Sodium metaperiodate, or sodium m-periodate, is a mild oxidant that is routinely used for the conversion of cis-glycol groups in carbohydrates to reactive aldehdye groups (Figure 1).  The reactive aldehyde groups are used in chemical conjugation procedures or detection of carbohydrates.  For proteomic research, sodium m-periodate is used for the oxidation of the carbohydrate moiety of glycoproteins and offers the advantage of modifying the sugar side chains as opposed to critical amino acids.

The resulting aldehydes can interact with primary amines to from Schiff’s bases, which in turn can be stabilized by reduction with sodium cyanoborohydride to form covalent amide bonds. Alternatively, the aldehydes can spontaneously react with hydrazide activated molecules to form relatively stable hydrazone bonds, which again can be stabilized with sodium cyanoborohydride.
