{{main|Glucose oxidation reaction}}
The enzyme glucose oxidase (GOx) converts glucose into gluconic acid and hydrogen peroxide while consuming oxygen. Another enzyme, peroxidase, catalyzes a chromogenic reaction (Trinder reaction)<ref>{{Cite journal |doi=10.1177/000456326900600108 |title=Determination of Glucose in Blood Using Glucose Oxidase with an Alternative Oxygen Acceptor |journal=Annals of Clinical Biochemistry |volume=6 |pages=24–27 |year=1969 |last1=Trinder |first1=P. |issue=1 |s2cid=58131350 |doi-access=free }}</ref> of [[phenol]] with [[4-Aminoantipyrine|4-aminoantipyrine]] to a purple dye.<ref name="purpuled">{{cite book |doi=10.1016/bs.pmbts.2019.01.004 |chapter=Fasting blood glucose levels in patients with different types of diseases |title=Glycans and Glycosaminoglycans as Clinical Biomarkers and Therapeutics - Part A |series=Progress in Molecular Biology and Translational Science |date=2019 |volume=162 |pages=277–292 |isbn=978-0-12-817738-9 | vauthors = Zhang Q, Zhao G, Yang N, Zhang L |publisher=Elsevier |pmid=30905457 }}</ref>
