Amino Acid Composition Determination of the Regulatory Complex "Baipas" by Capillary Electrophoresis Method

Отрасль птицеводства играет ведущую роль в обеспечении населения полноценными продуктами питания. Признавая тот факт, что продуктивность сельскохозяйственной птицы напрямую зависит от уровня кормления, учёным приходится изыскивать резервы кормовой базы для полноценного обеспечения гранулы комбикорма всеми необходимыми питательными элементами. Нами был изучен аминокислотный профиль многокомпонентного регуляторного комплекса «Байпас», который полностью восполняет потребность птицы в аминокислотах. Нашими исследованиями установлено, что ядро аминокислотной составляющей кормовой добавки представляют три аминокислоты: аргинин, глицин и лизин. В целом кормовая добавка содержит 13 аминокислот, что положительно отразится на усвоении питательных элементов комбикорма, а, следовательно, на продуктивности сельскохозяйственной птицы. The poultry-rearing industry plays a leading role in providing the population with balanced food products. Recognizing the fact that the productivity of agricultural poultry directly depends on the level of feeding, scientists have to find reserves of the fodder base to fully provide the compound animal feedstuff pellets with all the necessary nutrients. We have studied the amino acid profile of the multicomponent regulatory complex "Baipas", which fully meets the need for amino acids in poultry. Our researches have found that the nucleus of the amino acid component of the feed additive is represented by three amino acids: arginine, glycine and lysine. In general, the feed additive contains 13 amino acids, which will positively affect the absorption of nutritional elements of compound animal feedstuff, and, therefore, the productivity of poultry.

Cross metathesis-mediated synthesis of hydroxamic acid derivatives

An alternative synthesis of α,ß-unsaturated hydroxamates via cross metathesis between a class-I olefin and N-benzyloxyacrylamide is reported. The reaction proceeds better in the presence of Grubbs’ second generation catalyst within short time and in good yields (57–85%) with a range of substrates. Subsequent hydrogenation of each of the CM products delivers the title compounds in moderate to very good yield (70–89%). An important demonstration of the protocol is the preparation of the unusual amino acid component of the bioactive cyclic peptide Chap-31.

Komposisi Kandungan Asam Amino Pada Teripang Emas (Stichoupus horens) di Perairan Pulau Bintan, Kepulauan Riau

This study aims to analyze the amino acid component contained in the golden sea cucumber so that it can be used as a basis for consideration, management, especially the development of sea cucumbers. Protein in sea cucumbers have complete amino acids, both essential amino acids and non-essential amino acids. The result of the proximate test of golden sea cucumber has high protein content which is 95,14% and fat 0,20% compared to other sea cucumber type while the protein of sea cucumber is very low that is 1.78% and 1.54% ash. The highest content of dried sea cucumber amino acids in golden sea cucumber meat seen in glutamic acid of 6.6049%, 7.1769% glycine, aspartic acid 3.9227% and proline of 3.4189% while the results of wet sea cucumber amino acids have a low amino acid value with glutamic acid 0.2281%, Glycine 0.2308% and Alanin 0.2169%.

Binaphthyl-anchored antibacterial tripeptide derivatives with hydrophobic C-terminal amino acid variations

The facile synthesis of seven new dicationic tripeptide benzyl ester derivatives, with hydrophobic group variations in the C-terminal amino acid component, is described. Moderate to good activity was seen against Gram-positive bacteria in vitro. One cyclohexyl-substituted compound 2c was tested more widely and showed good potency (MIC values ranging from 2–4 μg/mL) against antibiotic-resistant strains of Staphylococcus aureus and Enterococci (VRE, VSE), and against Staphylococcus epidermidis.
