Qhov sib txawv tseem ceeb ntawm flavonoids thiab polyphenols yog tias cov flavonoids feem ntau muaj 15-carbon skeleton hos cov polyphenols muaj cov pob txha sib txawv.
Flavonoids yog ib pawg ntawm polyphenols. Txawm li cas los xij, tsis yog txhua tus polyphenols yog flavonoids. Ntxiv mus, flavonoids yog ib txwm tshwm sim sib txuas thaum polyphenols tuaj yeem ua ntuj, semi-synthetic lossis hluavtaws.
Dab tsi yog Flavonoids?
Flavonoids yog ib pawg ntawm cov tshuaj polyphenolic. Lawv yog cov metabolites theem nrab ntawm cov nroj tsuag thiab fungus. Thaum xav txog cov qauv tshuaj ntawm flavonoids, lawv feem ntau muaj 15-carbon skeleton. Nyob ntawd, nws muaj ob lub nplhaib phenyl thiab lub nplhaib heterocyclic.
Daim duab 01: Cov Qauv Tseem Ceeb ntawm Flavonoids
Yog li ntawd, peb tuaj yeem hu tus qauv ua C6-C3-C6. Muaj peb chav kawm loj ntawm flavonoids raws li hauv qab no:
- YBioflavonoids
- Isoflavonoids Y
Neoflavonoids Neoflavonoids
Txhua cov qauv saum toj no yog ketone muaj cov khoom sib txuas. Thaum xav txog kev ua haujlwm ntawm cov tebchaw no hauv cov nroj tsuag, nws txoj haujlwm tseem ceeb tshaj plaws yog tias nws ua raws li cov xim cog rau paj xim. Nyob ntawd, nws ua rau daj, liab lossis xiav xim. Cov xim no muaj nyob rau ntawm cov paj ntawm paj raws li lub tswv yim los nyiam cov tsiaj pollinator xws li kab. Ntxiv mus, cov tebchaw no koom nrog UV pom, nitrogen fixation, floral pigmentation, thiab lwm yam.
Dab tsi yog Polyphenols?
Polyphenols yog cov tebchaw loj uas muaj ntau tshaj ib pawg phenolic hauv lawv cov qauv tshuaj. Cov tebchaw no yog ntuj lossis hluavtaws. Qee zaum muaj cov ntaub ntawv semi-synthetic thiab. Feem ntau, cov no yog cov tebchaw loj heev. Tsis tas li ntawd, cov tshuaj no zoo li tso rau hauv cell vacuoles. Qhov hnyav molecular ntawm cov tebchaw no tso cai rau lawv kom nrawm nrawm thoob plaws cell membranes.
Ntxiv mus, cov tebchaw no muaj cov tshuaj heteroatomic uas tsis yog pawg hydroxyl. Nyob ntawd, ether pawg thiab ester pawg muaj ntau. Thaum xav txog cov khoom siv tshuaj lom neeg ntawm cov molecules, lawv muaj UV / pom kev nqus, vim muaj cov pab pawg muaj ntxhiab. Tsis tas li ntawd, lawv muaj autofluorescence zog. Tsis tas li ntawd, lawv yog cov reactive heev rau oxidation.

Thaum xav txog kev siv cov tshuaj no, tib neeg ib txwm siv nws ua cov tshuaj zas xim. Ntxiv mus, muaj qee qhov kev siv tshuaj lom neeg xws li;
- YKev tso tawm ntawm kev loj hlob hormone hauv cov nroj tsuag
- Txhim kho cov tshuaj hormones hauv cov nroj tsuag
- Ua raws li kev taw qhia cov molecules hauv ripening thiab lwm yam kev loj hlob
- Kev tiv thaiv kab mob microbial.
Qhov txawv ntawm Flavonoids thiab Polyphenols yog dab tsi?
Flavonoids yog ib pawg ntawm cov tshuaj polyphenolic thiab polyphenols yog cov sib txuas loj uas muaj ntau tshaj li ib pawg phenolic hauv lawv cov qauv tshuaj. Qhov sib txawv tseem ceeb ntawm flavonoids thiab polyphenols yog tias cov flavonoids feem ntau muaj 15-carbon skeleton hos cov polyphenols muaj cov pob txha sib txawv. Ntxiv mus, flavonoids yog ib txwm tshwm sim sib txuas thaum polyphenols tuaj yeem yog ntuj, semi-synthetic lossis hluavtaws. Yog li, qhov no yog lwm qhov sib txawv ntawm flavonoids thiab polyphenols.
Summary – Flavonoids vs Polyphenols
Txhua flavonoids yog polyphenols, tab sis tsis yog tag nrho cov polyphenols yog flavonoids. Yog li, qhov sib txawv tseem ceeb ntawm flavonoids thiab polyphenols yog tias cov flavonoids feem ntau muaj 15-carbon skeleton whereas polyphenols muaj cov pob txha carbon sib txawv.
