Adenosine-5′-diphosphoglucose disodium salt is a nucleotide substrate commonly used as a glucose donor. Adenosine-5′-diphosphoglucose disodium salt is made in the plastids by the enzyme ADPglucose pyrophosphorylase (AGPase). Adenosine-5′-diphosphoglucose disodium salt is a substrate for starch synthase, α-1,4-glucan-protein synthase, and ADP-glucose pyrophosphorylases, as well as many glucosyltransferases. Adenosine-5′-diphosphoglucose disodium salt is also known as ADPG, ADP-glc, ADP-Glucose, ADP-Glucose Sodium Salt, P′-β-D-Glucopyranosyl Ester Adenosine 5′-(Trihydrogen Diphosphate) Disodium Salt, ADP-Glucose Disodium, ADP-glc Disodium, ADPG Disodium, and ADP-D-Glucose Disodium Salt.
