Kev xav, amylose cov yuav tsum yooj yim zom dua vim tias nws tsis xav tau isomaltase, thiab tsis muaj qhov cuam tshuam tsis zoo los ntawm cov ceg ntoo. Txawm li cas los xij, amylose cov tuaj yeem tsim cov qauv kev sib txuam ntawm lub cev, uas txwv kev zom zaub mov. Yog li ntawd, amylopectin yog qhov tseeb zom zoo tshaj amylose cov.
Dhau li, uas yog cov kua amylose lossis amylopectin ntau dua?
Vim tias txoj kab ntev ntev ntawm amylose mas nkag tau yooj yim dua amylopectin (uas muaj luv, muaj cov saw loj heev), siab- amylose cov yog starch ntau dua tiv taus kev zom. Tsis zoo li amylopectin , amylose cov tsis yog soluble hauv dej txias. Qee qhov chaw hais tias 1.7 g/L thaum lwm tus hais tias nws yog dej tsis haum.
Qhov thib ob, peb puas tuaj yeem zom amylopectin? Thaum lub zog xav tau rau kev ua haujlwm ntawm tes, cov nroj tsuag hydrolyzes cov hmoov txhuv nplej siab, tso cov piam thaj hauv qab. Tib neeg thiab lwm yam tsiaj uas noj zaub mov cog kuj tseem siv amylase, ib qho enzyme uas pab ua kom tawg amylopectin . Amylopectin yog cov ceg ntoo loj heev, tau tsim los ntawm 2, 000 txog 200, 000 units piam thaj.
Zoo ib yam tuaj yeem nug, qhov sib txawv ntawm amylose thiab amylopectin yog dab tsi?
Amylose thiab amylopectin yog ob hom polysaccharides uas tuaj yeem pom hauv cov hmoov txhuv nplej siab. Lawv muaj ob yam qauv thiab tshuaj sib txawv zoo li zoo sib xws . Lub ntsiab qhov sib txawv ntawm amylose thiab amylopectin yog li amylose cov yog cov saw hlau ncaj ncaj qhov twg amylopectin yog branched saw polymer.
Dab tsi starches siab hauv amylose?
High-amylose pob kws muaj 70 feem pua amylose, tsis tu ncua pob kws muaj li ntawm 28 feem pua thiab sago thiab nplej muaj li 26 feem pua amylose. Arrowroot muaj li ntawm 21 feem pua amylose, qos yaj ywm yog kwv yees li 20 feem pua amylose, qos yaj ywm qab zib muaj 18 feem pua amylose thiab qos yaj ywm yog li 17 feem pua amylose.

Dab tsi yog qhov sib txawv ntawm squamous yooj yim thiab yooj yim cuboidal thiab columnar yooj yim?
Piv txwv li, yooj yim squamous epithelial cov ntaub so ntswg piav qhia ib txheej ntawm cov cell uas tiaj thiab nplai zoo li cov duab. Cuboidal epithelium muaj cov cell uas nws qhov siab thiab dav yog kwv yees tib yam. Columnar epithelium muaj cov cell siab dua li lawv dav
Yog yogurt yooj yim dua zom dua mis?
Cov ntsiab lus: Cov neeg tsis kam txais Lactose feem ntau pom cov kua mis nyeem qaub yooj yim dua zom dua mis. Cov kua mis nyeem qaub zoo tshaj plaws rau cov neeg uas tsis kam lees lactose yog cov rog tag nrho, cov kua mis nyeem qaub uas muaj cov kab mob muaj sia nyob
Nws puas yooj yim dua kom muaj sia nyob hauv qhov kub lossis txias?
Mob khaub thuas xav tau calories ntau dua li cua sov, thiab zaub mov yuav tsis txaus. Thaum tshav kub kub xav tau dej ntau, tab sis tuaj yeem ua se rau kev ua haujlwm sab nraum zoov. Kuv xav tias thaum kawg cua sov yuav yooj yim dua, tab sis qhov txias tuaj yeem yooj yim dua yog tias muaj chaw nyob thiab khaub ncaws tsim nyog
Puas yog amylose lossis amylopectin muaj qhov glycemic index siab dua?
Starch molecules yog tsim los ntawm ob hom carbohydrates, amylose thiab amylopectin. Amylose yog ntev thiab tawm ncaj thaum amylopectin yog cov ceg ntoo heev. Amylopectin tau tawg sai thiab muaj qhov ntsuas glycemic siab dua, txhais tau tias nws tuaj yeem nce ntshav qab zib sai tom qab noj mov
Qhov twg cov hlau ntxiv yog qhov yooj yim tshaj plaws ntawm lub plab?
Ferric hlau: Cov hlau no yuav tsum tau tawg los ntawm lub cev kom dhau los ua cov khoom siv tau. Yog li ntawd, nws tsis yog yooj yim absorbed los yog raws li nquag pom zoo. Txawm li cas los xij, yog tias koj lub plab tsis tuaj yeem zam cov hlau ferrous, hom no yooj yim dua ntawm lub plab
