Editing Disaccharide (section)

==Formation==
The formation of a disaccharide molecule from two [[monosaccharide]] molecules proceeds by displacing a [[hydroxy group]] from one molecule and a [[Hydrogen atom|hydrogen nucleus]] (a [[proton]]) from the other, so that the new vacant bonds on the monosaccharides join the two [[monomer]]s together. Because of the removal of the water molecule from the product, the term of convenience for such a process is "[[dehydration reaction]]" (also "[[condensation reaction]]" or "[[Dehydration reaction|dehydration synthesis]]"). For example, milk sugar (lactose) is a disaccharide made by condensation of one molecule of each of the monosaccharides [[glucose]] and [[galactose]], whereas the disaccharide sucrose in sugar cane and sugar beet, is a condensation product of glucose and [[fructose]]. [[Maltose]], another common disaccharide, is condensed from two glucose molecules.<ref>{{cite book |last=Whitney |first=Ellie |url=https://archive.org/details/understandingnu000whit |title=Understanding Nutrition |author2=Sharon Rady Rolfes |publisher=Wadsworth, Cengage Learning |year=2011 |isbn=978-0-538-73465-3 |editor=Peggy Williams |edition=Twelfth |location=California |pages=100 |url-access=registration}}</ref>

The dehydration reaction that bonds monosaccharides into disaccharides (and also bonds monosaccharides into more complex [[polysaccharide]]s) forms what are called glycosidic bonds.<ref name="ochempal">{{cite web |title=Glycosidic Link |url=http://science.uvu.edu/ochem/index.php/alphabetical/g-h/glycosidic-link/ |archive-url=https://web.archive.org/web/20130512002153/http://science.uvu.edu/ochem/index.php/alphabetical/g-h/glycosidic-link/ |archive-date=May 12, 2013 |access-date=11 December 2013 |website=OChemPal |publisher=Utah Valley University}}</ref>
