Food chemistry.Food Chem.2016 Apr 15;197(Pt A):400-5. doi: 10.1016/j.foodchem.2015.10.008. Epub 2015 Oct 9.
An analytical method has been developed to determine seleno-amino acids in proteins extracted from extra virgin olive oils (EVOOs). Different aqueous/organic solvents were tested to isolate proteins, an acetone:n-hexane combination being the best protein precipitant. In a first dimension chromatogra

Deducing the functional characteristics of the human selenoprotein SELK from the structural properties of its intrinsically disordered C-terminal domain.

Polo A1, Colonna G, Guariniello S, Ciliberto G, Costantini S.
Molecular bioSystems.Mol Biosyst.2016 Mar 23;12(3):758-72. doi: 10.1039/c5mb00679a. Epub 2016 Jan 6.
The intrinsically disordered proteins (IDPs) cannot be described by a single structural representation but, due to their high structural fluctuation, through conformational ensembles. Certainly, molecular dynamics (MD) simulations represent a useful tool to study their different conformations captur

By using N-fluorobenzenesulfonimide as both the oxidant and the amination reagent, we have realized the first example of the intermolecular chalcogenative amination of alkynes, which grants facile, highly regio- and stereoselective access to chalcogenated enamides. The reaction features mild conditi
