Is the given molecule chiral? Provide the stereocenter(s). Stereocenters:An atom with three or more distinct attachments is referred to as a stereocenter, and when two of these attachments are switched, a new stereoisomer is produced. A carbon atom with four distinct attachments is sp3 (...
The molecule contains a chiral center and exists as d-(left) and l-enantiomers (right). To determine whether one of the enantiomers is more active than the other, we measured the inhibition of basal- and MT-activated ATPase activities using Eg5 concentrations of 0.7 and 0.073 μm, respectiv...
When the lysine is removed, the aggregated fibrils are likely due to the increased hydrophobicity of the molecule, but the fibrils are able to transform into tubes after an annealing cycle; again, the CD spectra revealed right-handed β-sheets for both the aged and annealed cases. However, ...
ChemInform Abstract: THE SYNTHESIS OF A CHIRAL RECEPTOR MOLECULE CONTAINING THREE CARBOHYDRATE RESIDUES WITHIN A 20‐CROWN‐6 CONSTITUTIONcarbohydratesThe rationale behind designing and the approach to synthesising chiral crown ethers incorporating three trigonally-disposed carbohydrate residues is presented as...

6a–c) was found 76 meV more stable than at the A-step (Supplementary Fig. 13). Such an energy difference, albeit small, is likely the reason that all triangles have the same orientation. The chemical interaction between a helicene molecule and the step was evaluated by the electron ...
Some specific considerations regarding the derivatization of proteins and peptides are the following. In proteins and peptides because of the presence of more than two reactive functions per molecule, multiple labeling could result in differently tagged compounds. As an example, trypsin inhibitors (from...
For transport assays, the molecule to be tested (2 mM GAP, 2 mM ATP (already contained for each reconstitution except for the BS3 crosslinking experiment in the presence of only GAP), 200 µM MANT-ATP, 2 mM NADH, 140 µM bromophenol blue, 100 µM magnesium green ...
We classify the research in this field into the following two categories: (1) chiral photoreactions conducted through forming host-guest complexes in different stoichiometries; (2) chiral template-mediated photoreaction by virtue of strong supramolecular interactions, such as hydrogen-bonding, π-...
