Glucono-S-lactone

V-D-Gluconylglycine, a pseudopeptide derivative of D-glucono-S-lactone and glycine, was prepared according to ref. 7. The equilibrium constants of its copper coordination, determined according to ref. 1 (Table 1), were used to calculate the concentration distribution curves in Fig. 1, which show the compositions and protonation states of the different species in solutions of different pH. 

Glucono-S-lactone (4.25) has found its application in baking powders, raw fermented sausages, and dairy products where the slow release of acid is required.
