Standard periodate cleavage counts are sucrose X=3, glucose Y=5 and fructose Z=5. In the monosaccharides each consecutive eligible C-C bond along the six-carbon chain consumes periodate; sucrose has two eligible bonds in the glucopyranosyl unit and one in the fructofuranosyl unit because anomeric glycosidic positions block further cleavage. Thus (5+5-1)/3=3.
