Triglycerides suav nrog peb fatty acids uas txuas rau glycerol, yielding hydrophobic molecule. Phospholipids muaj ob qho tib si hydrophobic hydrocarbon chains thiab polar taub hau pawg, ua rau lawv amphipathic thiab muaj peev xwm ntawm kev tsim tshwj xeeb ua haujlwm loj scale lug.

Ib yam li ntawd, koj tuaj yeem nug, puas yog fatty acids Amphipathic?

Structure [edit] Kev tsim ntawm micelle yog ib qho lus teb rau qhov amphipathic xwm ntawm fatty acids , txhais tau hais tias lawv muaj ob thaj chaw hydrophilic (polar taub hau pawg) nrog rau thaj tsam hydrophobic (cov saw ntev hydrophobic). Lawv fim rau hauv dej vim lawv yog polar.

Tsis tas li ntawd, dab tsi yog amphipathic? Ib amphipathic molecule yog ib qho molecule uas muaj ob qho tib si polar thiab tsis-polar. Phospholipids, piv txwv li, muaj cov tsis muaj polar fatty acid "tails" thiab polar phosphate "taub hau." "Polarity" yog cov cuab yeej tseem ceeb ntawm cov molecules uas txiav txim siab seb lawv yuav cuam tshuam li cas nrog lwm cov molecules.

Raws li, qhov twg molecule yog amphipathic?

Cov roj thiab rog , uas nyob rau hauv science hu ua lipids , yog lub npe hu ua amphipathic molecules. Cov molecules no muaj ob qhov kawg rau lawv: dej-hlub ( hydrophilic ) sab thiab ntshai dej ( hydrophobic ) sab.

Yuav ua li cas amphipathic molecules tsim?

Cov amphiphilic xwm ntawm cov no molecules txhais txoj kev uas lawv daim ntawv daim nyias nyias. Lawv npaj lawv tus kheej rau hauv bilayers, los ntawm kev tso lawv cov polar pawg mus rau ib puag ncig cov dej nruab nrab, thiab lawv cov lipophilic chains ntawm sab hauv ntawm bilayer, txhais cov cheeb tsam uas tsis yog-polar ntawm ob lub polar.
