Okokuqala, ake siqale siqonde ukuthi i-ketone esters iyini.I-Ketone esters yizinhlanganisela ezitholakala emizimbeni ye-ketone, ekhiqizwa isibindi ngezikhathi zokuzila ukudla noma ukudla okuphansi kwe-carbohydrate.Lezi zinhlanganisela zingasetshenziswa njengomthombo ohlukile kaphethiloli womzimba, ikakhulukazi ngezikhathi zokwanda kwesidingo samandla, njengalapho uzivocavoca.Lapho umzimba uku-ketosis, usebenzisa amafutha ukuze uthole amandla ngokuphumelelayo, ngaleyo ndlela uthuthukise ukukhuthazela futhi unciphise ukuthembela ezitolo ze-glycogen.
Okokuqala, ake sihlukanise igama elithi “ketone ester.”Ama-ketones ayizinhlanganisela eziphilayo ezikhiqizwa isibindi lapho umzimba usesimweni se-ketosis, okwenzeka lapho umzimba ushisa amanoni esikhundleni sama-carbohydrate ukuze abe uphethiloli.I-Ketone esters, ngakolunye uhlangothi, yizinhlanganisela zokwenziwa ezilingisa imiphumela ye-ketosis, ihlinzeka umzimba ngomthombo oqondile wamandla ngendlela yama-ketones.
Ngakho-ke, yini eyenza i-ketone esters ibe namandla kangaka?Enye yezinzuzo eziyinhloko ze-ketone esters yikhono layo lokwandisa ngokushesha amazinga e-ketone yegazi, ukunikeza umzimba umthombo wamandla osheshayo futhi ophumelelayo.Lokhu kunenzuzo ikakhulukazi kubasubathi kanye nabantu abafuna ukuthuthukisa ukusebenza kwabo ngokomzimba, njengoba ama-ketones angasetshenziswa njengamafutha ahlanzekile emisipha nobuchopho, ngaleyo ndlela akhulise ukukhuthazela, ukunciphisa ukukhathala, nokuthuthukisa ukululama.Ngaphandle kwemiphumela yabo yokuthuthukisa ukusebenza, i-ketone esters iboniswe ukuthi inezici ze-neuroprotective.
Ukwengeza, i-ketone esters ifundwe ngendima yabo engaba khona empilweni ye-metabolic, ikakhulukazi ekulawuleni ukukhuluphala kanye nesifo sikashukela.Ngokukhuthaza amandla omzimba okushisa amafutha ngendlela efanele ukuze uthole uphethiloli, i-ketone esters ingasiza ekuthuthukiseni ukuzwela kwe-insulin, ilawule amazinga kashukela egazini futhi ikhuthaze ukuncipha kwesisindo.
Okokuqala, siqala ngama-esters.Ama-Ester ayizinhlanganisela eziphilayo ezakhiwe lapho utshwala busabela ne-carboxylic acid.Lokhu kusabela kuphumela ekwakhekeni kwe-molecule ene-carbon-oxygen double bond (C=O) kanye ne-oxygen single bond nenye i-athomu ye-carbon.Ama-Ester aziwa ngephunga lawo elimnandi, elinezithelo futhi avame ukusetshenziswa ekukhiqizeni iziqholo nezinongo.
Ama-ketones, ngakolunye uhlangothi, ayizinhlanganisela eziphilayo eziqukethe iqembu le-carbonyl (C=O) elihlanganiswe nama-athomu ekhabhoni amabili.Ngokungafani nama-esters, ama-ketone awanayo i-athomu ye-hydrogen ehlanganiswe nekhabhoni ye-carbonyl.Ama-ketones avame ukutholakala emvelweni futhi abuye asetshenziswe ezinhlobonhlobo zezimboni nezentengiso.
Umehluko owodwa omkhulu phakathi kwama-esters nama-ketone yisakhiwo sawo samakhemikhali namaqembu asebenzayo.Nakuba zombili izinhlanganisela ziqukethe iqembu le-carbonyl, indlela iqembu le-carbonyl elihlangana ngayo kwamanye ama-athomu iwenza ahluke kwelinye.Ku-esters, iqembu le-carbonyl lihlanganiswe ne-athomu eyodwa ye-oxygen kanye ne-athomu ye-carbon eyodwa, kuyilapho kuma-ketone, iqembu le-carbonyl lihlanganiswe nama-athomu ekhabhoni amabili.
Omunye umehluko obalulekile phakathi kwama-esters nama-ketones wukusebenza kwawo kabusha kanye nezakhiwo zamakhemikhali.Ama-Ester aziwa ngephunga lawo elimnandi futhi avame ukusetshenziswa njengama-condiments nezinongo.Futhi banamaphuzu aphansi abilayo uma kuqhathaniswa nama-ketones.Ama-ketones, ngakolunye uhlangothi, anephuzu eliphezulu lokubila futhi asebenza kakhulu ngenxa yokuba khona kweqembu le-carbonyl elihlanganiswe nama-athomu ekhabhoni amabili.
Ngokusetshenziswa kwawo, ama-esters nama-ketone anezinhlelo zokusebenza ezihlukene.Ama-Ester avame ukusetshenziswa ekukhiqizeni amakha, ama-flavour nezimonyo, kuyilapho ama-ketone asetshenziswa ezincibilikisayo, emithini yemithi nasezinqubweni zezimboni.Ukuqonda izakhiwo eziyingqayizivele kanye nokusebenza kabusha kwalezi zinhlanganisela kubalulekile ekusebenzeni kwazo okuhlukahlukene.
I-Autophagy iyinqubo yeselula lapho amangqamuzana esula ama-organelles alimele namaprotheni ukuze alondoloze impilo.Kukholakala ukuthi ukuvuselela i-autophagy kungase kube nohlu lwezinzuzo zezempilo ezingase zibe khona, njengokwelula isikhathi sokuphila, ukunciphisa ingozi yezifo ezithile, nokusekela ukusebenza kwamaselula jikelele.Ama-ketones, ngakolunye uhlangothi, ayizinhlanganisela ezikhiqizwa lapho umzimba ugaya amafutha ukuze uthole amandla lapho engekho ama-carbohydrates anele.Zixhunyaniswe nezinzuzo zezempilo ezahlukahlukene, okubandakanya ukucaca kwengqondo okuthuthukisiwe, ukuncipha kwesisindo, kanye nempilo ye-metabolic.
Ucwaningo lubonisa ukuthi ama-ketones angaba neqhaza ekuthuthukiseni i-autophagy.Ucwaningo olushicilelwe kumagazini wathola ukuthi ama-ketones, ikakhulukazi i-beta-hydroxybutyrate (BHB), angakwazi ukusebenzisa ngokuqondile izindlela kumaseli anesibopho sokuqalisa nokulawula i-autophagy.Lokhu kuphakamisa ukuthi amazinga e-ketone aphakeme abangelwa ukudla kwe-ketogenic noma isikhathi sokuzila ukudla angase asekele inqubo yemvelo ye-autophagy yomzimba.
Ukwengeza, ama-ketones aboniswe ukuthi athinta ukubonakaliswa kwezakhi zofuzo ezithile namaprotheni ahilelekile ku-autophagy.Kwesinye isifundo, abacwaningi bathola ukuthi i-BHB ilawula ukubonakaliswa kwezakhi zofuzo ezihlobene ne-autophagy kumangqamuzana ezinzwa, okuphakamisa ukuthi kungase kube nendima ekuthuthukiseni le nqubo yeselula.
Ngaphezu kwalokho, ama-ketone atholakala enezinto zokulwa nokuvuvukala kanye ne-antioxidant, zombili ezihlobene kakhulu nenqubo ye-autophagy.Ukuvuvukala okungapheli kanye nokucindezeleka okwenziwe nge-oxidative kuphazamisa i-autophagy, okuholela ekuqoqweni kwezingxenye zamangqamuzana ezilimele futhi kungase kube nomthelela ekuthuthukiseni izifo ezihlukahlukene.Ngokunciphisa ukuvuvukala nokucindezeleka okwenziwe nge-oxidative, ama-ketones asekela ikhono lomzimba lokwenza i-autophagy ngokuphumelelayo nokugcina impilo yeselula.
Kodwa-ke, kubalulekile ukuqaphela ukuthi nakuba ama-ketone angase abe namandla okwandisa i-autophagy, indawo ekhiqizwa kuyo ibalulekile.Isibonelo, amazinga e-ketone aphakeme ngokusebenzisa i-ketosis yokudla okunomsoco, ukuzila ukudla, noma i-ketone supplementation exogenous ingase isekele i-autophagy, kuyilapho ama-ketones akhiqizwa ngenxa yesifo sikashukela esingalawuleki (i-diabetesic ketoacidosis) ayinazo izinzuzo zezempilo ezifanayo ezikhuthaza imiphumela futhi zingase zibe yingozi.
I-Ketone esters yizinhlanganisela eziqukethe iqembu le-ketone, okuyiqembu elisebenzayo eliqukethe iqembu le-carbonyl (C=O) elihlanganiswe nama-athomu ekhabhoni amabili.Lapho zidliwe, lezi zinhlanganisela ziguqulwa ngokushesha zibe ama-ketone, okungama-molecule abalulekile asebenza njengomthombo wamandla ohlukile womzimba nengqondo, ikakhulukazi ngezikhathi zokusetshenziswa kwe-carbohydrate ephansi.Lokhu kwenza i-ketone esters ibe yisinqumo esidumile kubantu abalandela ukudla kwe-ketogenic noma abafuna ukuthuthukisa ukusebenza komzimba nengqondo.
Kunezinhlobo eziningi ze-ketone esters emakethe, ngayinye enezici zayo ezihlukile kanye nokusetshenziswa okungenzeka.Ezinye zezinhlobo ezivame kakhulu zihlanganisa:
1.I-Acetoacetate: I-acetoacetate cishe iwuhlobo oludume kakhulu lwe-ketone ester.Ngokuvamile etholakala ku-acetoacetate, aziwa ngokukwazi kwawo ukuphakamisa ngokushesha amazinga e-ketone yegazi, anikeze umthombo osheshayo wamandla emzimbeni nasengqondweni.Abasubathi nabantu ngabanye bavame ukusebenzisa i-acetoacetate ukuze bathuthukise ukusebenza kwabo ngokomzimba nokukhuthazela.
2.I-Beta-hydroxybutyrate: I-Beta-hydroxybutyrate (BHB) ingenye uhlobo oludumile lwe-ketone ester.I-BHB ingenye yemizimba emithathu ye-ketone ekhiqizwa ngesikhathi se-ketosis futhi ibhekwa njengomthombo wamandla ozinzile futhi osebenza kahle kune-acetoacetate.I-BHB esters ivame ukusetshenziswa yilabo abafisa ukusekela ukucaca kwengqondo, ukugxilisa ingqondo, nokusebenza kwengqondo jikelele.
3.I-Mixed Ketone Esters: Amanye ama-ketone esters akhiwe ngenhlanganisela ye-acetoacetate ne-BHB, enikeza indlela elinganiselayo yokwandisa amazinga e-ketone emzimbeni.Lawa ma-ester e-ketone ayi-hybrid aziswa kakhulu ngekhono lawo lokuhlinzeka ngamandla asheshayo naqhubekayo, okuwenza abe inketho eguquguqukayo yohlelo olubanzi lwezinhlelo zokusebenza.
4.I-ketone esters entsha: Eminyakeni yamuva, abacwaningi bebesebenza ekuthuthukiseni i-ketone esters entsha ngokuthuthukiswa kwe-bioavailability nokusebenza.Lawa ma-ketone esters amasha angase athuthukise ukunambitheka, ukubekezelelana nokumuncwa, kuwenze afaneleke kakhulu ukusetshenziswa okuvamile.
Ukuze uqonde izinzuzo ezingaba khona ze-ketone esters, kubalulekile ukuqonda kuqala ukuthi ziyini.I-Ketone esters yizinhlanganisela eziqukethe ama-ketone, okungama-molecule ephilayo akhiqizwa isibindi lapho umzimba uku-ketosis.I-Ketosis yenzeka lapho umzimba ushisa amafutha esikhundleni sama-carbohydrate, okungenzeka ngesikhathi sokuzila ukudla, ukuvivinya umzimba isikhathi eside, noma ukudla okune-carbohydrate ephansi.
Esinye sezizathu eziyinhloko ze-ketone esters zenze isithakazelo esikhulu amandla abo okunikeza umzimba umthombo osheshayo wamandla.Lapho umzimba uku-ketosis, ukhiqiza imizimba ye-ketone njengomthombo ohlukile wamafutha ku-glucose.Ngemva kokungenisa, i-ketone esters ingena ngokushesha egazini futhi iguqulwa ibe ama-ketone, angasetshenziswa ngumzimba njengomthombo wamafutha.Lokhu kunenzuzo ikakhulukazi kubasubathi noma abantu abafuna ukuthuthukisa ukusebenza kwabo ngokomzimba, njengoba ama-ketone enikeza uhlobo lwamandla oluhlala isikhathi eside nolusebenza kahle uma kuqhathaniswa ne-glucose.
Ngokungeziwe emandleni abo okwandisa amazinga wamandla, i-ketone esters nayo ifundwe ngemiphumela yabo yokuthuthukisa ingqondo.Ucwaningo lubonisa ukuthi ama-ketones angakwazi ukweqa umgoqo wegazi nobuchopho futhi asetshenziswe ubuchopho njengomthombo wamandla, angasiza ukuthuthukisa ukugxila, ukugxila, nokucaca kwengqondo.Ezinye izifundo zize ziphakamise ukuthi ama-ketone angaba nezakhiwo ze-neuroprotective, okuwenza abe yithuluzi elinamandla lokusekela impilo nokusebenza kobuchopho.
Ukulawulwa kwesisindo kanye nempilo ye-metabolic.Njengoba i-ketone esters ikhuthaza i-ketosis, ingasiza ekunciphiseni isisindo ngokukhuthaza ukushiswa kwamafutha nokunciphisa isifiso sokudla.Ukwengeza, i-ketone esters ingaba nomthelela omuhle emazingeni kashukela egazini kanye nokuzwela kwe-insulin, okubenza babe zuzisa kakhulu kubantu abanesifo sikashukela sohlobo lwe-2 noma i-metabolic syndrome.
Kodwa mhlawumbe enye yezinzuzo ezithakazelisa kakhulu ezingase zibe khona ze-ketone esters yikhono labo lokulingisa imiphumela yokuzila ukudla.Ukuzila ukudla kuboniswe ukuthi kunezinhlobonhlobo zezinzuzo zezempilo, okuhlanganisa impilo ethuthukisiwe ye-metabolic, ukuphathwa kwesisindo, nokuphila isikhathi eside.Ngokuhlinzeka umzimba ngomthombo wama-ketones, i-ketone esters ingase ikwazi ukukhiqiza eminye yemiphumela efanayo yokuzila ukudla ngaphandle kokuzila ukudla ngempela.
I-Ketone esters nayo iyafundelwa amandla abo ekuthuthukiseni impilo yenhliziyo nemithambo yegazi.Olunye ucwaningo lubonisa ukuthi i-ketone esters ingaba nomthelela omuhle emazingeni e-cholesterol nomfutho wegazi, okungase kubenze bazuze empilweni yenhliziyo.Kodwa-ke, ucwaningo olwengeziwe luyadingeka kule ndawo ukuze uqonde ngokugcwele imiphumela ye-ketone esters empilweni yenhliziyo.
Ake siqale sichaze ukuthi iyini i-ketone esters.I-Ketone esters ama-ketone angaphandle angasiza umzimba ukuthi ungene ku-ketosis ngokushesha uma uthathwa njengesengezo.Ngokuvamile zisetshenziswa abasubathi kanye nabantu abafuna indlela yokufeza i-ketosis ngokushesha ngaphandle kokunamathela ngokuqinile ekudleni okune-carb ephansi, okunamafutha amaningi.Ngakolunye uhlangothi, ukudla okungokwesiko kwe-ketogenic, kuhilela isimiso sokudla esiqinile esidinga abantu ngabanye ukuba badle ukudla okunamafutha amaningi anempilo, amaprotheni alinganiselwe, nama-carbohydrate aphansi kakhulu.
I-Ketoesters ibonakala iyindlela ekhangayo kulabo abafuna indlela esheshayo, elula yokufinyelela i-ketosis ngaphandle kokushintsha ngokuphelele ukudla kwabo.Ngokuthatha ama-ketones angaphandle, umzimba ungangena esimweni se-ketosis ngaphandle kokuthi unamathele ngokuqinile ekudleni okune-carb ephansi, okunamafutha amaningi.Lokhu kunenzuzo ikakhulukazi kubasubathi kanye nabantu abafuna ukuthuthukisa ukusebenza kwabo ngokomzimba nokukhuthazela.
Kodwa-ke, kubalulekile ukuqaphela ukuthi nakuba i-ketone esters ingasiza abantu ukuthi bangene ku-ketosis ngokushesha, ayithathi indawo yokudla okunempilo, okunomsoco.Ukudla okungokwesiko kwe-ketogenic kukhonjiswe ukuthi kunezinzuzo eziningi zezempilo ezingaphezu kokuncipha kwesisindo, okuhlanganisa ukuzwela kwe-insulin okuthuthukisiwe, ukuvuvukala okuncishisiwe, nokucaca kwengqondo okuthuthukisiwe.Ngokunamathela ekudleni kwe-ketogenic, abantu ngabanye bangathola nezinguquko zesikhathi eside ku-metabolism ezingaba nemiphumela ehlala njalo empilweni yabo yonke kanye nokuphila kahle.
Isinqumo phakathi kwezidlo ze-ketogenic nezendabuko ze-ketogenic zehlela ekuthandweni komuntu siqu kanye nemigomo.Uma ufuna indlela yokuthola i-ketosis ngokushesha noma uthuthukise ukusebenza komzimba, i-ketone esters ingaba yinketho elungile kuwe.Kodwa-ke, uma ufuna indlela eqhubekayo, yesikhathi eside yokuthuthukisa impilo yakho nokuphila kahle, ukudla okungokwesiko kwe-ketogenic kungase kube ukukhetha okungcono.
Kubalulekile ukukhumbula ukuthi kungcono ukubonana nochwepheshe bezokunakekelwa kwempilo noma isazi sokudla ngaphambi kokwenza noma yiziphi izinguquko ezinkulu ekudleni.Banganikeza izincomo ezenziwe zaba ngezakho ngokusekelwe empilweni yakho siqu, imigomo, kanye nokudla okuncamelayo.
