Hydrophobic txhais tau tias uas lub molecule yog "ntshai" dej. Cov tails ntawm phospholipid yog hydrophobic , txhais tau tias lawv yog nyob rau hauv lub membrane. Hydrophilic txhais tau tias uas lub molecule muaj affinity rau dej.

Tib neeg kuj nug, cov ntsiab lus hydrophilic thiab hydrophobic txhais li cas?

Hydrophilic txhais tau hais tias muaj ib tug nyiam sib tov nrog, yaj nyob rau hauv, los yog wetted los ntawm dej. Hydrophobic . txhais tau hais tias tending rau repel los yog tsis sib tov nrog dej. Lawv cuam tshuam rau cov qauv ntawm cov cell membrane. vim phospholipids muaj a hydrophilic taub hau nrog ob hydrophobic qab.

Tsis tas li ntawd, dab tsi yog cov tshuaj hydrophilic? Hydrophilic Txhais. A hydrophilic molecule lub yam khoom yog attracted rau dej. Dej yog ib tug polar molecule uas ua raws li cov kuab tshuaj, dissolving lwm polar thiab hydrophilic tshuaj . Hauv biology, ntau tshuaj yog hydrophilic , uas tso cai rau lawv tawg mus thoob plaws hauv lub cell los yog kab mob.

Yog li ntawd, cov ntsiab lus hydrophilic thiab hydrophobic txhais li cas quizlet?

Hydrophilic txhais tau tias attracted rau dej thiab hydrophobic txhais tau tias repelled los ntawm dej.

Cov piv txwv ntawm hydrophilic molecules yog dab tsi?

Piv txwv li: Polar covalent compounds xws li cawv xws li C2H5OH (ethanol) thiab ketones xws li (CH3)2C = = O (acetone)], suab thaj, ionic compounds xws li KCl), amino acids, thiab phosphate esters. hydrophilic txhais tau tias dej -hlub, tab sis feem ntau yog siv rau hauv cov ntsiab lus ntawm cov khoom uas yooj yim wetted, tab sis tsis yaj.
