Photochemical hydrogen-deuterium exchange reaction of tryptophan: the role in nonradiative decay of singlet tryptophan
Description
The mechanism of nonradiative decay of singlet excited tryptophan (Trp) in aqueous solution was investigated by a highly selective photosubstitution of the C-4 hydrogen of Trp with deuterium of solvent D2O. It was concluded that intramolecular proton transfer from the α-ammonia group giving rise to formation of a protonated species plays an important role in the nonradiative decay of singlet Trp at neutral pH. 11 references, 1 figure
