Iitumato ezihlelwe ngokwemfuza zinokubonelela ngomthombo omtsha wevithamin D

Iitumato zivelisa ngokwendaloivithamin Dprecursors.Ukuvala indlela ukuyiguqulela kwezinye iikhemikhali kunokukhokelela ekuqokeleleni kwangaphambili.
Izityalo ze-tomato ezilungelelaniswe ngofuzo ezivelisa i-vitamin D zangaphambili zinokubonelela ngomthombo ongenasilwanyana wezondlo eziphambili.

Kuqikelelwa ukuba i-1 yezigidigidi zabantu abafumani ngokwaneleyo i-vitamin D - imeko engakhokelela kwiintlobo zeengxaki zempilo, kubandakanywa ukuphazamiseka kwe-immune kunye ne-neurological.ivithamin Dkwiimveliso zezilwanyana ezifana namaqanda, inyama, kunye nobisi.
Xa i-tomato ehlelwe ngofuzo echazwe kwiZityalo zeNdalo ngoMeyi 23 ibonakaliswe ekukhanyeni kwe-ultraviolet kwilebhu, ezinye ii-precursors ezibizwa ngokuba yi-vitamin D3 zaguqulwa zaba yi-vitamin D3. Kodwa ezi zityalo azikaphuhliswa ukusetyenziswa kwezorhwebo, kwaye akwaziwa. baya kuziphatha njani xa bekhulele ngaphandle.
Nangona kunjalo, isazi ngebhayoloji yezityalo uJohnathan Napier woPhando lweRothamsted eHarpenden, eUK, lo ngumzekelo othembisayo nongaqhelekanga wokusebenzisa ukuhlela imizila yemfuza ukuphucula umgangatho wesondlo sezityalo. into oyiqondayo,” utshilo.

Ukuhlelwa kwemfuza yindlela evumela abaphandi ukuba benze utshintsho olujoliswe kuyo kwi-genome yezinto eziphilayo kwaye kuye kwanconywa njengendlela enokubakho yokuphuhlisa izityalo ezingcono.Ngelixa izityalo eziguqulwe ngokwemfuza ezenziwe ngokufaka imfuza kwi-genome yesityalo ngokuqhelekileyo kufuneka zihlolwe ngokubanzi ngabalawuli bakarhulumente, amazwe amaninzi ayilungelelanise inkqubo yezityalo zokuhlela i-genome-ngaphandle nje kokuba ukuhlelwa kulula kwaye uguquko oluyisiphumo lunokuba notshintsho lwendalo lwendalo .
Kodwa uNapier uthe kukho iindlela ezimbalwa zokusebenzisa olu hlobo lokuhlelwa kwemfuza ukuphucula isiqulatho sesondlo sezityalo.Nangona ukulungiswa kwemfuza kungasetyenziselwa ukuvala imizila yemfuza ngeendlela eziluncedo kubathengi-umzekelo, ngokususa iikhompawundi zezityalo ezinokusebenza. kubangela ukwaliwa nomzimba—kunzima kakhulu ukufumana uguqulo lwemfuza olukhokelela kwizakha mzimba ezintsha zemfuza.”Ukomeleza ngokwenene isondlo, kufuneka ubuye umva ucinge, ingaba siluncedo kangakanani esi sixhobo?”watsho uNapier.

Ngelixa ezinye izityalo ngokwemvelo zivelisa uhlobo lwevithamin D, ngokuqhelekileyo kamva luguqulwa lube yikhemikhali elawula ukukhula kwezityalo.Ukuthintela indlela yokuguqulwa kukhokelela ekuqokeleleni kwe-vitamin D precursors, kodwa kwakhona ekukhuleni kwezityalo. ukuba ufuna ukwenza izityalo ezivelisa isivuno esikhulu,” utsho uCathie Martin, isazi ngezityalo kwiJohn Innes Centre eNorwich, eUnited Kingdom.
Kodwa i-nightshades nayo ine-parallel biochemical pathway eguqula i-provitamin D3 ibe yi-confensive compounds.UMartin kunye noogxa bakhe basebenzise le nto kwizityalo zobunjineli ezivelisa i-vitamin D3: Bafumanisa ukuba ukuvala indlela ekhokelela ekuqokeleleniivithamin Dizandulela ngaphandle kokuphazamisa ukukhula kwezityalo kwilebhu.
UDominique Van Der Straeten, isazi sebhayoloji yezityalo kwiYunivesithi yaseGhent eBelgium, uthe abaphandi kufuneka ngoku bagqibe ukuba ukuthintela ukuveliswa kweekhompawundi zokhuselo xa kukhuliswe ngaphandle kwebhubhoratri kuchaphazela amandla etumata ukujamelana noxinzelelo lwendalo.
UMartin kunye noogxa bakhe baceba ukufunda oku kwaye sele befumene imvume yokukhulisa iitamatisi zabo ezihlelwe kwi-gene kwintsimi.Iqela lalifuna ukulinganisa umphumo we-UV yangaphandle ye-UV ekuguqulweni kwe-vitamin D3 kwi-vitamin D3 kumagqabi ezityalo kunye neziqhamo. .“E-UK, phantse ukuba itshabalele,” waqhula uMartin, ebhekisela kwimozulu yelizwe edume ngokuba nemvula. Wathi xa wayeqhagamshelana nomntu osebenza naye e-Itali embuza ukuba angakwazi kusini na ukwenza olu vavanyo ilanga lizele, waphendula ngelithi kuya kufuneka. malunga neminyaka emibini ukufumana imvume yokulawula.
Ukuba iitumato ziqhuba kakuhle kwizifundo zasemasimini, zinokugqiba ekubeni zizidibanise noluhlu olulinganiselweyo lwezityalo ezongeziweyo ezifumaneka kubathengi.Kodwa uNapier ulumkisa ngelithi indlela eya emarikeni inde kwaye izele ziingxaki ezibandakanya ubukrelekrele, iimfuno zolawulo kunye nemingeni yolungiselelo. Irayisi - inguqulelo yobunjineli yesityalo evelisa i-vitamin A precursor - ithathe amashumi eminyaka ukusuka kwiibhentshi zaselabhu ukuya kwiifama, phambi kokuba ivunywe ukulinywa kwezorhwebo ePhilippines kulo nyaka uphelileyo.
Ilebhu kaVan Der Straeten ikhulisa izityalo eziguqulwe ngokwemfuza ezivelisa amanqanaba aphezulu ezondlo ezahlukeneyo, kuquka ifolate, ivithamin A kunye nevithamin B2. Kodwa ukhawuleza aveze ukuba esi sityalo siqinisiweyo sinokujongana nokungondleki kuphela.” iindlela esinokunceda ngazo abantu, utshilo. ”Ngokucacileyo iyakuthatha amanyathelo ahlukeneyo. ”
