Abstract
The previously unresolved 3J(CC) coupling between the imidazole C-2 and the C-β carbons of histidine has been observed in [90%-13C-2]histidine as a function of pH; comparison of the results with theoretical finite perturbation theory INDO calculations indicates significant hydrogen bonding from the amino to imidazole units at neutral pH.This publication has 4 references indexed in Scilit:
