) above the various doses of Thr....

The objective of this paper was to determine the opportunities of improving milk productivity and altering the milk composition through nutritional interventions. The increase in the nutraceutical value of milk is expected through dietary modifications of the animal. Feeding high concentrate diets combined with dietary fat can be used to modify the FA profile of milk, without negative effect on...
