Editing Hydroxy group (section)

==Occurrence==
The hydroxy group is pervasive in chemistry and biochemistry. Many inorganic compounds contain hydroxyl groups, including [[sulfuric acid]], the chemical compound produced on the largest scale industrially.<ref>{{Cite journal |title=Research Report 2012 – 2013 |url=https://www.cup.uni-muenchen.de/site/assets/files/1039/fob_bd_12.pdf |journal=Ludwig Maximilians Universität München Fakultät für Chemie und Pharmazie |volume=12 |url-status=dead |archive-url=https://web.archive.org/web/20221207034402/https://www.cup.uni-muenchen.de/site/assets/files/1039/fob_bd_12.pdf |archive-date= Dec 7, 2022 }}</ref>

Hydroxy groups participate in the dehydration reactions that link simple biological molecules into long chains. The joining of a [[fatty acid]] to [[glycerol]] to form a [[triacylglycerol]] removes the −OH from the carboxy end of the fatty acid. The joining of two [[Aldose|aldehyde sugars]] to form a [[disaccharide]] removes the −OH from the carboxy group at the [[aldehyde]] end of one [[sugar]]. The creation of a [[peptide bond]] to link two [[amino acid]]s to make a [[protein]] removes the −OH from the carboxy group of one amino acid.{{cn|date=April 2024}}
