Umahluko phakathi kweemolekyuli ze-hydrophobic kunye ne-hydrophilic molecules

Ziziphi iimolekyuli ze-hydrophobic kunye ne-hydrophilic molekyuli?

I iimolekyuli ze-hydrophobic Ngabo abo banganyibilikiyo emanzini, ekubeni abanabudlelwane nawo. Njengoko igama labo libonisa, ezi molekyuli "ziyawoyika" amanzi. Kwelinye icala, i iimolekyuli ze-hydrophilic Zezo zinobudlelwane kwaye zinyibilika emanzini.

Yintoni umahluko phakathi kwazo?

Umahluko omkhulu phakathi kwe-hydrophobic kunye ne-hydrophilic molekyuli kukukwazi kwabo ukunyibilika emanzini. Iimolekyuli zeHydrophobic zigxothwa ngamanzi, ngelixa iimolekyuli ze-hydrophilic zitsalwa kuyo. Lo mahluko ubangelwa ukubunjwa kwama-molecule kwaye, ngokukodwa, i-polarity yabo.

Iimolekyuli zeHydrophobic

Iimolekyuli zeHydrophobic zihlala ziziamolekyuli ezingezizo iipolar, ezinje ngeehydrocarbons, amafutha kunye namafutha. Ekubeni bengenawo umrhumo wombane kwisakhiwo sabo, abasebenzisani ne-dipoles yamanzi, okuyi-molecule ye-polar. Ke ngoko, badla ngokuhlangana kunye kwaye bahlale kunye kude namanzi, njengoko oku kunciphisa ukunxibelelana nawo.

Iimolekyuli zeHydrophilic

Ngokwahlukileyo koko, iimolekyuli ze-hydrophilic zidla ngokuba yi-polar, oko kukuthi, zinentlawulo elungileyo kwindawo enye yemolekyuli kunye necala elibi kwelinye. Oku kubavumela ukuba benze i-ionize emanzini kwaye benze iibhondi ze-hydrogen kunye neemolekyuli zamanzi ezijikelezileyo.

Imizekelo yeemolekyuli ze-hydrophobic kunye ne-hydrophilic molecules

Eminye imizekelo Iimolekyuli ze-Hydrophobic ziquka i-lipids, njenge-triglycerides kunye ne-wax. Ezi molekyuli zibalulekile ekusebenzeni kweeseli kunye nokugcinwa kwe-membrane yeplasma. Nangona kunjalo, zinokuba yingozi ukuba ziqokelela ngokugqithiseleyo emzimbeni.

Kwelinye icala, eminye imizekelo yeemolekyuli ze-hydrophilic ziquka i-glucose, i-amino acids, kunye ne-nucleic acids. Ezi molekyuli zibalulekile ekusebenzeni kweeseli kunye nokuhlanganiswa kweeprotheni kunye neDNA.

Isiphelo

Isishwankathelo, iimolekyuli ze-hydrophobic kunye ne-hydrophilic molecules zimbini iintlobo ezahlukeneyo zeekhompawundi, ezahlukileyo ngokukwazi ukunyibilika emanzini. Iimolekyuli zeHydrophobic zigxothwa ngamanzi, ngelixa iimolekyuli ze-hydrophilic zinyibilika kuyo. Lo mahluko ubangelwa yipolarity yeemolekyuli, kwaye ibaluleke kakhulu kwi-biochemistry kunye ne-cell biology.
