2JC,H index: a nondestructive NMR method for differentiation of aldohexopyranosyl residues.
A new 2J(C,H) index method is described for identification of aldohexopyranose. This method is based on a fact that 2J(C,H) values reflect the stereochemistry for glycol connectivity. Based on the observed 2J(C,H) values for galactose, glucose, and mannose, 2J(C,H) profiles for other aldohexopyranoses are proposed. A combination of 2J(C,H) values was found to be useful for identification of aldohexopyranosyl residues in glycans. [structure: see text]
