Qhov sib txawv tseem ceeb ntawm naringin thiab naringenin yog naringin muaj ib qho iab saj, whereas naringenin tasteless thiab colorless.
Naringin yog hom flavonoid uas tshwm sim hauv cov txiv hmab txiv ntoo citrus. Naringenin yog ib yam khoom uas tsis muaj tsw thiab tsis muaj xim flavanone.
Naringin yog dab tsi?
Naringin yog hom flavonoid uas tshwm sim hauv cov txiv hmab txiv ntoo citrus. Peb tuaj yeem hu nws ua flavanone-7-O-glycoside uas los ntawm naringenin thiab disaccharide neohesperidose. Peb tuaj yeem pom cov flavonoid tshwj xeeb hauv cov txiv kab ntxwv. Nyob rau hauv grapefruits, nws yog lub luag hauj lwm rau lub iab saj ntawm txiv hmab txiv ntoo. Yog li ntawd, thaum ua lag luam tsim cov kua txiv hmab txiv ntoo, peb siv cov enzyme naringinase kom tshem tawm cov iab ntawm cov kua txiv hmab txiv ntoo. Txawm li cas los xij, tib neeg lub cev muaj peev xwm metabolize cov tshuaj no rau hauv aglycone naringenin uas tsis iab saj, thiab cov metabolism no tuaj yeem pom hauv plab.
Daim duab 01: Cov Qauv Tshuaj ntawm Naringin
Feem ntau, ib qho flavonoid compound muaj 15 carbon atoms teem rau hauv 3 lub nplhaib qauv. Ntawm cov qauv ntawm cov nplhaib no, 2 lub nplhaib yog benzene rings uas txuas rau ib leeg los ntawm 3-carbon saw. Naringin muaj cov qauv flavonoid yooj yim uas muaj ib lub rhamnose thiab ib chav piam thaj uas txuas rau aglucone feem ntawm cov khoom no (tseem hu ua naringenin), uas tshwm sim ntawm txoj haujlwm carbon-7.
Thaum xav txog kev siv cov tshuaj no, nws yog qhov tseem ceeb tshaj li cov khoom qab zib vim tias thaum cov tshuaj no tau kho nrog KOH (potassium hydroxide), ua raws li catalytical hydrogenation, nws muab ib qho naringin dihydrochalcone. Cov khoom uas tau tshwm sim no yog kwv yees li 300 txog 1800 npaug ntawm qab zib dua li cov suab thaj ib txwm.
Txawm li cas los xij, vim yog inhibition ntawm qee cov tshuaj-metabolizing cytochrome P450 enzymes los ntawm cov tshuaj no, nws raug suav hais tias yog cov tshuaj lom neeg ntawm qhov siab. Cov tshuaj lom ntawm naringin hauv cov nas yog nyob ib ncig ntawm 2000 mg / kg. Feem ntau, cov kua txiv hmab txiv ntoo muaj txog 400 mg / L.
Naringenin yog dab tsi?
Naringenin yog ib qho tsis muaj tsw thiab tsis muaj xim flavanone. Nws yog hom flavonoid thiab tshwm sim raws li qhov tseem ceeb ntawm flavanone hauv txiv kab ntxwv. Peb kuj tuaj yeem pom cov khoom no hauv ntau cov txiv hmab txiv ntoo thiab tshuaj ntsuab, suav nrog txiv kab ntxwv, txiv kab ntxwv, txiv kab ntxwv qaub, txiv kab ntxwv, txiv lws suav, thiab lwm yam. Cov metabolism ntawm cov tshuaj no tshwm sim nyob rau hauv lub xub ntiag ntawm naringenin 8-dimethylallyltranferase enzyme.
Yog tias peb saib cov qauv tshuaj ntawm naringenin, nws muaj lub cev pob txha ntawm cov flavanone ib txwm muaj peb pawg -OH ntawm 4, 5 thiab 7 carbon txoj haujlwm. Peb tuaj yeem pom cov tshuaj no hauv ob hom: hauv nws daim ntawv aglycol lossis hauv nws daim ntawv glycosidic.
Daim duab 02: Cov Qauv Tshuaj ntawm Naringenin
Thaum xav txog kev ua haujlwm lom neeg ntawm naringenin, nws muaj cov tshuaj tiv thaiv kab mob rau qee cov kab mob; tuaj yeem txo tus kab mob siab C los ntawm cov kab mob siab hepatocyte hauv cell kab lis kev cai; muaj cov khoom tseem ceeb antioxidant thiab anticancer zog, thiab lwm yam
Dab tsi yog qhov zoo sib xws ntawm Naringin thiab Naringenin?
- Naringin thiab Naringenin yog cov tshuaj flavanone.
- Ob leeg yog cov organic tebchaw uas muaj peb-ntiv nplhaib qauv ib molecule.
Qhov txawv ntawm Naringin thiab Naringenin yog dab tsi?
Naringin yog hom flavonoid uas tshwm sim hauv cov txiv hmab txiv ntoo citrus. Naringenin yog ib yam khoom uas tsis muaj tsw thiab tsis muaj xim flavanone. Qhov sib txawv tseem ceeb ntawm naringin thiab naringenin yog naringin muaj ib qho iab saj, whereas naringenin tasteless thiab colorless. Ntxiv mus, naringin feem ntau tshwm sim hauv cov txiv hmab txiv ntoo citrus, suav nrog txiv kab ntxwv qaub, whereas naringenin tshwm sim hauv ntau cov txiv hmab txiv ntoo thiab tshuaj ntsuab, suav nrog txiv kab ntxwv qaub, bergamot, qaub txiv kab ntxwv, tart cherries, txiv lws suav, thiab lwm yam.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm naringin thiab naringenin hauv daim ntawv tabular.
Summary – Naringin vs Naringenin
Naringin yog ib hom flavonoid uas tshwm sim hauv cov txiv hmab txiv ntoo citrus, thaum naringenin yog ib yam khoom tsis muaj tsw thiab tsis muaj xim flavanone. Qhov sib txawv tseem ceeb ntawm naringin thiab naringenin yog naringin muaj iab saj whereas naringenin tasteless thiab colorless.
