The amylolytic system of the B. thuringiensis LBIT 418 showed to be able to act on starch, and the kinetic study showed, at first, the release of dextrins with five or more glucose residues as main products; later, part of the dextrins were converted to maltotrioses and low amounts of...
Each alpha-acid yields a corresponding cis-iso-alpha-acid and trans-iso-alpha-acid upon isomerisation. As discussed before, the correct stereoconfiguration of the iso-alpha-acids has only recently been assigned, but these correct structures have not yet been adopted by all authors, as in many ...
True or false? All chiral compounds with the R configuration are dextrorotatory. The structure of an amino acid allows it to act as both an acid and a base but not simultaneously. Is this true or false? Is the following statement true or false: To be meso, a m...
An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and S-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e.,...
The present invention provides peptide analogues of α-MSH and γ-MSH, comprising the amino acid sequence of human α-MSH or γ-MSH, or variants thereof, and having a branched amino acid probe in the N-terminal part of the peptide.Inventors...

and non-reducing cyclic maltooligosaccharides, known ascyclodextrins, are produced (de Oliveira et al., 2015). The steric arrangement of glucose units of thecyclodextrinmolecule results in a hydrophilic (polar) outer surface and a hydrophobic (nonpolar) inner cavity, which allow CDs to retain a ...
of ligand[62]. Thus GR-beta is considered an antagonist of GR-alpha and counteracts the anti-inflammatory activity of GR-alpha. In vitro studies have indicated that TNF-alpha, IL-1beta, IL-17 and IL-23 can up-regulate GR-beta in PBMCs and other cell types[63,64]. There ...
