Most importantly, recall that a polymer has a degree of polymerization, and a single turnover is not about one polymer participating in any transformation to a product. With disaccharide as substrate, for instance, and a known large molar mass of sucrase and a relatively lower molar mass of sucrose, № could be very large (as large as a value ≥ exp. (regarded as kcat, albeit not exactly so) may not be the same as the number of catalytic cycles per unit time.
