Qhov Tseem Ceeb - Anthocyanin vs Anthocyanidin
Anthocyanin thiab anthocyanidins yog suav tias yog cov khoom cog pigments pom nyob rau hauv cov nroj tsuag siab dua ntawm lub nceeg vaj. Lawv feem ntau pom nyob rau hauv txiv hmab txiv ntoo thiab paj tab sis kuj nyob rau hauv nplooj, stems, thiab keeb kwm. Lawv nyob rau hauv qeb ntawm bioflavonoids. Lawv sib koom ua ke; cov flavylium ion. Anthocyanidins yog cov tsis muaj suab thaj analogues rau anthocyanins thaum anthocyanins yog tsim los ntawm kev sib txuas ntawm cov suab thaj rau anthocyanidins. Qhov no yog qhov sib txawv tseem ceeb ntawm anthocyanin thiab anthocyanidin.
Anthocyanins yog dab tsi?
Anthocyanins yog ib pawg ntawm cov nroj tsuag pigments uas muaj nyob rau hauv pawg flavonoids lossis bioflavonoids. Lawv tsuas yog tsim nyob rau hauv cov nroj tsuag siab dua. Nws feem ntau tshwm sim hauv cov txiv hmab txiv ntoo thiab paj uas muab xim liab thiab xiav; Nws tseem muaj nyob rau hauv stems, nplooj, thiab keeb kwm. Cov xim ntawm anthocyanins nyob ntawm qib acidity. Nyob rau hauv acidic tej yam kev mob, anthocyanins tshwm nyob rau hauv liab whilst, nyob rau hauv tsawg acidic tej yam kev mob, lawv tshwm nyob rau hauv xiav. Anthocyanins tuaj yeem muab faib ua ob pawg: anthocyanidin aglycons thiab anthocyanin glycosides. Cov qauv tseem ceeb ntawm anthocyanins yog flavylium ion nrog xya pawg sib txawv. Cov pab pawg sab tuaj yeem yog hydrogen atom, hydroxide lossis pawg methoxy.
Daim duab 01: Tsaus liab doog xim ntawm Pansies yog vim Anthocyanin
Anthocyanins muaj cov haujlwm sib txawv hauv cov nroj tsuag lub cev. Lawv ua haujlwm ua antioxidants uas tiv thaiv cov nroj tsuag lub cev tiv thaiv dawb radicals uas tsim los ntawm UV hluav taws xob uas cuam tshuam DNA thiab ua rau cell tuag. Lawv kuj tseem suav hais tias yog qhov tseem ceeb ntawm cov nroj tsuag pollination thiab kev yug me nyuam vim tias cov kab mob pollinating tau nyiam vim nws cov xim liab thiab xiav. Cov tshuaj anthocyanins xws li cyaniding-3-glucoside raug suav tias yog cov tshuaj tua kab mob.
Anthocyanidins yog dab tsi?
Anthocyanidin, yog hom bio-flavonoid, yog cov tshuaj lom neeg uas muaj lub luag haujlwm rau pigmentation ntawm cov nroj tsuag. Lawv yog cov analogues tsis muaj qab zib ntawm anthocyanins uas yog raws li flavylium ion. Ntawm no, cov txee ion feem ntau yog cov tshuaj chloride thiab cov nqi zoo no txawv cov anthocyanidins los ntawm lwm cov flavonoids.
Anthocyanidins suav tias yog cov tshuaj antioxidant flavonoid uas muab cov xim liab lossis xim liab rau cov txiv hmab txiv ntoo thiab zaub xws li txiv hmab txiv ntoo, cherries, raspberries, blueberries, plums, beets thiab liab doog. Nws kuj muab cov xim ci rau paj. Qhov no yuav pab kom nyiam ntau tus neeg sawv cev ntawm pollination ntawm lub paj. Nroj tsuag kuj tuav lawv cov matured progeny vim pigmentation muab los ntawm anthocyanidins. Anthocyanidins muab kev tiv thaiv rau cov ntaub so ntswg photosynthetic hauv cov nroj tsuag los ntawm tshav ntuj ncaj qha.
Daim duab 02: Anthocyanidine qauv
Anthocyanidins nyob ntawm pH kom muaj kev ruaj ntseg. Cov xim anthocyanidins muaj nyob rau hauv pH qis thaum cov xim tsis muaj xim ntawm chalcones muaj nyob rau hauv pH ntau dua.
Dab tsi zoo sib xws ntawm Anthocyanin thiab Anthocyanidin?
- Ob qho anthocyanins thiab anthocyanidins yog cov xim cog qoob loo.
- Cov qauv tseem ceeb yog flavylium ions.
- Ob leeg ua cov tshuaj antioxidants uas tiv thaiv DNA los ntawm cov dawb radicals tsim.
- Lawv yog pH nyob ntawm.
- Ob lub pigments pab hauv pollination uas attracts pollinating agents.

Summary – Anthocyanin vs Anthocyanidin
Anthocyanins thiab anthocyanidins yog ob yam tshwj xeeb ntawm cov ntsiab lus hauv cov xim cog qoob loo uas koom nrog pawg, bioflavonoids. Ob lub tebchaw sib koom ua ke cov qauv tseem ceeb, uas yog flavylium ion. Anthocyanidins yog cov tshuaj tsis muaj piam thaj ntawm anthocyanins. Anthocyanins yog tsim los ntawm kev sib ntxiv ntawm cov suab thaj rau ntau pawg ntawm flavylium ion. Qhov no yog qhov sib txawv tseem ceeb ntawm anthocyanin thiab anthocyanidin. Txij li muaj ntau hom suab thaj tam sim no, lawv tuaj yeem nyob ntawm cov pab pawg sib txawv, ua rau muaj ntau hom anthocyanin. Ob lub tebchaw yog pH nyob ntawm thiab muaj cov khoom antioxidant. Lawv pab nyob rau hauv tus txheej txheem ntawm pollination thiab ua raws li larvae repellants uas ua mob rau lub cev cog.
