Phospholipids muaj glycerol molecule, ob fatty acids, thiab ib pawg phosphate uas hloov los ntawm cawv. Cov pab pawg phosphate yog qhov tsis zoo ntawm lub taub hau polar, uas yog hydrophilic. Cov kab mob fatty acid yog cov uas tsis muaj roj, tsis muaj polar tails, uas yog hydrophobic
YPuas yog phospholipid bilayer hydrophilic lossis hydrophobic?
Cov phospholipid bilayer muaj ob txheej ntawm phospholipids, nrog a hydrophobic, los yog dej-ntxub, sab hauv thiab hydrophilic, los yog dej-hlub, sab nrauv. Cov pawg hydrophilic (polar) lub taub hau thiab hydrophobic tails (fatty acid chains) tau piav qhia nyob rau hauv ib qho phospholipid molecule.
Vim li cas phospholipids hydrophilic thiab hydrophobic?
Phospholipids yog amphipathic molecules. Qhov no txhais tau hais tias lawv muaj hydrophilic, polar phosphate taub hau thiab ob lub hydrophobic fatty acid tailsCov khoom ntawm phospholipids ua rau lawv taw qhia lawv tus kheej, yog li lub taub hau phosphate tuaj yeem cuam tshuam nrog dej thiab fatty acid. tails ua tsis tau, yog li tsim ib tug bilayer.
YVim li cas phospholipids insoluble hauv dej?
Ua raws li txoj cai ntawm "zoo li yaj zoo li", lub taub hau hydrophilic ntawm phospholipid molecule dissolves hauv dej. Qhov ntev fatty acid chains ntawm phospholipid yog nonpolar, thiab yog li zam dej vim lawv insolubility.
Puas yog phospholipids hydrophobic lossis hydrophilic quizlet?
Phospholipids muaj ob thaj chaw hydrophobic thiab hydrophilichauv ib lub molecule. Lub taub hau phosphate yog hydrophilic vim nws yog polar, ua rau nws tsim hydrogen bonds nrog dej. Hauv qhov sib piv, ob qhov ntev fatty acid tails yog hydrophobic vim tias lawv tsis yog polar thiab tsis tsim hydrogen bonds nrog dej.
