Eminyakeni yamuva nje, izithasiselo ze-ketone ester ziye zathola ukuthandwa ngenxa yezinzuzo zazo ezingaba khona kwezempilo. Lezi zithasiselo ziyizinhlobo zokwenziwa zama-ketone, ezikhiqizwa yisibindi kusuka kuma-fatty acid ngezikhathi zokuzila ukudla noma ukudla ama-carbohydrate aphansi. Izithasiselo ze-ketone ester kukholakala ukuthi zinezinzuzo eziningi zezempilo, okuhlanganisa amandla akhuphukile, ukusebenza kwengqondo okuthuthukisiwe, kanye nokusebenza kahle kwezemidlalo okuthuthukisiwe. Okudingeka ukwazi ukuthi kubalulekile ukubonisana nochwepheshe wezempilo ngaphambi kokufaka noma yisiphi isithasiselo esisha ohlelweni lwakho lwansuku zonke.
Ama-ketone ayizinto eziphilayo ezikhiqizwa yisibindi lapho umzimba uphula amafutha ukuze uthole amandla. Avame ukuhlotshaniswa nokudla okunama-carbohydrate aphansi noma ukudla okune-ketogenic, lapho umzimba usesimweni se-ketosis, okusho ukuthi ushisa amafutha ukuze uthole amandla esikhundleni sama-carbohydrate.
Ama-ketone akhiqizwa uma umzimba ungenayo i-insulin eyanele yokusebenzisa i-glucose ukuze uthole amandla. Lokhu kungenzeka ngezikhathi zokuzila ukudla, ukuzivocavoca okunzima, noma ukudla okunama-carbohydrate aphansi. Uma umzimba ungenayo i-glucose eyanele ukuze uthole amandla, uqala ukuphula amafutha agciniwe bese uwaguqula abe ama-ketone. Lawa ma-ketone angasetshenziswa umzimba kanye nobuchopho njengomthombo wamandla ohlukile.
Kunezinhlobo ezintathu eziyinhloko zama-ketone akhiqizwa emzimbeni: i-acetoacetate, i-beta-hydroxybutyrate, kanye ne-acetone. Lawa ma-ketone angama-molecule ancibilika emanzini angasetshenziswa njengomthombo wamandla yimisipha, ubuchopho, nezinye izicubu. Eqinisweni, lapho umzimba use-ketosis, ubuchopho buyakwazi ukuthola amandla afinyelela ku-75% kuma-ketone.
Ngaphezu kwalokho, ama-ketone aboniswe ukuthi akhuthaza ukwehla kwesisindo ngokucindezela isifiso sokudla nokwandisa ukushiswa kwamafutha. Lesi ngesinye sezizathu ezenza ukuthi ukudla okunama-carbohydrate aphansi kanye ne-ketogenic kuvame ukusebenza kahle ekwehliseni isisindo. Ngokunciphisa inani lama-carbohydrate ekudleni kwakho nokwandisa ukudla kwakho amafutha anempilo namaprotheni, umzimba wakho uyakwazi ukungena esimweni se-ketosis bese uqala ukushisa amafutha ukuze uthole amandla, okuholela ekwehleni kwesisindo.
Ngakho-ke ayini ama-ketone esters? Ama-ketone esters ayizithako eziqukethe ama-ketone, okuyizinto eziphilayo ezikhiqizwa lapho umzimba uphula amafutha ukuze uthole amandla. Lawa ma-compound ayimikhiqizo yemvelo yezinqubo zomzimba futhi angakhiqizwa futhi ngokwenziwa. Ama-ketone esters ngokuvamile eza ngesimo soketshezi futhi angathathwa ngomlomo.
Ama-ketone esters angakusiza kanjani? Ama-ketone esters anikeza umzimba umthombo wamandla osheshayo. Uma umzimba use-ketosis, uthembele kuma-ketone esikhundleni se-glucose njengophethiloli. Lokhu kuzuzisa kakhulu abasubathi kanye nabantu abafuna ukuthuthukisa ukusebenza kwabo ngokomzimba.
Ngaphezu kokunikeza umthombo wamandla osheshayo, ezinye izifundo zibonisa ukuthi ama-ketone angawela isithiyo segazi nobuchopho futhi asetshenziswe njengomthombo wamafutha wobuchopho. Lokhu kuye kwavusa isithakazelo emiphumeleni engaba khona yokuthuthukisa ingqondo yama-ketone esters.
Ngaphezu kwalokho, ama-ketone ester angaba nezinzuzo ezingaba khona kubantu abadla ukudla okune-ketogenic. Ukudla okune-ketogenic kuwukudla okunamafutha amaningi, okune-carbohydrate ephansi okwenzelwe ukukhuthaza ukukhiqizwa kwama-ketone emzimbeni. Ngokudla ama-ketone ester, abantu abadla ukudla okune-ketogenic bangakwazi ukwandisa amazinga e-ketone, okungaholela ekushiseni amafutha amaningi kanye nokwehlisa isisindo.
Okokuqala, kubalulekile ukuqonda ukuthi ayini ama-ketone ester. Ama-ketone ester ayizithako zokudla ezikhulisa amazinga e-ketone egazini. Ngesikhathi sokudla okuncane, ukuvinjelwa kwama-carbohydrate, noma ukuzikhandla ngokomzimba isikhathi eside, isibindi sikhiqiza ama-ketone avela kuma-fatty acid. Uma umzimba ukwi-ketosis, ushintsha ekusebenziseni i-glucose njengomthombo wawo oyinhloko wamandla uye ekusebenziseni ama-ketone. Lesi simo se-metabolic sihlotshaniswa nezinzuzo eziningi zezempilo, okuhlanganisa nokwehlisa isisindo.
Izifundo eziningana ziphakamisa ukuthi ama-ketone ester angasiza ekunciphiseni isisindo. Ucwaningo olushicilelwe kumagazini i-Obesity luthole ukuthi abahlanganyeli abadle izithasiselo ze-ketone ester babhekene nokwehla kwesifiso sokudla, okwaholela ekunciphiseni ukudla. Olunye ucwaningo ku-Journal of Physiology lubonise ukuthi ama-ketone ester angakhuphula izinga lomzimba, okuholela ekushisweni kwamakhalori amaningi usuku lonke. Ngaphezu kwalokho, ama-ketone ester aboniswe ukuthi athuthukisa ukusebenza kokuzivocavoca, okungasiza kakhulu ekunciphiseni isisindo.
Kodwa kubalulekile ukuqaphela ukuthi ama-ketone ester awayona ikhambi elimangalisayo lokwehlisa isisindo. Nakuba engase abe namandla okusekela imizamo yokwehlisa isisindo, awathathi indawo yokudla okunempilo kanye nomsebenzi womzimba ojwayelekile.
Eminyakeni yamuva nje, i-ketosis ithole ukuthandwa njengendlela yokuthuthukisa ukusebenza kwezemidlalo, ukuthuthukisa ukucaca kwengqondo, nokusiza ukwehlisa isisindo. Abantu abaningi baphendukele kuma-ketone angaphandle kanye nama-ketone esters njengendlela yokufeza i-ketosis futhi bathole izinzuzo zayo ezingaba khona. Kodwa-ke, abantu bavame ukudideka ngomehluko phakathi kwalezi zithako ezimbili.
Ama-ketone angaphandle empeleni angama-ketone adliwa emithonjeni yangaphandle, njengezithasiselo. Angavela njengosawoti we-ketone, ama-ketone esters, kanye nama-triglycerides aphakathi nendawo (i-MCT). Lezi zithasiselo zenzelwe ukwandisa amazinga e-ketone egazini futhi zinikeze umzimba umthombo ohlukile wamafutha. Ama-ketone esters, ngakolunye uhlangothi, uhlobo oluthile lwe-ketone engaphandle ekhiqizwa ngamakhemikhali, ngokuvamile ngesimo soketshezi.
Omunye wemehluko omkhulu phakathi kwama-ketone ester namanye ama-ketone angaphandle ukuthi atholakala kalula kangakanani nokuthi akhuphula ngokushesha kangakanani amazinga e-ketone egazini. Ama-ketone ester aziwa ngokukhulisa amazinga e-ketone egazini ngokushesha ngemizuzu embalwa, okwenza kube ukukhetha okuthandwayo kwabadlali kanye nabantu abafuna ukukhulisa ama-ketone ngokushesha. Ngokuphambene nalokho, amanye ama-ketone angaphandle, njengosawoti we-ketone, angathatha isikhathi eside ukukhulisa amazinga e-ketone egazini.
Omunye umehluko obalulekile ukunambitheka kanye nokugayeka kwama-ketone ester uma kuqhathaniswa namanye ama-ketone angaphandle. Ama-ketone ester avame ukuba nokunambitheka okunamandla nokungathandeki ngenxa yokwakheka kwawo kwamakhemikhali futhi kungaba nzima kwabanye abantu ukuwadla. Ngakolunye uhlangothi, usawoti we-ketone kanye nama-glyceride aphakathi nendawo ngokuvamile anambitheka kakhudlwana futhi kulula ukuwafaka ohlelweni lwakho lwansuku zonke.
Ngokuphathelene nezindleko, ama-ketone ester ngokuvamile abiza kakhulu kunezinye ama-ketone angaphandle. Ukwenziwa kwama-ketone ester kuyinkimbinkimbi futhi kuyabiza, okubonakala ngentengo yawo. Usawoti we-ketone kanye nama-glycerides e-medium chain (ama-MCT), ngakolunye uhlangothi, ngokuvamile ashibhile futhi amukeleka kakhulu kubathengi. Ucwaningo olwengeziwe luphakamisa ukuthi ama-ketone ester angaba nemiphumela ehlukile yokuthuthukisa umzimba kanye nokusebenza, ikakhulukazi kubadlali kanye nabantu abafuna ukuthuthukisa ukusebenza komzimba.
Okokuqala nokubaluleke kakhulu, kubalulekile ukuqonda ukuthi ayini ama-ketone angaphandle nokuthi ahluke kanjani kuma-ketone akhiqizwa ngumzimba ngesikhathi se-ketosis. Ama-ketone angaphandle ayimizimba ye-ketone ethathwa njengezithasiselo, ngokuvamile ngefomu lempuphu noma lesiphuzo. Lawa ma-ketone angatholakala emithonjeni efana nosawoti we-beta-hydroxybutyrate (BHB) noma ama-ester, angakhuphula amazinga e-ketone egazini futhi abangele isimo se-ketosis ngisho noma kungekho mkhawulo oqinile wama-carbohydrate.
1.Thuthukisa ukusebenza ngokomzimba nangokwengqondo. Izifundo zibonisa ukuthi ama-ketone angumthombo wamandla ohlukile wobuchopho nemisipha, okwandisa ukukhuthazela, okuthuthukisa ukusebenza kwengqondo, kanye nokunciphisa umbono womzamo ngesikhathi sokuzivocavoca. Ngokunikeza umthombo wamandla olungele, izithasiselo ze-ketone zangaphandle zingasiza abathandi bokuqina komzimba ukuba badlule imikhawulo yemizimba yabo futhi bafinyelele ukusebenza okuphezulu.
2.Kusiza ekulawuleni isisindo kanye nempilo ye-metabolic. Ngokukhuthaza ukushisa amafutha nokunciphisa isifiso sokudla, ama-ketone angasiza abantu abafuna ukwehlisa isisindo noma ukuthuthukisa ukwakheka komzimba. Ngaphezu kwalokho, ama-ketone aboniswe ukuthi anomthelela omuhle ekuzweleni kwe-insulin kanye nokulawulwa koshukela egazini, okungazuzisa abantu abanezifo ze-metabolic ezifana nokukhuluphala ngokweqile noma isifo sikashukela sohlobo 2. Ukufaka izithasiselo ze-ketone zangaphandle ekudleni okuphelele kanye nokuzivocavoca umzimba kungasiza ekwenzeni ngcono ukusebenza kwe-metabolic futhi kukhuthaze impilo iyonke.
3.Khuthaza ukuguquka kwe-ketosis. Kulabo abasanda kuqala ukudla okune-ketogenic noma labo abaye baphambuka okwesikhashana ohlelweni lokudla olune-carb ephansi, ama-ketone angaphandle anganikeza indlela esheshayo nephumelelayo yokubuyela ku-ketosis. Lokhu kusiza kakhulu ekunciphiseni ukungakhululeki kanye nezimpawu "ze-keto flu" ezivame ukwenzeka ngezigaba zokuqala zokuvinjelwa kwama-carbohydrate. Ngokusebenzisa amasu okudla okune-ketone angaphandle, abantu banganciphisa izinselele zokushintshela esimweni se-ketogenic futhi bavune izinzuzo ze-ketosis ngokushesha.
Kubalulekile ukuqaphela ukuthi nakuba izithako ze-ketone zangaphandle zinikeza izinzuzo eziningi ezingaba khona, aziyona ikhambi elimangalisayo futhi kufanele zisetshenziswe kanye nokudla okulinganiselayo kanye nendlela yokuphila enempilo.
