Ukunyamezela kwi-Sugk Sugar (i-Lactose) Kubantwana

Ukunganyamezelani (ukungathobeli) kwe-lactose (ushukela wobisi) - enye yeentlobo zokunganyameli kokutya kubantwana. Ukuba umntwana akanalo i-enzyme ekhoyo kwindlela yamathumbu, okanye ukuba kukho i-enzyme (i-lactose) i-lactase (inqabile i-lactose), i-digestion (i-assimilation) yobisi ishukela (i-lactose) ayikho okanye ayifanelekanga.

Ukungabikho (okanye ukungabikho) kwe-lactase kukhokelela kwiimpawu ezinjengeentlungu zesisu, isifo sohudo, ukukhupha kunye nokubethelwa komntwana. Ukuba ukusetyenziswa kweebisi okanye iimveliso zobisi kunegalelo ekubonakaleni kweempawu, ke umntu unokuthi aphelise ukungabikho komonde kwi-lactose (ushukela wobisi).

I-Lactose (ushukela wobisi)

I-Lactose (ushukela wobisi) - eyona nto iphambili yeso ishukela ekwakheni ubisi. I-Lactose i-disaccharide kwaye iqulethwe ngamacwecwe alula (isishu elula) -glucose kunye ne-galactose (exhunywe ngebhuloji ye-oksijeni).

I-Lactose ifumaneka kubisi lwebele (kunye nakubisi lwezilwanyana ezithile, i-4-6%), eqinisekisa ukuphuhliswa komzimba kwiinyanga zokuqala zobomi.

I-Lactase (i-enzyme ephula ishukela yobisi)

I-enzyme (i-enzyme) i-lactase emzimbeni yenziwa kwiiseli ze-mucosa zesisu esincinci kwaye ihlukanisa i-lactose ibe yi-glucose ne-galactose.

Ukumisela (ukugaya) ubisi lomama, umntwana ufuna inani elikhulu lactase. Njengoko ubisi lukanina luphelelwa ukuba lube ngumthombo oyinhloko wesondlo kwintsana, inani le-lactase lenziwe liyehla. Nangona kunjalo, i-residual production of lactase ihlala kubantu abadala kwaye iqinisekisa ukufaniswa kwe-lactose ebisi kunye nemveliso yobisi.

Ukunganyamezelani kwe-lactose kaninzi?

Ukungathobeli i-lactose (ushukela wobisi) - into eqhelekileyo kwaye ayibonakali njengesifo, kodwa njengempawu yabantu abaninzi. Ubuncinane ama-50% wabemi abanokunyamezela kwe-lactose ukuya kumncinci nangaphezulu. Kwiintsana kunye nabantwana abancinci, ukunyamezela kwe-lactose kudlala indima yesibini (engaphantsi kwesiqhelo) kunobisi obunzima (iiprotheni zobisi).

Nangona kunjalo, ukunyanzeliswa kwe-lactose kubantwana kubaluleke kakhulu kunabantu abadala, kuba ubisi kunye nemveliso yobisi zibandakanya isabelo esikhulu kwisondlo sabantwana abancinci.
