Alkyl monoglucosides sun ƙunshi naúrar D-glucose guda ɗaya.Tsarin zobe suna kama da raka'o'in D-glucose.Dukansu zoben membobi biyar da shida waɗanda suka haɗa da atom ɗin oxygen ɗaya kamar yadda heteroatom ke da alaƙa da tsarin furan ko pyran.Alkyl D-glucosides tare da zoben membobi biyar don haka ana kiran su alkyl d-glucofuranosides, da waɗanda ke da zoben memba shida, alkyl D-glucopyranosides.

Duk raka'o'in D-glucose suna nuna aikin acetal wanda atom ɗin carbon shine kawai wanda za'a haɗa shi da ƙwayoyin oxygen guda biyu.Ana kiran wannan anomeric carbon atom ko cibiyar anomeric.Abin da ake kira glycosidic bond tare da ragowar alkyl, da kuma haɗin gwiwa tare da atom na oxygen na zoben saccharide, ya samo asali daga anomeric carbon atom.Don daidaitawa a cikin sarkar carbon, atom ɗin carbon na rukunin D-glucose ana ƙididdige su gabaɗaya (C-1 zuwa C-6) suna farawa da atom ɗin carbon anomeric.Ana ƙididdige ƙwayoyin oxygen gwargwadon matsayinsu a sarkar (O-1 zuwa O-6).An maye gurbin zarra na carbon anomeric da asymmetrically don haka yana iya ɗaukar saiti daban-daban guda biyu.Sakamakon stereoisomers ana kiran su anomers kuma an bambanta su da prefix α ko β.Dangane da ƙa'idodin ƙa'idodin ƙa'idodin ƙa'idodi sun nuna cewa ɗayan yuwuwar daidaitawa biyu waɗanda haɗin gwiwar glycosidic ya nuna dama a cikin tsarin tsinkayar Fischer na glucosides.Daidai akasin haka yake ga masu anma.

A cikin jerin sunayen sunadarai na carbohydrate, sunan alkyl monoglucoside ya ƙunshi kamar haka: Ƙayyadaddun ragowar alkyl, ƙaddamar da tsarin anomeric, ma'anar "D-gluc," nadi nau'in cyclic, da ƙari na ƙarewa " oside."Tunda halayen sinadarai a cikin saccharides yawanci suna faruwa ne a atom ɗin carbon atom ko atom ɗin oxygen na ƙungiyoyin farko ko na biyu na hydroxyl, daidaitawar atom ɗin carbon asymmetrical ba ya canzawa koyaushe, sai a cikin cibiyar anomeric.A wannan yanayin, da nomenclature ga alkyl glucosides yana da matukar amfani, tun da syllable "D-gluc" na iyaye saccharide D-glucose yana riƙe a cikin taron da yawa na kowa nau'i na halayen da gyare-gyaren sinadarai za a iya kwatanta su da suffixes.

Kodayake tsarin tsarin saccharide nomenclature na iya haɓaka mafi kyau bisa ga ka'idodin tsinkayar Fischer, ƙirar Haworth tare da wakilcin sarkar carbon gabaɗaya an fi son su azaman tsarin tsarin saccharide.Hasashen Haworth yana ba da mafi kyawun ra'ayi game da tsarin kwayoyin halitta na rukunin D-glucose kuma an fi so a cikin wannan bita.A cikin tsarin Haworth, atom ɗin hydrogen da ke da alaƙa da zoben saccharide galibi ba a gabatar da su ba.
