these results are discussed in terms of a mechanism involving a solvent-separated glucosyl cation-carboxylate ion-pair , which has greater affinity for alcoholic glucosyl acceptors , and an intimate ion-pair , which has greater affinity for water as a glucosyl acceptor and which could collapse reversibly and rapidly into a preponderance of an unreactive covalent glucosyl-enzyme .
