A long-standing mystery in gas phase ion chemistry is: why are smaller fragments preferentially lost at low energies and larger fragments at higher energies in competing 伪-cleavages? This is addressed here by studies of dissociations of ethanol, 2-propanol, 2-butanol, 2-methylpropane and 2-...
second, small perturbations of an enzyme that cause large changes in reaction rates. Further, for larger structures such as proteins every thermodynamic measurement depends on the length scale of the structure. One reason is that the larger molecule can control up to thousands of waters resulting i...
