Ushukela igama elejwayelekile lokunambitha okumnandi, ama-carbohydrate ancibilikayo, amaningi awo asetshenziswa ekudleni. Ushukela wethebula, ushukela ohlanganisiwe, noma ushukela ojwayelekile, kubhekisa ku-sucrose, i-disaccharide eyenziwe nge-glucose ne-fructose. Ushukela olula, obizwa nangokuthi i-monosaccharides, kufaka phakathi i-glucose, i-fructose ne-galactose. Ushukela oyinhlanganisela, obizwa nangokuthi ama-disaccharides noma ushukela ophindwe kabili, ngama-molecule akhiwa ama-monosaccharides amabili ajoyine isibopho se-glycosidic. Izibonelo ezivamile yi-sucrose (ushukela wetafula) (i-glucose + fructose), i-lactose (i-glucose + galactose), ne-maltose (ama-molecule amabili we-glucose). Emzimbeni, ushukela ohlangene uhanjiswa ngamanzi ushukela olula. Amaketanga amade ama-monosaccharides awathathwa njengoshukela, futhi abizwa ngama-oligosaccharides noma ama-polysaccharides. Isitashi yi-glucose polymer etholakala ezitshalweni, futhi ingumthombo wamandla amaningi kakhulu ekudleni kwabantu. Ezinye izinto zamakhemikhali, njenge-glycerol noshukela alcohol, zingaba nokunambitheka okumnandi, kepha azihlukaniswa njengoshukela. Ushukela utholakala ezicutshini zezitshalo eziningi. Uju nezithelo yimithombo eminingi yemvelo kashukela olula ongenamkhawulo. I-Sucrose igxile kakhulu ezimobeni nasesithombo sebhitrudi, ibenze balungele ukukhishwa kahle kwezentengiselwano ukwenza ushukela ocwengekile. Ngo-2016, ukukhiqizwa komhlaba okuhlangene kwalezo zilimo ezimbili kwakungamathani ayizigidi eziyizinkulungwane ezimbili.
