    • Use of excess acetylthioglycosides 1-3 and a longer reaction time did not result in complete substitution of the carbohydrate units (n = 12) in 4-8, presumably because of steric crowding. Separation of the products with a different degree of carbohydrate substitution (n = 9-12) was practically impossible.

    • ITC is a powerful method to determine the functional valency of a multivalent carbohydrate in binding to lectin,[19a] which may differ from the structural valency. It can be determined from the n value that best fits the ITC data. The n value corresponds to the number of binding sites per ConA monomer, which is the inverse of the functional valency of a carbohydrate cluster to the lectin. An n value of 0.36 (see the Supporting Information) indicates that the binding stoichiometry between 9 and ConA monomer is approximately 1:3, which is consistent with that determined by the turbidimetric Job plot; therefore, 9 behaves predominantly as a trivalent ligand to the lectin
