In [[enzymology]], a '''glucose 1-dehydrogenase (FAD, quinone)''' ({{EC number|1.1.5.9}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:D-glucose + a quinone <math>\rightleftharpoons</math> D-glucono-1,5-lactone + a quinol

Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[D-glucose]] and a quinone, whereas its two [[product (chemistry)|products]] are [[Glucono delta-lactone|D-glucono-1,5-lactone]] and a quinol.

This enzyme belongs to the family of [[oxidoreductase]]s, specifically those acting on the CH-OH group of donor with other acceptors. The [[List of enzymes|systematic name]] of this enzyme class is '''D-glucose:acceptor 1-oxidoreductase'''. Other names in common use include '''glucose dehydrogenase (''Aspergillus'')''', '''glucose dehydrogenase (decarboxylating)''', and '''D-glucose:(acceptor) 1-oxidoreductase'''. This enzyme participates in [[pentose phosphate pathway]]. It employs one [[cofactor (biochemistry)|cofactor]], [[flavin adenine dinucleotide|FAD]].
