Carbonyl scavengers such as aminoguanidine or other hydrazine drugs can react with the carbonyl groups of aldose and ketose sugars and thus inactivate them before they can react with proteins.
Knowing that the labelling reaction does not work on nonreducing oligosaccharides or on oligosaccharides containing a ketose at the reducing end, underestimation would be expected since detailed GOS analyses [10,11] have revealed the presence of both nonreducing GOS and GOS that terminate in a fructose.
A ketose is a sugar with a carbonyl (keto) group on the 2-carbon.
