Ib qho piv txwv ntawm tsawg hydrophilic pawg yog carbonyl pawg (C=O), ib qho tsis muaj nqi tab sis polar (muaj ib feem zoo thiab ib nrab nqi tsis zoo) pab pawg ua haujlwm. Carbonyls muaj nyob rau hauv ntau yam lom lom molecules, nrog rau cov proteins, peptides, thiab carbohydrates.
Puas yog carbonyl pawg hydrophilic?
Cov pab pawg ua haujlwm feem ntau yog cais raws li hydrophobic lossis hydrophilic nyob ntawm lawv cov nqi lossis polarity. … Lwm pab pawg ua haujlwm, xws li pab pawg carbonyl, muaj qee qhov tsis zoo ntawm cov pa oxygen atom uas tuaj yeem tsim hydrogen bonds nrog dej molecules, dua ua cov molecule ntau hydrophilic.
Pab dab tsi yog hydrophilic?
Hydrophilic functional pawg muaj xws li hydroxyl pawg (ua rau muaj cawv txawm tias tseem pom muaj suab thaj, thiab lwm yam), pawg carbonyl (ua rau aldehydes thiab ketones), pawg carboxyl (ua rau nyob rau hauv carboxylic acids), amino pawg (piv txwv li, raws li pom nyob rau hauv cov amino acids), sulfhydryl pawg (muab nce rau thiols, piv txwv li, raws li pom …
Puas yog carbonyl pawg polar?
Yog li, cov molecules uas muaj cov pa roj carbonyl pawg yog polar. Cov tshuaj uas muaj cov pab pawg carbonyl muaj cov ntsiab lus melting ntau dua thiab cov ntsiab lus kub dua li cov hydrocarbons uas muaj tib cov pa roj carbon atoms thiab soluble ntau dua hauv cov kuab tshuaj polar xws li dej.
Pab pawg ua haujlwm twg ua rau carbohydrate hydrophilic?
Txhua cov pa roj carbon yuav tsumtsim plaub daim ntawv cog lus; feem ntau yuav koom nrog ob leeg ib leeg hydrogen atom thiab hydroxyl pawg (-OH). Nws yog pawg hydroxyl no uas muab cov carbohydrates rau lawv cov polar, hydrophilic xwm - thiab tso cai rau lawv sib koom ua ke los ntawm cov txheej txheem ntawm lub cev qhuav dej synthesis los tsim cov disaccharides thiab polysaccharides.
