The steric number of a molecule is the number of other atoms bonded to the central atom of the molecule plus the number of lone pairs of electrons attached to it. This is used to determinemolecular geometrybecause electrons in pairs repel each other, whether those pairs are bonding electrons ...
While you can't use VSEPR to calculate bond angles, it helps determine those angles based on steric number. Only hydrogen has a steric number of one, and the H2 molecule has a linear shape. Hybridized Orbitals An electron orbits an atom in a characteristic shape determined by the most likel...
Hsp90 is an essential molecular chaperone responsible for the folding and activation of hundreds of ‘client’ proteins, including the glucocorticoid receptor (GR). Previously, we revealed that Hsp70 and Hsp90 remodel the conformation of GR to regulate l

Prion-like low-complexity domains (PLCDs) have distinctive sequence grammars that determine their driving forces for phase separation. Here we uncover the physicochemical underpinnings of how evolutionarily conserved compositional biases influence the phase behaviour of PLCDs. We interpret our results in ...
aas witnesses to the accident,we were asked to make written declarations of what we had seen 作为事故的证人,我们请求做书面声明什么我们看见了 [translate] aTo design our manufacturing and testing capability,we must determine the maximum size of any flaws that might lead to failure within the 10 ...
Explain how to determine nodes and antinodes. Nodes and Antinodes: In a wave pattern, there are some points that seem to be stationary. These points, typically delineated as points of no displacement, are cited as nodes. There are different points ...
It is exactly opposite to the situation in most aqueous systems for which the solvating agent (the water molecules) is in excess and the number of ions correlates instead with the amount of the dissociating agent. In order to determine the size of these "stericaly stabilized" ions we use ...
Unfortunately, because these are enzymatic reactions, it will be difficult to determine whether the effects are predominantly on the binding enthalpy or the entropy. In an attempt to establish whether the altered affinities of restricted ligands arise primarily from enthalpic or entropic effects, my ...
According to the Valence-Shell Electron-Pair Repulsion Model, widely accepted among chemists since its development in the 1950s, the repulsion between electron pairs shapes the molecule in such a way as to reduce the repelling energy, or maximize the dis
