Eminyakeni yamuva nje, ukudla kwe-ketogenic kuye kwathandwa ngenxa yekhono lakho lokukhuthaza ukwehlisa isisindo nokuthuthukisa impilo iyonke. Lokhu kudla okunama-carbohydrate aphansi, okunamafutha amaningi kuphoqa umzimba ukuba ube sesimweni se-metabolic esibizwa ngokuthi i-ketosis. Ngesikhathi se-ketosis, umzimba ushisa amafutha esikhundleni sama-carbohydrate, okuholela ekulahlekelweni kwamafutha kanye namazinga aphezulu amandla. Nakuba ukulandela ukudla kwe-ketogenic kuphumelela kakhulu, abantu abaningi banobunzima bokufeza nokugcina i-ketosis. Yilapho izithasiselo ze-ketone ester ziqala khona ukusebenza. Ngokuthatha izithasiselo ze-ketone ester, abantu bangakwazi ukuvusa nokugcina i-ketosis ngokushesha nangokuphumelelayo. Lokhu kusho ukuthi noma ngabe udla ama-carbohydrate amaningi kunokunconywayo ngengozi, ama-ketone ester angakusiza ukuthi ubuyele ku-ketosis ngokushesha. Ngaphezu kwalokho, izithasiselo ze-ketone ester zinikeza umthombo wamandla osheshayo ongathuthukisa kakhulu ukusebenza kwezemidlalo kanye nokukhuthazela okuphelele.
Ukuze siqonde ukuthi ayini ama-ketone ester, okokuqala kufanele siqonde ukuthi ayini ama-ketone nokuthi ayini ama-ester.
Ama-Ketones amakhemikhali akhiqizwa esibindini sethu akhiqizwa yimizimba yethu uma singenawo amazinga anele e-glucose yokudla yangaphandle noma i-glycogen egciniwe ukuze iguqulwe ibe amandla. Phakathi kwawo,isibindi siguqula amafutha abe ama-ketone bese siwahambisa egazini ukuze asetshenziswe njengamafutha emisipha,ubuchopho, nezinye izicubu.
I-ester iyinhlanganisela ephendulana namanzi ukuze yakhe i-alcohol kanye ne-organic noma i-inorganic acid. Ama-ketone ester akhiwa lapho ama-molecule e-alcohol ehlangana nemizimba ye-ketone. Ama-ketone ester aqukethe i-beta-hydroxybutyrate (BHB) eningi, enye yemizimba emithathu ye-ketone ekhiqizwa abantu. I-BHB iwumthombo oyinhloko wamafutha asekelwe ku-ketone.
Ama-ester e-ketone ayizakhi eziqukethe iqembu le-ketone, okuyiqembu elisebenzayo elibonakala ngokuba khona kwe-athomu yekhabhoni ehlanganiswe kabili ne-athomu ye-oxygen. Ahlukile kwimizimba ye-ketone evame kakhulu, ekhiqizwa yisibindi ngesikhathi sokuzila ukudla isikhathi eside noma ukuvinjelwa kwama-carbohydrate. Nakuba imizimba ye-ketone nama-ester e-ketone anezakhiwo zamakhemikhali ezifanayo, anemiphumela ehlukene kakhulu emzimbeni.
Ama-ester e-ketone, ngokuvamile ngesimo seziphuzo noma izithasiselo, aguqulwa yisibindi futhi akhuphula ngokushesha amazinga e-ketone egazini. Amazinga aphezulu e-ketone egazini abangela isimo se-ketosis, lapho umzimba ushintsha khona umthombo wawo oyinhloko wamafutha kusuka ku-glucose uye kuma-ketone. Ama-ketone awumthombo wamandla ohlukile okhiqizwa umzimba lapho ukutholakala kwama-carbohydrate kulinganiselwe, okuvumela ukuthi ushise amafutha ngempumelelo njengophethiloli.
Ama-ketone esters anikeza izinzuzo eziningana ezingaba khona uma kukhulunywa ngokusebenza kahle kwezemidlalo. Okokuqala, ama-ketone angumthombo wamafutha osebenza kahle kakhulu wemisipha nobuchopho ngoba ama-ketone angasetshenziswa ngokushesha futhi anikeze isivuno samandla amakhulu ngeyunithi ngayinye yomoya-mpilo uma kuqhathaniswa ne-glucose.
Okokuqala, ake sibheke kabanzi izakhiwo zama-ester nama-ketone. Ama-ester akhiwa ukusabela phakathi kwama-carboxylic acid nama-alcohols. Aqukethe amaqembu e-carbonyl ahlanganiswe nama-athomu e-oxygen ne-carbon. Ama-ketone, ngakolunye uhlangothi, akhiwa iqembu le-carbonyl elixhunywe kuma-athomu amabili e-carbon. Lo mehluko wesakhiwo ungomunye wemehluko eyisisekelo phakathi kwama-ester nama-ketone.
Omunye umehluko obalulekile usezinhlotsheni zawo zokusebenza. Ama-Ester aqukethe ukusebenza kwe-ester, okubonakala ngesibopho esiphindwe kabili se-carbon-oxygen kanye ne-athomu ye-oxygen exhunywe kwi-athomu ye-carbon ngesibopho esisodwa. Ngokuphambene nalokho, ama-ketone anokusebenza kwe-ketone futhi aqukethe izibopho eziphindwe kabili ze-carbon-oxygen ngaphakathi kwe-skeleton yawo ye-carbon.
Ngaphezu kwalokho, izakhiwo zomzimba zama-ester nama-ketone ziyahluka. Ama-ester avame ukuba nephunga elimnandi lezithelo, yingakho evame ukusetshenziswa njengephunga elimnandi kuma-perfume nanjengezinongo ekudleni. Ama-ketone, ngakolunye uhlangothi, awanalo iphunga elihlukile. Ngokombono wokuncibilika, ama-ester ngokuvamile ayancibilika kuma-solvent e-organic futhi awancibiliki emanzini. Ngokuphambene nalokho, ama-ketone ngokuvamile ayancibilika emanzini nakuma-solvent e-organic. Lo mehluko ekuncibilikeni unikeza ama-ester nama-ketone izinsiza ezibalulekile eziwusizo ezimbonini ezahlukene.
Ama-Esters nama-ketone asabela ngendlela ehlukile lapho ebhekana nokusabela kokwengeza kwe-nucleophilic. Ama-Esters asengozini enkulu yokuhlaselwa yi-nucleophilic ngenxa yokuba khona kwezibopho ezimbili ze-carbon-oxygen. Ukusabela kuvame ukuhilela ukuqhekeka kwezibopho ze-carbon-oxygen kanye nokwakheka kwezibopho ezintsha nama-nucleophiles. Ama-Ketone, ngakolunye uhlangothi, awasabeli kangako ekuphenduleni kokwengeza kwe-nucleophilic. Lokhu kungenxa yokuthi ukuba khona kwamaqembu amabili e-alkyl ahlanganiswe ne-carbonyl carbon kunciphisa i-electrophilicity ye-ketone, okwenza kube lula ukusabela nama-nucleophiles.
Ama-Ketone nama-ester anezindlela ezahlukene zokusetshenziswa ngenxa yezindlela ezahlukene zokusetshenziswa. Ama-Ester asetshenziswa kabanzi embonini yamakha nephunga ngenxa yephunga lawo elimnandi nokunambitheka kwawo. Asetshenziswa futhi njengezinto zokuhlanza, izithasiselo zepulasitiki, kanye nezinto zokusetshenziswa ekukhiqizweni kwemithi nezimonyo. Ama-Ketone, ngakolunye uhlangothi, anezindlela eziningi zokusetshenziswa ezimbonini ezahlukene, okuhlanganisa njengezinto zokuhlanza, izinto zokuvuselela ukusabela, kanye nezinto ezibangela ukwakheka kwemithi kanye namakhemikhali ezolimo.
