Tsev neeg carotenoid Qhov txawv ntawm ob pawg yog tshuaj: xanthophylls muaj oxygen, thaum carotene yog hydrocarbons thiab tsis muaj oxygen. Tsis tas li, ob qhov nqus qhov sib txawv ntawm lub teeb thaum lub sijhawm cog cov txheej txheem photosynthesis, yog li xanthophylls muaj xim daj dua thaum carotenes yog txiv kab ntxwv.
Xanthophyll yog xim dab tsi?
Xanthophylls yog yellow pigments uas yog ib qho tseem ceeb ntawm pawg carotenoid. Lo lus xanthophylls yog tsim los ntawm Greek lo lus xanthos, lub ntsiab lus daj, thiab phyllon, lub ntsiab lus nplooj.
Xanthophylls muaj nuj nqi dab tsi?
Xanthophylls tuaj yeem ua haujlwm raws li khoom siv lub teeb-sau pigments, raws li cov khoom tsim nyob hauv LHC, thiab raws li cov molecules xav tau rau kev tiv thaiv cov kab mob photosynthetic los ntawm cov teeb meem tshuaj lom ntawm lub teeb.
Yuav ua li cas ntawm xanthophyll hauv photosynthesis?
Xanthophylls tuaj yeem ua haujlwm raws li khoom siv lub teeb-sau pigments, raws li cov khoom tsim nyob hauv LHC, thiab raws li cov molecules xav tau rau kev tiv thaiv cov kab mob photosynthetic los ntawm cov teeb meem tshuaj lom ntawm lub teeb.
Lub hom phiaj ntawm carotene thiab xanthophylls hauv cov nroj tsuag yog dab tsi?
Carotenes thiab lawv cov pa oxygenated derivatives, xanthophylls, yog cov qauv tsim ntawm cov khoom siv photosynthetic thiab pab txhawb kom nce ob lub teeb-txiav thiab photoprotective peev ntawm cov photosystems.
