Siza uchaze ukuthi iyini uwoyela bese unginika uhlu lwezinto ozisebenzisayo.
Context:Uwoyela yinoma iyiphi into yamakhemikhali engeyona i-polar eyakhiwe ngokuyinhloko ngama-hydrocarbon futhi i-hydrophobic (ayihlangani namanzi) ne-lipophilic (ihlangana namanye amafutha). Ngokuvamile amafutha ayashisa futhi asebenza ebusweni. Iningi lamafutha liyi - lipid engaxutshiwe engamanzi ekamelweni.  Incazelo ejwayelekile kawoyela ihlanganisa izigaba zamakhemikhali okungenzeka ukuthi awuhlobene ngokwakheka, izakhiwo, nokusetshenziswa. Amafutha angase abe ezilwane, ezitshalo, noma ama-petrochemical, futhi angase abe aphephile noma angaphephile. Zisetshenziselwa ukudla (isib., uwoyela womnqumo), uphethiloli (isib., uwoyela wokushisa), izinjongo zezokwelapha (isib., uwoyela wamaminerali), ukuthambisa (isib., uwoyela wezimoto), nokwenziwa kwezinhlobo eziningi zamapende, amapulasitiki nezinye izinto. Amafutha alungiselelwe ngokukhethekile asetshenziswa emikhosini ethile yenkolo nemikhuba njengamafutha okuhlanza.
Uwoyela uyisimo samakhemikhali esakhiwe ngokuyinhloko ngama-hydrocarbon futhi singaba sesilwane, semifino noma se-petrochemical. Uwoyela usetshenziswa ezindaweni eziningi futhi ubalulekile ekuphileni kwabantu kwansuku zonke. Lezi zindlela yilezi: Ukupheka - amafutha adliwayo emifino nawezilwane asetshenziselwa izinjongo ezihlukahlukene ekuphekeni nasekulungiseleleni ukudla Imikhiqizo yezimonyo - iningi lemikhiqizo yokuhlanza ubuso, ama-lotion nemikhiqizo yokunakekela izinwele iqukethe ama-molecule avela kumafutha amaminerali nawemifino Amafutha - uwoyela ongahluziwe ugaywa ube idizili, uphethiloli noma uphethiloli wezindiza ukuze usebenze ngezimoto, amaloli nezindiza Ukushisa - uwoyela we-petrochemical usetshenziselwa ukushisa Umdwebo - uwoyela usetshenziswa njengesisekelo somdwebo Amafutha okuthambisa asetshenziselwa izinhloso ezahlukahlukene zobunjiniyela njengoba engabambeleli kalula kwezinye izinto ezenza ukuthi zisetshenziswe njengamafutha okuthambisa Inkolo - amafutha aye asetshenziswa kuwo wonke umlando njengendlela yenkolo. Ngokuvamile kubhekwa njengento ehlanzayo ngokomoya futhi isetshenziselwa ukugcoba Amafutha anempilo aqukethe amafutha amaningi nezakhiwo zokwelapha, isibonelo amafutha ezinhlanzi aqukethe i-omega-3 fatty acid esiza ekuvuvukeni futhi sinciphise amafutha egazini
