{{Short description|Class of chemical compounds}} thumb|right|Chemical structure of ''n''-decyl-β-D-maltopyranoside (DM) A '''maltoside''' is a glycoside with maltose as the glycone (sugar) functional group. Among the most common are '''alkyl maltosides''', which contain hydrophobic alkyl chains as the aglycone. Given their amphiphilic properties, these comprise a class of detergents, where variation in the alkyl chain confers a range of detergent properties including CMC and solubility. Maltosides are most often used for the solubilization and purification of membrane proteins.
== History == In 1980 Ferguson-Miller ''et al.'' at Michigan State developed ''n''-dodecyl-β-<small>D</small>-maltopyranoside (DDM) as part of a successful effort to purify an active, stable, monodisperse form of cytochrome c oxidase.<ref>{{cite journal|last1=Rosevear|first1=P|last2=VanAken |first2=T |last3=Baxter |first3=J |last4=Ferguson-Miller |first4=S |title=Alkyl glycoside detergents: a simpler synthesis and their effects on kinetic and physical properties of cytochrome c oxidase.|journal=Biochemistry|date=Aug 19, 1980|volume=19|issue=17|pages=4108–15|pmid=6250583|doi=10.1021/bi00558a032}}</ref> Maltosides have been used extensively to stabilize membrane proteins for biophysical and structural studies.
