The emission energy, fluorescence quantum yield and lifetime exhibited a biphasic dependence on solvent polarity. In aprotic solvents, alcohols and in ethanol-water mixtures containing less than 40% water, quantum yields and lifetimes were high (approximately 0.55 and 8.5 ns respectively). In ethanol...
Describe the correlation between electronegativity, polarity, bond length, and bond energy using examples. Give a good definition for the term ionic bond when it comes to structures and bonding in chemistry. Determine the bond energy of the H-Cl bond if the bond energy of the H-H bond is ...
Membrane traffic operates by vesicles that bud from precursor organelles and are transported to their target compartment where they dock and fuse. Targeting requires tethering factors recruited by small GTPases and phosphoinositides whereas fusion is car
When the threonine was replaced by alanine there was an ~3 fold decrease in AZ10606120 sensitivity (p < 0.001). However the conservative substitution to serine, that maintained polarity with a small decrease in size of the side chain, did not change AZ10606120 sensitivity. These results ...
