Green and simple extraction of free seleno-amino acids from powdered and lyophilized milk samples with natural deep eutectic solvents
(Elsevier, 2020-10)
Natural deep eutectic solvents (NADES) were introduced for the extraction of free seleno-amino acids from lyophilized and powdered milk samples. Different NADES were evaluated, and lactic acid:glucose (LGH) showed the ...
Preconcentration of seleno-amino acids on a XAD resin and determination in regional olive oils by SPE UPLC-ESI-MS/MS
(Elsevier, 2014-03-18)
This study describes a method for seleno-amino acids determination in Argentinean olive oils. Preliminary total selenium determination in olive oils probed low concentrations (62.8±1.6 to 117.4±3.0 μg/kg) and the necessity ...
Optimisation of microwave-assisted acid hydrolysis for the determination of seleno-amino acids bound to proteins in powdered milk, lyophilized milk and infant formula
(Academic Press Inc Elsevier Science, 2019-06)
Selenium (Se) is an essential element present in milk as seleno-amino acids and seleno-proteins. To perform an accurate seleno-amino acid analysis, a complete hydrolysis of proteins is necessary. Microwave-assisted acid ...
Biotransformation of Selenium by Lactic Acid Bacteria: Formation of Seleno-Nanoparticles and Seleno-Amino Acids
(Frontiers Media S.A., 2020-06)
Selenium (Se) is an essential micronutrient for the majority of living organisms, and it has been identified as selenocysteine in the active site of several selenoproteins such as glutathione peroxidase, thioredoxin ...
The selenium supplementation influences olive tree production and oil stability against oxidation and can alleviate the water deficiency effects
(Frontiers Media SA, 2018-08-15)
Foliar fertilization with selenium (Se) may well be beneficial in increasing the nutritional and qualitative values of food in Se-deficient regions such as the Mediterranean Basin, and may contribute to an increase in ...
Síntese “one pot” de selenocisteína e seus derivados via mesilato da L-serina protegida
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2009-02-20)
In the present work we developed a new methodology for the “one pot” synthesis of L-seleno- and telullorocysteine, L-seleno- and telullorocystine and L-seleno- and telullorolanthionine derivatives. Through a quite versatile ...
Survival of selenium-enriched lactic acid bacteria in a fermented drink under storage and simulated gastro-intestinal digestion
(Elsevier Science, 2019-09)
Selenium (Se), which is present as SeCys in seleno-proteins, is involved in cancer prevention, thyroid functioning, and pathogen inhibition. Se is incorporated in the diet through Se-containing foods. Some lactic acid ...
Identificação e análise in silico da modulação transcricional de genes de selenoproteínas em Aedes spp
(Universidade Federal de Santa MariaBrasilBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica ToxicológicaCentro de Ciências Naturais e Exatas, 2022-08-27)
Selenium (Se) plays a biological role for many organisms that may include reproduction, immune defense, and
disease resistance. A selenoprotein has an amino acid residue containing the element selenium (Se), called
sel ...
Síntese e aplicação de calcogenetos derivados de peptídeos em catálise assimétrica
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2010-07-12)
In the present work, we have developed a flexible, modular synthetic route for the preparation of new chiral chalcogen peptide derivatives containing sulfur,
selenium or oxygen and evaluate their application as catalysts ...
Food prospects of selenium enriched-Lactobacillus acidophilus CRL 636 and Lactobacillus reuteri CRL 1101
(Elsevier Ltd, 2017-08)
Selenium, which is present as SeCys in selenoproteins, is involved in cancer prevention, thyroid functioning, and pathogen inhibition. Lactobacilli can biotransform inorganic Se into seleno-amino acids. Growth, Se accumulation ...
