Molecular Structure thiab Polarity Qhov sib txawv ntawm cov chlorophylls, uas yog ntau dua polar dua β-carotene yog me ntsis: chlorophyll a muaj methyl pawg (Y=CH3) nyob rau hauv ib txoj hauj lwm qhov twg chlorophyll b muaj aldehyde (Y=CHO). Qhov no ua rau chlorophyll b me ntsis ntau dua polar dua chlorophyll a.
Puas yog chlorophylls polar?
Nco ntsoov, chlorophylls thiab carotenoids yog hydrophobic lossis nonpolarthiab yuav yaj hauv cov kuab tshuaj tsawg dua polar, hos anthocyanins yog extractable thiab soluble nyob rau hauv ntau polar solvents xws li dej.
YPuas yog spinach polar lossis nonpolar?
Ib qho tshuaj tov ntawm hexanes thiab acetone yuav tsum tau siv vim acetone yog polar heev, thaum hexane nyob rau hauv tsis-polar, thiab spinach nplooj muaj ob qho tib si tsis-polar thiab polar pigments nyob rau hauv lawv uas yog ib qho tseem ceeb nyob rau hauv extraction thiab kev soj ntsuam ntxiv.
Puas yog carotenoids polar?
Carotenoids yog nonpolar compounds, uas tau muab faib ua ob pawg, piv txwv li, ntau cov polar compounds hu ua xanthophylls, lossis oxycarotenoids, thiab nonpolar hydrocarbon carotenes.
YPuas Xanthophyll polar lossis nonpolar?
Xanthophylls yog ntau polar vim tias lawv muaj cawv, ketone, aldehyde, acid, lossis epoxide pawg, thiab yog li yuav muab rho tawm nrog ethyl cawv lossis sib tov ntawm ethyl cawv thiab sib piv tsawg dua. polar solvents, xws li chloroform (Houghton and Raman, 1998).
