Dab tsi yog qhov txawv ntawm anthocyanins thiab proanthocyanidins?

Anthocyanins thiab proanthocyanidins yog ob chav kawm ntawm cov nroj tsuag tebchaw uas tau txais kev saib xyuas rau lawv cov txiaj ntsig kev noj qab haus huv thiab cov khoom antioxidant.Thaum lawv sib koom qee qhov zoo sib xws, lawv kuj muaj qhov sib txawv ntawm lawv cov qauv tshuaj, qhov chaw, thiab cov txiaj ntsig kev noj qab haus huv.Kev nkag siab qhov sib txawv ntawm ob lub tebchaw no tuaj yeem muab kev nkag siab zoo rau lawv lub luag haujlwm tshwj xeeb hauv kev txhawb nqa kev noj qab haus huv thiab tiv thaiv kab mob.

Anthocyaninsyog cov dej-soluble pigments teej tug mus rau pawg flavonoid ntawm cov tebchaw.Lawv muaj lub luag haujlwm rau cov xim liab, ntshav, thiab xiav hauv ntau cov txiv hmab txiv ntoo, zaub, thiab paj.Cov khoom noj uas muaj anthocyanins muaj xws li cov txiv hmab txiv ntoo (xws li blueberries, strawberries, thiab raspberries), zaub qhwv liab, txiv hmab txiv ntoo liab, thiab eggplants.Anthocyanins paub txog lawv cov khoom antioxidant, uas pab tiv thaiv cov hlwb los ntawm kev puas tsuaj los ntawm cov dawb radicals.Cov kev tshawb fawb tau qhia tias anthocyanins tuaj yeem muaj txiaj ntsig zoo rau kev noj qab haus huv, xws li txo qis kev pheej hmoo ntawm cov kab mob plawv, txhim kho kev paub txog kev ua haujlwm, thiab tiv thaiv qee yam mob qog noj ntshav.

Ntawm qhov tod tes,proanthocyanidinsyog ib chav kawm ntawm flavonoid tebchaw kuj hu ua condensed tannins.Lawv muaj nyob rau hauv ntau yam khoom noj uas cog, nrog rau txiv hmab txiv ntoo, txiv apples, cocoa, thiab qee yam txiv ntoo.Proanthocyanidins paub txog lawv lub peev xwm los khi rau cov protein, uas ua rau lawv muaj txiaj ntsig zoo rau kev noj qab haus huv xws li txhawb kev mob plawv, txhawb kev noj qab haus huv ntawm daim tawv nqaij, thiab tiv thaiv oxidative kev nyuaj siab.Proanthocyanidins kuj tau lees paub rau lawv lub luag haujlwm hauv kev txhawb nqa txoj kev noj qab haus huv ntawm cov urinary los ntawm kev tiv thaiv kev ua kom cov kab mob adhesion ntawm cov kab mob urinary.

Ib qho ntawm qhov sib txawv tseem ceeb ntawm anthocyanins thiab proanthocyanidins nyob hauv lawv cov qauv tshuaj.Anthocyanins yog glycosides ntawm anthocyanidins, uas txhais tau hais tias lawv muaj ib qho anthocyanidin molecule txuas rau lub suab thaj molecule.Anthocyanidins yog aglycone cov ntaub ntawv ntawm anthocyanins, txhais tau tias lawv yog cov tsis qab zib ib feem ntawm cov molecule.Hauv qhov sib piv, proanthocyanidins yog cov polymers ntawm flavan-3-ols, uas yog tsim los ntawm catechin thiab epicatechin units txuas ua ke.Qhov sib txawv ntawm cov qauv no ua rau muaj kev hloov pauv hauv lawv lub cev thiab tshuaj lom neeg, nrog rau lawv cov dej num lom neeg.

Lwm qhov sib txawv tseem ceeb ntawm anthocyanins thiab proanthocyanidins yog lawv cov kev ruaj ntseg thiab bioavailability.Anthocyanins yog cov tshuaj tsis ruaj khov uas tuaj yeem yooj yim degraded los ntawm yam xws li kub, lub teeb, thiab pH hloov.Qhov no tuaj yeem cuam tshuam rau lawv cov bioavailability thiab cov txiaj ntsig kev noj qab haus huv.Ntawm qhov tod tes, proanthocyanidins ruaj khov thiab tiv taus kev puas tsuaj, uas tuaj yeem ua rau lawv cov bioavailability ntau dua thiab kev ua haujlwm lom hauv lub cev.

Hais txog cov txiaj ntsig kev noj qab haus huv, ob qho tib si anthocyanins thiab proanthocyanidins tau kawm txog lawv lub luag haujlwm tseem ceeb hauv kev tiv thaiv kab mob ntev thiab txhawb kev noj qab haus huv tag nrho.Anthocyanins tau cuam tshuam nrog kev tiv thaiv kab mob, tiv thaiv qog noj ntshav, thiab cov teebmeem neuroprotective, nrog rau cov txiaj ntsig ntawm cov hlab plawv xws li kev txhim kho cov hlab ntsha thiab txo qhov kev pheej hmoo ntawm atherosclerosis.Proanthocyanidins tau tshawb xyuas rau lawv cov tshuaj tiv thaiv kab mob antioxidant, tiv thaiv kab mob, thiab tiv thaiv kab mob microbial, nrog rau lawv lub peev xwm los txhawb kev mob plawv, txhim kho daim tawv nqaij elasticity, thiab tiv thaiv lub hnub nyoog txog kev paub txog kev poob qis.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev noj qab haus huv cuam tshuam ntawm anthocyanins thiab proanthocyanidins tseem tab tom tshawb fawb, thiab xav tau kev tshawb fawb ntxiv kom nkag siab txog lawv cov txheej txheem ntawm kev ua thiab kev siv tshuaj kho mob.Tsis tas li ntawd, bioavailability thiab metabolism ntawm cov tebchaw hauv tib neeg lub cev tuaj yeem sib txawv nyob ntawm seb muaj pes tsawg tus neeg sib txawv, cov khoom noj khoom haus matrix, thiab cov txheej txheem ua.

Hauv kev xaus, anthocyanins thiab proanthocyanidins yog ob chav kawm ntawm cov nroj tsuag tebchaw uas muaj ntau yam txiaj ntsig kev noj qab haus huv vim lawv cov antioxidant thiab bioactive zog.Thaum lawv qhia qee qhov zoo sib xws ntawm lawv cov teebmeem antioxidant thiab cov txiaj ntsig kev noj qab haus huv, lawv kuj muaj qhov sib txawv ntawm lawv cov qauv tshuaj, qhov chaw, kev ruaj ntseg, thiab bioavailability.Kev nkag siab txog cov yam ntxwv tshwj xeeb ntawm cov tebchaw no tuaj yeem pab peb txaus siab rau lawv lub luag haujlwm sib txawv hauv kev txhawb nqa kev noj qab haus huv thiab tiv thaiv kab mob.
