Glucose yog dab tsi? Txhua tus siv nws, tab sis ob peb tus tuaj yeem muab cov ntsiab lus. Qhov no yog ib yam khoom uas tib neeg lub cev xav tau. Tib neeg kev noj qab haus huv nyob ntawm kev noj qab haus huv raws sijhawm.
Carbohydrates, proteins thiab rog tuaj yeem muab lub zog rau lub cev. Tab sis cov piam thaj yog cov khoom uas yog thawj ntawm cov uas siv rau lub zog xav tau.
Definition
Glucose, tseem hu ua dextrose, yog cov hmoov dawb lossis tsis muaj xim uas tsis muaj ntxhiab thiab muaj qab zib. Glucose yog ib yam khoom uas tuaj yeem hu ua roj thoob ntiaj teb rau tib neeg lub cev. Tom qab tag nrho, feem ntau ntawm cov kev xav tau ntawm lub zog tsuas yog them rau ntawm nws cov nuj nqis. Nws yuav tsum muaj nyob rau hauv cov ntshav txhua lub sijhawm. Tab sis nws yuav tsum tau muab sau tseg tias nws tshaj, raws li zoo raws li nws deficiency, yog txaus ntshai. Thaum tshaib plab, lub cev noj cov khoom uas nws tsim los ntawm. Hauv qhov no, cov leeg nqaij protein hloov mus rau hauv qabzib. Qhov no tuaj yeem txaus ntshai heev.
Lub cev ntawm cov piam thaj
Glucose yog dab tsi? Raws li tau hais ua ntej, nws yog xim tsis muaj xim, qab zib crystalline khoom. Nws dissolves zoo heev hauv dej. Glucose muaj nyob rau hauv yuav luag tag nrho cov nroj tsuag kab mob: nyob rau hauv paj, keeb kwm, txiv hmab txiv ntoo thiab nplooj. Muaj ntau cov piam thaj hauv cov txiv hmab txiv ntoo thiab txiv hmab txiv ntoo, nrog rau cov kua txiv hmab txiv ntoo. Nws kuj muaj nyob rau hauv cov tsiaj muaj sia. Qhov feem ntawm cov tshuaj nyob rau hauv tib neeg cov ntshav yog kwv yees li ib feem kaum ntawm ib feem pua.
tshuaj muaj txiaj ntsig ntawm qabzib
Glucose yog dab tsi? Qhov no yog ib yam khoom ntawm polyhydric cawv. Nws cov qauv yog C6H12O6. Yog hais tias cov kua qab zib tau ntxiv rau cov dej nag uas tsis tshua muaj tooj liab hydroxide, yuav tau txais cov tshuaj xiav kaj. Yuav kom muaj ib daim duab tiav ntawm cov qauv ntawm cov khoom, nws yog ib qho tsim nyog yuav tsum paub yuav ua li cas cov piam thaj molecule tsim. Txij li thaum cov pa oxygen atoms yog cov pab pawg ua haujlwm, cov pa roj carbon atoms uas tsim cov pob txha ntawm cov molecule tau txuas ncaj qha rau ib leeg.
Glucose kua muaj cov molecules nrog qhib saw ntawm atoms, nrog rau cov cyclic sawv daws yuav. Glucose yog dab tsi? Qhov no yog ib yam khoom uas muaj ob yam tshuaj. Nws tsim esters, oxidizes. Cov piam thaj hauv lub cev tuaj yeem tawg ua ob lub hlwb lactic acid thiab lub zog dawb. Cov txheej txheem no hu ua glycolysis. Cov piam thaj molecule muaj nyob rau hauv peb hom isomeric. Ib tug yog linear thiab ob tug yog cyclic.
Glucose thiab zaub mov
Glucose nkag mus rau tib neeg lub cevnrog rau cov carbohydrates. Tom qab nkag mus rau hauv cov hnyuv, lawv tau tawg, tig mus rau hauv cov piam thaj, uas tom qab ntawd nkag mus rau hauv cov hlab ntsha. Ib feem ntawm cov khoom siv yog siv rau lub zog xav tau ntawm lub cev, lwm qhov yog tso rau hauv daim ntawv ntawm cov roj reserves. Qee cov piam thaj khaws cia ua ib yam khoom hu ua glycogen. Tom qab kev zom zaub mov thiab kev tso tseg ntawm cov piam thaj nkag mus rau hauv cov ntshav los ntawm txoj hnyuv, cov txheej txheem rov qab hloov pauv ntawm glycogen thiab cov rog rau hauv cov piam thaj pib. Nyob rau hauv txoj kev no, tib neeg lub cev tswj hwm cov piam thaj hauv cov ntshav mus tas li. Feem ntau, cov txheej txheem ntawm kev hloov cov rog thiab cov proteins rau hauv qabzib thiab rov qab siv sijhawm ntev heev. Tab sis tib txheej txheem nrog piam thaj thiab glycogen tshwm sim sai dua. Nws yog vim li no tias glycogen yog lub ntsiab cia carbohydrate.
Hormones-regulators
Cov txheej txheem hloov cov piam thaj mus rau glycogen thiab rov ua dua yog tswj hwm los ntawm cov tshuaj hormones. Insulin txo qhov concentration ntawm cov piam thaj hauv tib neeg cov ntshav. Ua kom nws cov tshuaj hormones xws li adrenaline, glucagon, cortisol. Yog tias muaj kev ua txhaum cai tshwm sim hauv kev ua raws li cov kev cuam tshuam ntawm glycogen thiab qabzib, ib tus neeg mob hnyav yuav tshwm sim. Ib tug yog ntshav qab zib.
Yuav ntsuas ntshav qab zib li cas?
ntshav qabzib yog qhov ntsuas tseem ceeb siv los kuaj ntshav qab zib. Hauv venous thiab capillary cov ntshav qabzib sib txawv. Nws tuaj yeem hloov pauv vim kev tshaib plab lossis satiety ntawm tus neeg. Thaum ntsuas ntawm lub plab khoob (tsawg yim teev tom qab noj mov) hauvHauv cov ntshav venous, cov piam thaj yuav tsum yog los ntawm 3.3 mus rau 5.5 millimoles ib liter, thiab hauv cov ntshav capillary me ntsis ntxiv - los ntawm 4 mus rau 6.1 millimoles ib liter. Ob peb teev tom qab noj mov, qib ntawm cov tshuaj yuav tsum tsis txhob siab tshaj 7.8 millimoles ib liter. Qhov no siv rau ob leeg venous thiab capillary ntshav. Yog hais tias nyob rau hauv ib lub lis piam, thaum ntsuas ntawm lub plab khoob, cov piam thaj tsis poob qis dua 6.3 millimoles ib liter, koj yuav tsum sab laj nrog kws kho mob endocrinologist tam sim ntawd, nrog rau kev kuaj ntxiv.
ntshav qabzib ntau
Tus mob no hu ua hyperglycemia. Nws tshwm sim feem ntau hauv ntshav qab zib mellitus. Dab tsi tuaj yeem ua rau qib qabzib nce ntxiv? Qhov laj thawj yog:
- mob ntshav qab zib mellitus;
- kev nyuaj siab, muaj zog siab ntxhov siab;
- myocardial infarction;
- kab mob ntawm lub raum, pancreas thiab endocrine system;
- kev tawm dag zog.
Thaum muaj kev ntxhov siab, cov ntshav qabzib tuaj yeem nce. Qhov no yog vim lub fact tias tib neeg lub cev, teb rau xws li ib tug tshwm sim, pib secrete cov tshuaj hormones kev nyuaj siab. Thiab lawv tsuas yog nce qib ntawm cov piam thaj hauv cov ntshav. Hyperglycemia sib txawv hauv qhov hnyav ntawm me me mus rau nruab nrab mus rau coma thaum cov piam thaj ntau tshaj 55.5 millimoles ib liter.
ntshav qab zib qis
qhov tshwm sim no hu ua hypoglycemia. Qhov no yog ib qho mob uas qhov concentration ntawm cov tshuaj nyob rau hauv cov ntshav yog tsawg dua 3.3 millimoles ib liter. Dab tsi yogKev kho mob tshwm sim ntawm hypoglycemia? Cov no tuaj yeem yog: cov leeg tsis muaj zog, tawm hws hnyav, tsis meej pem, tsis muaj kev sib koom tes.
ntshav qabzib poob vim yog yam xws li:
- noj tsis txaus lossis tshaib plab;
- kab mob ntawm daim siab thiab pancreas;
- ua kom lub cev muaj zog;
- kab mob ntawm endocrine system;
noj tshuaj insulin ntau dhau.
Ib tug neeg uas muaj ntshav qabzib hnyav hnyav tuaj yeem nkag mus rau hauv qhov tsis nco qab hypoglycemic.
Glucose thiab tshuaj
Kev daws ntawm cov tshuaj no yog siv los kho ntau tus kab mob, nrog rau qhov tsis muaj qabzib. Lawv kuj dilute ib co tshuaj ua ntej txhaj rau hauv cov hlab ntsha.
Glucose yog ib yam khoom tsim nyog uas ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm tib neeg lub cev.
Daim ntawv thov
Glucose yog cov khoom noj muaj txiaj ntsig zoo. Starch, uas muaj nyob rau hauv cov zaub mov, nkag mus rau hauv lub digestive ib ntsuj av, hloov mus rau hauv qabzib. Los ntawm qhov ntawd nws kis thoob plaws lub cev. Txij li cov tshuaj no tau yooj yim nqus los ntawm lub cev, thiab tseem muab lub zog, cov piam thaj yog siv los ua kom muaj zog ntxiv.
Vim nws qab zib, nws kuj siv rau hauv cov khoom qab zib. Glucose yog qab zib uas yog ib feem ntawm molasses, caramel, marmalade, gingerbread. Feem ntau, tag nrho cov carbohydrates yooj yim, uas yog hu ua suab thaj, muab faib ua ob hom: qabzib, fructose. Thiab feem ntau ib yam khoom muaj ib tug sib tov ntawm lawv. Ib qho piv txwv yog cov suab thaj, uas ob yam khoom no sib npaug.
Nws tsim nyog nco ntsoov thiabKev noj ntau ntawm cov khoom qab zib ua rau tib neeg lub cev. Tom qab tag nrho, muaj cov kab mob xws li rog, caries, ntshav qab zib. Lub neej luv vim qhov no. Yog li ntawd, koj yuav tsum tau saib xyuas koj cov khoom noj kom zoo thiab noj tag nrho cov khoom tsim nyog nyob rau hauv ib txwm muaj. Ces kev noj qab nyob zoo yuav zoo.
