Feem ntau cov membrane phospholipids muaj glycerol (lecithin, phosphatidylcholine phosphatidylserine thiab cardiolipin). Sphingomyelin muaj sphingosine nraub qaum-pob txhahloov glycerol. … Txhua lub molecule yog tsim los ntawm ib lub glycerol molecule txuas rau ob fatty acids thiab ib pawg phosphate.
YPuas yog phosphatidylcholine yog sphingolipid?
Sphingomyelin feem ntau raug cais thiab tshaj tawm tias yog phospholipid tab sis nws yog tseem yog sphingolipid Zoo li phosphatidylcholine (lecithin), nws muaj choline moiety thiab phosphodiester linkage, tab sis nyob rau hauv sib piv rau phosphatidylcholine uas yog glycerollipid, lub caj qaum (lipid moiety) ntawm sphingomyelin yog ib qho ceramide.
phosphatidylcholine muaj dab tsi?
yog dab tsi? Phosphatidylcholine (PC) yog a phospholipid txuas rau choline particle. Phospholipids muaj fatty acids, glycerol, thiab phosphorous. Cov phosphorous ib feem ntawm cov tshuaj phospholipid - cov lecithin - yog tsim los ntawm PC.
YPuas yog phosphatidylserine tib yam li phosphatidylcholine?
Hauv cov tsiaj, phosphatidylserine yog hloov pauv los ntawm phosphatidylethylamine los yog phosphatidylcholine los ntawm ib qho ntawm ob Ca2+-nyob ntawm lub taub hau-pab pawg kev sib pauv hauv cov endoplasmic reticulum. Ob qho tshuaj tiv thaiv xav tau cov tshuaj serine tab sis cov khoom lag luam ethanolamine lossis choline, raws li.
YPob phospholipids muaj sphingosine?
1 Phospholipids. PLs muaj fatty acids, thiab phosphate-muaj moiety txuas rau glycerol los yog (cov amino cawv) sphingosine- yog li ua rau cov tebchaw nrog cov rog-soluble thiab dej-soluble cheeb tsam uas yog ubiquitous hauv cell membranes.
