Pressure Dependence of N-15 Chemical Shifts in Model Peptides Ac-Gly-Gly-X-Ala-NH2
(MDPI AGBASEL, 2012)
High pressure NMR spectroscopy has developed into an important tool for studying conformational equilibria of proteins in solution. We have studied the amide proton and nitrogen chemical shifts of the 20 canonical amino ...
Poly(amide-triazole)s obtained by regioselective, microwave-assisted click polymerization of bio-based monomers
(Elsevier, 2015-03)
The Cu(I)-catalyzed, microwave-assisted click polymerization of bio-based -azide--alkyne monomers afforded, with high regioselectivity, stereoregular poly(amide-triazole)s. The monomers were prepared starting from ...
Alternative amidation approaches
(Universidad de los AndesQuímicaFacultad de CienciasDepartamento de Química, 2021)
Amide bonds play a crucial role in life not only for their function as the backbones of natural peptides and proteins, but also for their presence in a great number of pharmacological compounds, alkaloids, synthetic polymeric ...
Co-adsorbing effect of bile acids containing bulky amide groups at 3β-position on the photovoltaic performance in dye-sensitized solar cells
(2019)
Co-adsorbing molecules attain certain control in the surrounding of the dyes leading to enhanced efficiencies
mainly by affecting the recombination of the photogenerated electrons and aggregation of dyes. Bile acids ...
On the roles of Mg in the activation of G proteins
(Taylor & Francis, 2010-12)
In this review, we highlight the evolution of our knowledge about the way Mg2+ participates in the activation of heterotrimeric G proteins, beginning with its requirement in hormonal stimulation of fat cell adenylyl cyclase ...
Mapping the catalytic pocket of phospholipases A2 and C using a novel set of phosphatidylcholines
(Portland Press, 2000-03)
A set of radioiodinatable phosphatidylcholines (PCs) derivatized with the Bolton-Hunter reagent (BHPCs) was synthesized to probe the substrate recognition and activity of phospholipases. A common feature of this series is ...
Desenvolvimento e estudo das propriedades em meio aquoso de derivados termorresponsivos da carboximetilcelulose
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM QUÍMICA, 2018-01-25)
The present work studies the synthesis and characterization of two copolymers with
thermoresponsive properties, consisting of amino terminated poly (ethylene oxide / propylene
oxide) grafts in a carboxymethylcellulose ...
