Cov kws tshawb fawb tau ua pov thawj tias sucrose muaj nyob hauv txhua cov nroj tsuag, thiab pom muaj ntau hauv cov neeg siv khoom xws li qab zib beet thiab cane. Hauv kev noj haus ntawm txhua tus neeg, lub luag haujlwm ntawm sucrose yog qhov loj txaus.

Sucrose yog ib qho disaccharide (tseem nyob rau hauv chav kawm ntawm oligosaccharides), uas, nyob rau hauv qhov kev txiav txim ntawm cov enzyme sucrose los yog nyob rau hauv qhov kev txiav txim ntawm ib tug acid, yog hydrolyzed rau hauv qabzib (tag nrho cov loj polysaccharides muaj nws) thiab fructose (txiv hmab txiv ntoo qab zib), ntau precisely, lub sucrose molecule muaj residues D -fructose thiab D-glucose. Cov khoom tseem ceeb thiab siv tau uas ua haujlwm los ntawm sucrose yog cov suab thaj zoo tib yam.

Hauv chemistry, sucrose molecule yog sau los ntawm cov qauv hauv qab no - C₁₂H₂₂O_{11thiab yog isomer.}

YHydrolysis ntawm sucrose

Sucrose yog qhov tseem ceeb tshaj plaws ntawm cov disaccharides. Raws li tuaj yeem pom los ntawm qhov sib npaug, hydrolysis ntawm sucrose ua rau tsim cov ntsiab lus xws li qabzib thiab fructose. Lawv cov qauv molecular yog tib yam, tab sis lawv cov qauv qauv sib txawv kiag li:

CH₂(OH) -(CHOH)_{4-SLEEP - qabzib.}

Lub cev muaj zog ntawm sucrose

1. Sucrose yog cov xim tsis muaj xim, qab zib hauv saj, uas yaj zoo hauv dej.
2. 160 ° C yog qhov kub thiab txias rau qhov melting ntawm sucrose.
3. Caramel yog amorphous pob tshab loj uas tsim thaum molten sucrose solidifies.

tshuaj lom neeg ntawm sucrose

1. Sucrose tsis yog aldehyde.
2. Sucrose yog qhov tseem ceeb tshaj plaws disaccharide.
3. Thaum cua sov nrog cov tshuaj ammonia, Ag₂O tsis muab qhov hu ua "silver mirror", thiab thaum rhuab nrog Cu(OH) 2 _{tsis tsim tooj liab oxide.}
4. Yog tias koj boil ib qho kev daws ntawm sucrose nrog 2-3 tee ntawm sulfuric lossis hydrochloric acid, thiab tom qab ntawd ua rau nws nrog cov alkali, tom qab ntawd ua kom sov cov txiaj ntsig daws nrog Cu (OH) 2, tom qab ntawd cov kua dej liab yuav tsim.

YComposition ntawm sucrose

Lub sucrose molecule, raws li koj paub, muaj cov seem ntawm fructose thiab qabzib, uas yog sib txuas zoo. Ntawm cov isomers uas muaj cov mis mos molecular C₁₂H₂₂O_{11,cov hauv qab no yog qhov txawv: m altose (m alt qab zib) thiab, tau kawg, lactose (mis qab zib).}

Qhov cuam tshuam ntawm sucrose ntawm tib neeg lub cev

Sucrose muab tib neeg lub cev nrog lub zog tsim nyog rau nws txoj haujlwm tag nrho. Nws kuj tseem txhim kho lub hlwb kev ua haujlwm ntawm tus neeg thiab txhawb kev tiv thaiv kev ua haujlwm ntawm nws lub siab los ntawm cov teebmeem ntawm cov tshuaj lom. Txhawb nqa lub neej txhawb nqa ntawm cov leeg nqaij striated thiab paj hlwb. Yog li ntawd, sucrose yog ib qho tseem ceeb tshaj plaws uas muaj nyob rau hauv yuav luag tag nrho cov tib neeg noj khoom.

Nrog tsis muaj sucrose hauv ib tus neeg, cov xwm txheej hauv qab no tau pom: kev nyuaj siab, chim siab, tsis txaus siab, tsis muaj zog, tsis muaj zog. Tus mob no tuaj yeem ua rau tsis zoo yog tias cov ntsiab lus sucrose hauv lub cev tsis zoo li qub raws sijhawm. Tshaj sucrose ua rau cov hauv qab no: caries, ntau dhau lawm, kab mob hauv lub cev, kab mob ntawm lub qhov ncauj, kev txhim kho candidiasis thiab khaus ntawm qhov chaw mos, muaj kev pheej hmoo ntawm kev mob ntshav qab zib..

Qhov kev xav tau ntawm sucrose nce ntxiv nyob rau hauv cov xwm txheej uas tib neeg lub hlwb tau dhau los ntawm kev ua haujlwm hnyav, thiab (lossis) thaum tib neeg lub cev raug cuam tshuam los ntawm cov tshuaj lom neeg hnyav. Kev xav tau ntawm sucrose yog txo qis yog tias tus neeg muaj ntshav qab zib lossis rog dhau.

Cov txiaj ntsig ntawm fructose thiab qabzib rautib neeg lub cev

Raws li nws tau tshwm sim ua ntej, vim qhov kev cuam tshuam ntawm "sucrose - dej", cov ntsiab lus xws li fructose thiab qabzib yog tsim. Xav txog cov yam ntxwv tseem ceeb ntawm cov khoom no thiab cov ntsiab lus no cuam tshuam rau tib neeg lub neej li cas.

Fructose, ib hom piam thaj molecule pom hauv cov txiv hmab txiv ntoo tshiab, muab lawv cov qab zib. Raws li qhov tshwm sim, ntau tus ntseeg tias fructose yog qhov zoo tshaj plaws. yog ib tug natural tivthaiv. Tsis tas li ntawd, fructose muaj qhov cuam tshuam tsawg ntawm cov piam thaj (vim tias nws muaj qhov ntsuas glycemic qis).

Fructose nws tus kheej yog qab zib heev, txawm li cas los xij, cov txiv hmab txiv ntoo paub rau txiv neej muaj tsawg tsawg ntawm nws. Raws li qhov tshwm sim ntawm qhov no, ib qho me me ntawm cov piam thaj nkag mus rau hauv peb lub cev, uas tau ua tiav sai heev. Txawm li cas los xij, koj yuav tsum tsis txhob qhia ntau ntau ntawm fructose rau hauv lub cev, vim tias. Kev siv nws ntau dhau tuaj yeem ua rau muaj qhov tshwm sim xws li kev rog rog, cirrhosis (scarring ntawm daim siab), gout thiab kab mob plawv (nce qib ntawm uric acid), fatty siab thiab, ib txwm, kev laus ntxov ntawm daim tawv nqaij, ua rau wrinkles.

Raws li kev tshawb fawb, cov kws tshawb fawb tau xaus lus tias fructose, tsis zoo li cov piam thaj, khaws cov cim ntawm kev laus sai dua. Peb tuaj yeem hais dab tsi txog kev hloov pauv fructose.

Raws li cov khoom siv yav dhau los, peb tuaj yeem txiav txim siab tias noj cov txiv hmab txiv ntoo tsim nyog yog qhov zoo rau tib neeg noj qab haus huv, vim tias lawv muaj qhov tsawg kawg nkaus ntawm fructose. TABSISntawm no concentrated fructose yuav tsum tau zam vim nws tuaj yeem ua rau muaj mob tiag.

Glucose - zoo li fructose, yog hom qab zib, thiab yog hom carbohydrate - feem ntau hom. Glucose yog tau los ntawm cov hmoov txhuv nplej siab, nws nce cov ntshav qab zib sai sai thiab muab lub zog rau peb lub cev rau lub sijhawm ntev.

Yog tias koj pheej noj cov zaub mov uas ua tiav, lossis cov hmoov txhuv nplej siab yooj yim, uas suav nrog mov dawb lossis hmoov nplej dawb, qhov no yuav ua rau cov ntshav qab zib nce ntxiv. Thiab qhov tshwm sim ntawm qhov no yuav muaj qee yam teeb meem, xws li kev txo qis hauv qib ntawm lub cev tiv thaiv, uas, vim li ntawd, ua rau lub qhov txhab tsis zoo, lub raum tsis ua haujlwm, cov hlab ntsha puas, nce ntshav lipids, kev pheej hmoo ntawm cov hlab ntsha (peripheral), rog rog, thiab plawv nres thiab/los yog mob stroke.

khoom qab zib - zoo lossis phem

Ntau tus neeg uas ntshai tsam noj qabzib lossis fructose tig mus rau cov khoom qab zib zoo li aspart lossis sucrapose. Txawm li cas los xij, lawv kuj muaj lawv qhov tsis zoo. Vim qhov tseeb tias cov tshuaj no yog cov khoom siv tshuaj lom neeg cov tshuaj neurotoxic, cov tshuaj hloov pauv tuaj yeem ua rau mob taub hau, thiab tseem muaj kev pheej hmoo ntawm kev mob qog noj ntshav. Yog li, qhov kev xaiv no, zoo li yav dhau los, tsis yog 100%.

Txhua lub ntiaj teb nyob ib puag ncig peb cuam tshuam rau tib neeg lub cev, thiab tsis muaj leej twg tuaj yeem tiv thaiv peb tus kheejtxhua yam kab mob. Txawm li cas los xij, raws li qee qhov kev paub, peb tuaj yeem tswj cov txheej txheem ntawm qhov tshwm sim ntawm qee yam mob. Nws zoo ib yam nrog kev siv sucrose: tsis txhob tso tseg nws, raws nraim tib yam li niaj hnub siv. Koj yuav tsum nrhiav "golden" txhais tau tias thiab lo rau cov kev xaiv zoo tshaj plaws. Cov kev xaiv uas koj lub cev yuav hnov zoo thiab qhia koj tias "ua tsaug" loj heev! Yog li xaiv hom qab zib uas koj xav siv thiab tau txais lub zog txhua hnub.
