'''Hydrolysis''' (/haɪˈdrɒlɪsɪs/; from Ancient Greek ''hydro-'' 'water', and ''lysis'' 'to unbind') is a chemical reaction in which a molecule of water breaks one or more chemical bonds. The term is used broadly for substitution, elimination, and solvation reactions in which water is the nucleophile.<ref>{{Cite web|year=2002|title=Hydrolysis|e-pub date=2002|date accessed=2021|url=https://en.wikipedia.org/wiki/Hydrolysis|Author=Wikipedia}}</ref> In lignocellulosic biomass, the cellulose and hemicellulose breaks down into individual sugars, where hemicellulose is easier to hydrolyse than cellulose.<ref>{{Cite journal|title=Dilute acid hydrolysis of lignocellulosic biomass|year=2010-01-15|author=P.
