Phospholipid Bilayer. Cov phospholipid bilayer muaj ob txheej ntawm phospholipids , nrog ib tug hydrophobic, los yog dej-ntxhais, sab hauv thiab ib tug hydrophilic, los yog dej-hlub, sab nrauv. Cov hydrophobic fatty acids taw tes rau nruab nrab ntawm cov plasma membrane, thiab lub taub hau hydrophilic taw tes rau sab nraud.

Kuj paub, vim li cas phospholipids tsim ob txheej?

Thaum cellular daim nyias nyias daim ntawv , phospholipids sib dhos rau hauv ob txheej vim hais tias ntawm no hydrophilic thiab hydrophobic zog. Cov phosphate taub hau hauv txhua qhov txheej fim lub aqueous los yog watery ib puag ncig ntawm ob sab, thiab cov tails nkaum deb ntawm cov dej ntawm lub txheej ntawm lub taub hau, vim lawv yog hydrophobic.

Tsis tas li ntawd, phospholipids cuam tshuam nrog ib leeg li cas? Yog li, thaum ob peb phospholipids los yog glycolipids tuaj ua ke nyob rau hauv ib tug aqueous tov, hydrophobic tails sib tham sib los tsim ib lub chaw hydrophobic, thaum lub taub hau hydrophilic sib tham sib los ntawm kev tsim hydrophilic txheej rau txhua sab ntawm lub bilayer taw tes radically mus rau lub polar hnyav.

Ib sab saum toj no, phospholipid bilayer taw qhia li cas?

Cov phospholipids nyob rau hauv lub plasma membrane yog teem nyob rau hauv ob txheej, hu ua a phospholipid bilayer . Cov dej-ntxhais tails yog nyob rau sab hauv ntawm daim nyias nyias, whereas cov dej-hlub taub hau taw tawm sab nraud, mus rau cytoplasm lossis cov kua dej uas nyob ib puag ncig ntawm tes.

phospholipids tsim li cas?

2 Phospholipids . Phospholipids feem ntau yog tsim los ntawm glycerides los ntawm kev hloov ib qho ntawm peb fatty acids los ntawm ib pab pawg phosphate nrog rau lwm cov molecule txuas rau nws kawg. Lwm tus daim ntawv ntawm phospholipids yog sphingomyelin, uas yog muab los ntawm sphingosine es tsis txhob ntawm glycerol.
