... Problem 3 (2 points) 1. In class, the “isolobal analogy” was presented as a way to predict the stability and bonding of hypothetical organometallic compounds. Roald Hoffman describes it as a “bridge between organic and inorganic chemistry” (Angew. Chem. Int. Ed., 1982, 21, p. 711). Using the isoloba ...

... Schiff base ligands are widely used in coordination chemistry mainly due to their tunable steric and electronic properties and good solubility in common solvents. Complexes with oxygen and nitrogen donor schiff bases are particularly focused because of their sensitivity towards molecular environment ...

Phosphate binding sites identification in protein
... In many PbSs, the phosphate is involved in a network of hydrogen bonds with the backbone atoms of the protein residues. The backbone forms a geometrically and energetically favorable scaffold, which tightly binds the phosphate ion. Glycine residues have a critical role in these binding sites as they ...
