Txhais: Sphingolipids yog chav kawm ntawm lipid tau los ntawm aliphatic amino cawv sphingosine. Muaj peb leeg hom tseem ceeb ntawm sphingolipids : ceramides, phosphosphingolipids (sphingomyelins), thiab glycosphingolipids, uas txawv nyob rau hauv lub substituents ntawm lawv lub taub hau pab pawg neeg.
Ntxiv mus, dab tsi yog sphingolipids tsim los ntawm?
Cov sphingolipids , zoo li phospholipids, yog muaj li ntawm ib tug polar taub hau pab pawg neeg thiab ob nonpolar tails. Cov tub ntxhais ntawm sphingolipids yog cov saw ntev amino cawv, sphingosine. Cov sphingolipids cov tsos mob suav nrog sphingomyelins thiab glycosphingolipids (cerebrosides, sulfatides, globosides thiab gangliosides).
Qhov thib ob, ua li cas koj lub npe sphingolipids? Lub npe ntawm Sphingolipids Cov ntawv luv yog d18: 1. Thawj tus lej sawv cev rau cov pa roj carbon atoms. Tus lej thib ob yog tus lej ntawm ob daim ntawv cog lus. Hauv qhov no, tsab ntawv 'd' yog hais txog 2 (di-) hydroxyl pawg.
Tsis tas li ntawd, sphingolipids siv rau dab tsi?
Functions ntawm mammalian sphingolipids Sphingolipids feem ntau ntseeg tias tiv thaiv lub xov tooj ntawm tes tiv thaiv teeb meem ib puag ncig ib puag ncig los ntawm kev tsim cov tshuab ruaj khov thiab tiv taus cov txheej txheem txheej sab nrauv ntawm cov ntshav ntshav lipid bilayer.
Dab tsi yog kev ua haujlwm lom ntawm sphingomyelin?
Sphingomyelin muaj lub luag haujlwm tseem ceeb hauv cov qauv thiab kev ua haujlwm ntawm tes . Nws yog ib qho ntshav ntshav membrane tivthaiv thiab koom nyob rau hauv ntau yam signaling pathways. Cov metabolism hauv sphingomyelin tsim ntau yam khoom uas ua si lub luag haujlwm tseem ceeb hauv cov ntawm tes.

Lub hom phiaj ntawm cov roj raus dej uas siv nrog 100x lub hom phiaj xeem ntawv yog dab tsi?
Hauv lub tshuab tsom me me, kev tso roj yog txheej txheem siv txhawm rau txhawm rau daws qhov teeb meem ntawm lub tsom iav. Qhov no yog ua tiav los ntawm kev raus ob lub hom phiaj tsom iav thiab cov hnoos qeev hauv cov roj pob tshab ntawm qhov ntsuas siab refractive, yog li ua kom cov zauv zauv ntawm lub hom phiaj tsom iav
Kev sib raug zoo ntawm kev loj hlob ntawm tes thiab kev tsim tawm ntawm tes yog dab tsi?

Ib feem kawg ntawm cov txheej txheem ntawm kev tsim cov cell yog faib cell, thaum tus ntxhais lub cev lub cev sib cais los ntawm niam txiv ntawm tes
