Eminyakeni yamuva, ukudla kwe-ketogenic kuye kwazuza ukuthandwa ngenxa yekhono layo lokukhuthaza ukulahlekelwa isisindo nokuthuthukisa impilo yonke. Lokhu kudla okune-carb ephansi, okunamafutha amaningi kuphoqa umzimba ukuba ube sesimweni sokugayeka kokudla esibizwa nge-ketosis. Ngesikhathi se-ketosis, umzimba ushisa amafutha ukuze uthole uphethiloli esikhundleni sama-carbohydrate, okuholela ekulahlekelweni kwamafutha kanye namazinga wamandla anda. Nakuba ukulandela ukudla kwe-ketogenic kusebenza kakhulu, abantu abaningi banenkinga yokufeza nokugcina i-ketosis. Yilapho izithasiselo ze-ketone ester zingena khona. Ngokuthatha izithasiselo ze-ketone ester, abantu bangayenga futhi balondoloze i-ketosis ngokushesha nangempumelelo kakhudlwana. Lokhu kusho ukuthi noma udla ngephutha ama-carbs amaningi kunalokho okunconyiwe, i-ketone esters ingakusiza ukuthi ubuyele ku-ketosis ngokushesha. Ukwengeza, izithako ze-ketone ester zinikeza umthombo wamandla osheshayo ongathuthukisa kakhulu ukusebenza kwezemidlalo nokukhuthazela okuphelele.
Ukuze siqonde ukuthi i-ketone esters iyini, okokuqala kufanele siqonde ukuthi ayini ama-ketones nokuthi ayini.
Ama-ketone angamakhemikhali akhiqizwa esibindini sethu akhiqizwa imizimba yethu lapho singenawo amanani anele eglucose yokudla yangaphandle noma i-glycogen egciniwe ukuze iguqule ibe amandla. Phakathi kwazo,isibindi siguqula amafutha abe ama-ketone futhi awahambise egazini ukuze asetshenziswe njengophethiloli wemisipha,ubuchopho, nezinye izicubu.
I-ester iyinhlanganisela esabela emanzini ukuze yakhe utshwala kanye ne-organic noma i-inorganic acid. I-Ketone esters yakheka lapho ama-molecule e-alcohol ehlangana nemizimba ye-ketone. I-Ketone esters iqukethe i-beta-hydroxybutyrate (BHB) eyengeziwe, enye yemizimba emithathu ye-ketone ekhiqizwa abantu. I-BHB iwumthombo oyinhloko wamafutha asekelwe kwi-ketone.
I-Ketone esters yizinhlanganisela eziqukethe iqembu le-ketone, okuyiqembu elisebenzayo elibonakala ngokuba khona kwe-athomu ye-carbon ehlanganiswe kabili ku-athomu ye-oxygen. Zihlukile emizimbeni ye-ketone evamile, ekhiqizwa isibindi ngezikhathi zokuzila ukudla isikhathi eside noma ukuvinjelwa kwama-carbohydrate. Nakuba imizimba ye-ketone kanye ne-ketone esters inezakhiwo zamakhemikhali ezifanayo, zinemiphumela ehluke kakhulu emzimbeni.
I-Ketone esters, ngokuvamile ngendlela yeziphuzo noma izithasiselo, i-metabolized yisibindi futhi ikhuphule ngokushesha amazinga e-ketone yegazi. Amazinga e-ketone egazi aphakeme abangela isimo se-ketosis, lapho umzimba ushintsha umthombo wawo wamafutha oyinhloko usuka ku-glucose uye kuma-ketone. Ama-ketones angumthombo wamandla ohlukile okhiqizwa umzimba lapho ukutholakala kwama-carbohydrate kunqunyelwe, okuwuvumela ukuthi ashise ngempumelelo amafutha ukuze abe uphethiloli.
I-Ketone esters inikeza izinzuzo ezimbalwa ezingaba khona uma kuziwa ekusebenzeni kwezemidlalo. Okokuqala, ama-ketone awumthombo wamafutha osebenza kahle kakhulu wemisipha nobuchopho ngoba ama-ketone angasetshenziswa ngokushesha futhi anikeze isivuno esikhulu samandla ngeyunithi ngayinye yomoya-mpilo uma kuqhathaniswa neglucose.
Okokuqala, ake sihlolisise izakhiwo zama-esters nama-ketones. Ama-Ester akhiwa ukusabela phakathi kwama-carboxylic acid nama-alcohol. Aqukethe amaqembu e-carbonyl ahlanganiswe nomoya-mpilo nama-athomu e-carbon. Ama-ketones, ngakolunye uhlangothi, akhiwa iqembu le-carbonyl elixhunywe kuma-athomu e-carbon amabili. Lo mehluko wesakhiwo ungomunye wemehluko obaluleke kakhulu phakathi kwama-esters nama-ketones.
Omunye umehluko obalulekile usemaqenjini abo asebenzayo. Ama-Ester aqukethe ukusebenza kwe-ester, okubonakala ngebhondi ye-carbon-oksijeni ephindwe kabili kanye ne-athomu yomoya-mpilo eboshwe ku-athomu ye-carbon ngebhondi eyodwa. Ngokuphambene, ama-ketone anokusebenza kwe-ketone futhi aqukethe izibopho eziphindwe kabili ze-carbon-oxygen ngaphakathi kwamathambo awo e-carbon.
Ukwengeza, izakhiwo ezingokomzimba zama-esters nama-ketones ziyehluka. Ama-Ester avame ukuba namaphunga amnandi anezithelo, yingakho evame ukusetshenziswa njengamakha kumakha nanjengokunandisa ekudleni. Ngakolunye uhlangothi, ama-ketones awanalo iphunga elihlukile. Ngokombono wokuncibilika, ama-ester ngokuvamile ayancibilika kuzincibilikisi zemvelo futhi awancibiliki emanzini. Ngokuphambene, ama-ketones ngokuvamile ayancibilika emanzini nasezincibilikisini eziphilayo. Lo mehluko ku-solubility unikeza ama-esters nama-ketone ngezicelo ezibalulekile ezisebenzayo ezimbonini ezihlukahlukene.
Ama-ester nama-ketone asabela ngendlela ehlukile lapho ehlangabezana nokusabela kokungezwa kwe-nucleophilic. Ama-Esters asengozini enkulu yokuhlaselwa yi-nucleophilic ngenxa yokuba khona kwe-carbon-oxygen double bond. Ukusabela ngokuvamile kuhilela ukugqashuka kwebhondi ye-carbon-oxygen kanye nokwakhiwa kwezibopho ezintsha nama-nucleophile. Ama-ketones, ngakolunye uhlangothi, awasebenzi kangako ekuphenduleni kokungezwa kwe-nucleophilic. Lokhu kungenxa yokuthi ukuba khona kwamaqembu amabili e-alkyl ahlanganiswe ne-carbonyl carbon kunciphisa i-electrophilicity ye-ketone, okwenza kube mancane amathuba okusabela ngama-nucleophile.
Ama-ketones nama-ester anokusetshenziswa okuhlukile ngenxa yezinhlelo zokusebenza ezahlukene. Ama-Ester asetshenziswa kakhulu embonini yephunga nephunga ngenxa yephunga elimnandi nokunambitha. Zibuye zisetshenziswe njengezincibilikisi, izithasiselo zepulasitiki, nezinto zokusetshenziswa ekukhiqizeni imithi nezimonyo. Ngakolunye uhlangothi, ama-ketones anezinhlobonhlobo zokusetshenziswa ezimbonini ezihlukahlukene, okuhlanganisa njengama-solvents, ama-reaction intermediate, nama-precursors ekuhlanganiseni kwemithi kanye namakhemikhali e-agrochemicals.
