Okokuqala, masiqale siqonde ukuba yintoni i-ketone esters. I-Ketone esters yi-compounds ephuma kwimizimba ye-ketone, eveliswa sisibindi ngexesha lokuzila ukutya okanye i-carbohydrate ephantsi. Ezi khompawundi zinokusetyenziswa njengenye indawo yamafutha omzimba, ngakumbi ngamaxesha okwanda kwemfuno yamandla, njengaxa umthambo. Xa umzimba ukwi-ketosis, usebenzisa amafutha kumandla ngokufanelekileyo, ngaloo ndlela uphucula ukunyamezela nokunciphisa ukuthembela kwiivenkile ze-glycogen.
Okokuqala, makhe sichaze igama elithi "ketone ester." I-Ketones zikhompawundi eziphilayo eziveliswa sisibindi xa umzimba ukwimo ye-ketosis, eyenzeka xa umzimba utshisa amanqatha endaweni yeecarbohydrates zokubasa. I-Ketone esters, ngakolunye uhlangothi, i-synthetic compounds efana nemiphumo ye-ketosis, inika umzimba umthombo othe ngqo wamandla ngendlela yeetoni.
Ke, yintoni eyenza i-ketone esters ibe namandla kangaka? Enye yeenzuzo eziphambili ze-ketone esters kukukwazi ukunyusa ngokukhawuleza amanqanaba e-ketone yegazi, ukubonelela umzimba ngokukhawuleza kunye nomthombo wamandla osebenzayo. Oku kunenzuzo ngokukhethekileyo kubadlali kunye nabantu abafuna ukuphucula ukusebenza kwabo ngokomzimba, njengoko ii-ketones zingasetyenziselwa ukutshisa okucocekileyo kwimisipha kunye nengqondo, ngaloo ndlela ukwandisa ukunyamezela, ukunciphisa ukukhathala, nokuphucula ukubuyiswa. Ukongeza kwimiphumo yabo yokuphucula ukusebenza, i-ketone esters ibonakaliswe ukuba ineempawu ze-neuroprotective.
Ukongezelela, i-ketone esters ifundwe ngendima yabo enokubakho kwimpilo ye-metabolic, ngakumbi ekulawuleni ukutyeba kunye nesifo sikashukela. Ngokukhuthaza amandla omzimba okutshisa ngokufanelekileyo amanqatha kumafutha, i-ketone esters inokunceda ukuphucula ubuntununtunu be-insulin, ukulawula amanqanaba eswekile yegazi kunye nokukhuthaza ukwehla kobunzima.
Okokuqala, siqala ngee-esters. I-Esters ziikhompawundi eziphilayo ezenziwe xa ii-alcohols zisabela nge-carboxylic acid. Le ndlela yokusabela iphumela ekubunjweni kwemolekyuli ene-carbon-oxygen bond kabini (C = O) kunye ne-oksijini enye bond kunye nenye athom yekhabhoni. I-Esters zaziwa ngokumnandi, ivumba lazo elineziqhamo kwaye zihlala zisetyenziswa ekwenzeni iziqholo kunye neziqholo.
I-Ketones, kwelinye icala, zi-organic compounds eziqulethe iqela le-carbonyl (C=O) elidityaniswe kwii-athomu ezimbini ze-carbon. Ngokungafaniyo nee-esters, ii-ketones azinayo i-athomu ye-hydrogen edityaniswe kwi-carbonyl carbon. I-Ketones ifumaneka ngokuqhelekileyo kwindalo kwaye iphinda isetyenziswe kwiintlobo ezahlukeneyo zoshishino kunye nezorhwebo.
Omnye umehluko omkhulu phakathi kwe-esters kunye ne-ketones yinkqubo yabo yeekhemikhali kunye namaqela asebenzayo. Nangona zombini iikhompawundi zineqela le-carbonyl, indlela iqela le-carbonyl elidibanisa ngayo kwezinye ii-athom izenza zahluke enye kwenye. Kwi-esters, iqela le-carbonyl liboshwe kwi-athomu ye-oxygen enye kunye ne-athomu ye-carbon, ngelixa i-ketones, iqela le-carbonyl liboshwe kwii-athomu ezimbini ze-carbon.
Omnye umehluko obalulekileyo phakathi kwe-esters kunye ne-ketones kukusebenza kwakhona kunye neempawu zeekhemikhali. I-Esters iyaziwa ngevumba layo elimnandi kwaye isetyenziswa ngokuqhelekileyo njenge-condiments kunye neziqholo. Kwakhona banamanqaku aphantsi abilayo xa kuthelekiswa neetoni. I-Ketones, ngakolunye uhlangothi, ineqondo eliphezulu lokubilisa kwaye lisebenza ngakumbi ngenxa yobukho beqela le-carbonyl eliboshwe kwii-athomu ezimbini ze-carbon.
Ngokubhekiselele ekusebenziseni kwabo, ii-esters kunye neeketone zinezicelo ezahlukeneyo. I-Esters isetyenziswa ngokuqhelekileyo ekuveliseni iziqholo, iziqholo kunye nezithambiso, ngelixa ii-ketones zisetyenziselwa i-solvents, i-pharmaceuticals kunye neenkqubo zoshishino. Ukuqonda iimpawu ezizodwa kunye nokusebenza kwakhona kwezi khompawundi kubalulekile kwizicelo zazo ezahlukeneyo.
I-Autophagy yinkqubo yeselula apho iiseli zisusa i-organelles ezonakalisiweyo kunye neeprotheni ukugcina impilo. Kukholelwa ukuba ukuvuselela i-autophagy kunokuba noluhlu lweenzuzo zempilo ezinokubakho, ezifana nokwandisa ixesha lokuphila, ukunciphisa umngcipheko wezifo ezithile, kunye nokuxhasa ukusebenza kweselula ngokubanzi. I-Ketones, kwelinye icala, ziyi-compounds eziveliswayo xa umzimba udibanisa amanqatha ukuze ube namandla xa kungekho carbohydrates eyaneleyo. Ziye zadityaniswa kwiintlobo ngeentlobo zeenzuzo zempilo, kubandakanywa ukucaca okuphuculweyo kwengqondo, ukwehla kobunzima, kunye nempilo ye-metabolic.
Uphando lubonisa ukuba ii-ketones zinokuba nendima ekukhuthazeni i-autophagy. Uphononongo olupapashwe kwiphephancwadi lufumene ukuba i-ketones, ngokukodwa i-beta-hydroxybutyrate (BHB), inokwenza ngokuthe ngqo iindlela kwiiseli ezinoxanduva lokuqalisa nokulawula i-autophagy. Oku kuphakamisa ukuba amanqanaba e-ketone aphakanyisiweyo abangelwa kukutya kwe-ketogenic okanye ixesha lokuzila ukutya kunokuxhasa inkqubo yendalo ye-autophagy yomzimba.
Ukongezelela, ii-ketones zibonakaliswe ukuba zichaphazela ukubonakaliswa kweemfuza ezithile kunye neeprotheni ezibandakanyekayo kwi-autophagy. Kwesinye isifundo, abaphandi bafumanisa ukuba i-BHB ilawula ukubonakaliswa kwezakhi zofuzo ezinxulumene ne-autophagy kwiiseli ze-nerve, ezibonisa ukuba zingadlala indima ekuphuculeni le nkqubo yeselula.
Ngaphezu koko, ii-ketones zafunyaniswa zinezixhobo ezichasayo kunye ne-antioxidant, zombini ezo zihambelana ngokusondeleyo nenkqubo ye-autophagy. Ukuvuvukala okungapheliyo kunye noxinzelelo lwe-oxidative yonakalisa i-autophagy, ekhokelela ekuqokeleleni kwamacandelo eeselula ezonakalisiweyo kwaye inokuba negalelo ekuphuhliseni izifo ezahlukeneyo. Ngokunciphisa ukuvuvukala kunye noxinzelelo lwe-oxidative, ii-ketones zixhasa amandla omzimba okusebenza ngokufanelekileyo kwe-autophagy kunye nokugcina impilo yeselula.
Nangona kunjalo, kubalulekile ukuba uqaphele ukuba ngelixa i-ketones ingaba namandla okunyusa i-autophagy, indawo eveliswa kuyo ibalulekile. Ngokomzekelo, amanqanaba e-ketone aphakanyisiweyo ngokusebenzisa i-ketosis yezondlo, ukuzila ukutya, okanye ukuxhaswa kwe-ketone exogenous kunokuxhasa i-autophagy, kanti i-ketones eveliswayo ngenxa yesifo sikashukela esingalawulwayo (isifo seswekile ketoacidosis) ayinayo izibonelelo zempilo ezifanayo ezikhuthaza iziphumo kwaye zinokuba yingozi.
I-Ketone esters i-compounds equkethe iqela le-ketone, iqela elisebenzayo eliqukethe iqela le-carbonyl (C = O) elidibaniswe kwii-athomu ezimbini ze-carbon. Xa zifakwe, ezi zixhobo ziguqulwa ngokukhawuleza zibe yi-ketones, iimolekyuli ezibalulekileyo ezisebenza njengomthombo wamandla ongomnye womzimba kunye nengqondo, ngakumbi ngexesha lokusetyenziswa kwe-carbohydrate ephantsi. Oku kwenza ukuba i-ketone esters ibe lukhetho oludumileyo kubantu abalandela ukutya kwe-ketogenic okanye ukujonga ukuphucula ukusebenza ngokomzimba nangokwengqondo.
