K-GATE | D-Gluconate Acid/D-Glucono-δ-lactone Assay Kit
The D-Gluconic Acid/D-Glucono-δ-lactone test kit is suitable for the specific measurement and analysis of D-gluconic acid/D-gluconolactone in foods and beverages.
Extended cofactors stability. Dissolved cofactors stable for > 1 year at 4oC.
UV-method for the determination of D-Gluconic Acid and
D-Glucono-δ-lactone in foodstuffs, beverages and other
(1) D-Gluconate + ATP → gluconate-6-phosphate + ADP
(2) Gluconate-6-phosphate + NADP+ → ribulose-5-phosphate +
NADPH + CO2 + H+
(3) D-Glucono-δ-lactone + H2O → D-gluconate
