Okuqukethwe
Ubisi nemikhiqizo yobisi sijwayele kusukela ebuntwaneni. Ubisi olunomsoco olucebile ngamavithamini nama-microelements lubalulekile ekukhuleni nasekuthuthukisweni okujwayelekile komzimba womuntu. Lo mkhiqizo ubaluleke kakhulu eminyakeni yokuqala yokuphila.
Kubantu abaningi, ukusetshenziswa kobisi kuhlala kuyisisekelo esiyisisekelo sokudla ezimpilweni zabo zonke: bayaluphuza, balingeze kuzo zonke izinhlobo zezitsha, bese belubilisa. Phakathi kwezinto eziningi ezizuzisayo zobisi, i-lactose idlala indima ebalulekile, noma ushukela wobisi, njengoba kubizwa nangokuthi.
Ukudla okunothile kwe-Lactose
Inani elicacisiwe (g) ku-100 g womkhiqizo
Izici ezijwayelekile ze-lactose
I-Lactose iyi-disaccharide eyenziwe ngama-molecule e-glucose nama-galactose angaphansi kwesigaba sama-carbohydrate. Ifomula yamakhemikhali ye-lactose imi kanje: C12H22O11, ekhombisa ubukhona bekhabhoni, i-hydrogen ne-oxygen kuyo ngamanani athile.
Mayelana nobumnandi, ushukela wobisi uphansi kune-sucrose. Itholakala obisini lwezilwane ezincelisayo nabantu. Uma sithatha izinga lobumnandi be-sucrose njenge-100%, iphesenti lobumnandi be-lactose lingu-16%.
I-Lactose inikeza umzimba amandla. Ingumthombo ophelele we-glucose - umphakeli omkhulu wamandla, kanye ne-galactose, edingekayo ekusebenzeni okujwayelekile kwesistimu yezinzwa.
Imfuneko yansuku zonke ye-lactose
Le nkomba ibalwa kucatshangelwa isidingo somzimba se-glucose. Ngokwesilinganiso, umuntu udinga ama-gramu ayi-120 kashukela ngosuku. Inani le-lactose kubantu abadala licishe libe yi-1/3 yaleli volumu. Ebuntwaneni, ngenkathi ubisi kungukudla okuyinhloko kwengane, zonke izingxenye eziyinhloko zokudla, kufaka phakathi i-lactose, zitholakala ngqo obisini.
Isidingo se-lactose siyanda:
- Ebuntwaneni, lapho ubisi luwumthombo oyinhloko wokudla namandla emntwaneni.
- Ngomsebenzi ophakeme womzimba kanye nemidlalo, ngoba i-lactose iyinto ebaluleke kakhulu yokudla okunempilo.
- Ukusebenza kwengqondo okusebenzayo kuholela ekwandeni kwesidingo somzimba sama-carbohydrate agaya kalula, afaka i-lactose.
Isidingo se-lactose siyancipha:
- Kubantu abaningi abaneminyaka yobudala (umsebenzi we-enzyme lactase uyancipha).
- Ngezifo zamathumbu, lapho ukugaya kwe-lactose kungasebenzi kahle.
Kulokhu, kunconywa ukunciphisa ukusetshenziswa kobisi nemikhiqizo yobisi.
Ukugaya i-lactose
Njengoba kushiwo ngenhla, ukuze kufakwe ushukela wobisi ngokugcwele emzimbeni, inani elanele le-enzyme lactase kufanele libe khona. Imvamisa ezinganeni ezisencane, kwanele le enzyme emathunjini ukugaya ubisi oluningi. Kamuva, kubantu abaningi, inani le-lactase liyancipha. Lokhu kwenza ukufana noshukela wobisi kube nzima. Emzimbeni womuntu, i-lactose yehlela kuma-monosaccharides ama-2 - i-glucose ne-galactose.
Izimpawu zokuntuleka kwe-lactase zifaka phakathi ukungasebenzi kahle kwamathumbu ahlukahlukene, kufaka phakathi ukuqumba, ukuduma esiswini, ukugaya ukudla, kanye nokuphikisana okwehlukile kokungezwani komzimba.
Izakhiwo eziwusizo ze-lactose nomphumela wayo emzimbeni
Ngaphezu kwamandla ubisi ongasinikeza umzimba, i-lactose inenye inzuzo ebalulekile. Iyasiza ekwenzeni umsebenzi wamathumbu ujwayelekile, inciphisa ukuthuthukiswa kwamagciwane, isiza ukuthuthukisa i-microflora yendlela yamathumbu, ngenxa yokwanda kwe-lactobacilli.
I-lactose equkethwe ubisi lomuntu ibhekwa njengebaluleke kakhulu. Ama-carbohydrate aqukethe i-nitrogen, atholakala kulo lolu bisi, akhuthaza ukukhula okusheshayo kwamakholoni e-lactobacilli, avikela umzimba kuzo zonke izinhlobo zesikhunta nezinambuzane. Ngaphezu kwalokho, i-lactose ivimbela ukubola kwamazinyo.
Ukusebenzisana nezinto ezibalulekile
Ixhumana ne-calcium, i-iron ne-magnesium, ikhuthaza ukumuncwa kwayo. Kubantu abanesifo samathumbu nokuntuleka kwenani elanele le-enzyme lactase, ushukela wobisi ungadala ukugcinwa kwamanzi emzimbeni.
Izimpawu zokuntuleka kwe-lactose emzimbeni
Imvamisa, izingane ezincane zihlushwa yilokhu. Kubantu abadala, zazingekho izimpawu ezisobala zokushoda kwe-lactose. Ngokushoda kwe-lactose, ubuthongo, ukozela nokungazinzi kohlelo lwezinzwa kuyabonakala
Izimpawu ze-lactose eyeqile emzimbeni:
- izimpawu zobuthi obujwayelekile bomzimba;
- ukungezwani komzimba;
- ukuqunjelwa;
- indle okuxekethile noma ukuqunjelwa.
Izici ezithinta okuqukethwe kwe-lactose yomzimba
Ukusetshenziswa njalo kwemikhiqizo equkethe i-lactose kuholela eqinisweni lokuthi amagciwane anenzuzo ahlala emathunjini athola konke akudingayo ukuze abe khona kanye nokugcwaliseka kwemisebenzi yawo.
Lapho amakoloni amaningi ehlala emzimbeni, ayanda amasosha omzimba wawo. Ngakho-ke, ukuze kugcinwe izinga eliphezulu lokuzivikela komzimba, umuntu kufanele agcwalise inani le-lactose, alithole emikhiqizweni yobisi.
I-Lactose ngobuhle nempilo
I-Lactobacilli, ekhula ngenxa yokuvikelwa kwe-enzyme lactase, iqinisa amasosha omzimba, yenze umuntu abe namandla, okuthinta ngokwemvelo ukubukeka. Ukusebenza okujwayelekile kwamathumbu kusiza ukuhlanza isikhumba, kuphulukisa indawo yesitho sangasese sowesifazane, kuqinisa uhlelo lwezinzwa. Ngokwemvelo, lo mphumela ubonwa kuphela ngokufakwa okugcwele koshukela wobisi emzimbeni.
Ngaphezu kwalokho, ukudla ukudla okuqukethe i-lactose kungasiza ekwehliseni isidingo soshukela ocwengekile, okubalulekile ekugcineni ubumhlophe bamazinyo emvelo nokumamatheka okukhazimulayo.
Siqoqe amaphuzu abaluleke kakhulu nge-lactose kulo mfanekiso futhi sizojabula uma wabelana ngesithombe kwinethiwekhi yokuxhumana noma kubhulogi, ngesixhumanisi saleli khasi:
