Qhov sib txawv tseem ceeb ntawm phospholipids thiab sphingolipids yog tias phospholipids yog cov lipids ntau tshaj plaws hauv bio-membranes suav nrog cov plasma membrane thaum sphingolipids yog cov lipids ntau tshaj plaws hauv cov ntaub so ntswg.
Lipid yog macromolecule tsim los ntawm glycerol thiab fatty acids. Lipids feem ntau yog ob hom xws li cov lipids yooj yim thiab cov lipids sib xyaw. Structurely, lipids yooj yim yog esters ntawm fatty acids nrog ntau yam cawv. Lawv suav nrog roj thiab roj. Cov lipids yog cov lipids uas tawm los ntawm fatty acids, cawv thiab lwm pab pawg ntxiv xws li phosphoric acid, nitrogenous base carbohydrates, sulfur, amino acids, proteins, thiab lwm yam.raws li hydrolysis. Ib yam li ntawd, Phospholipids thiab sphingolipids yog ob hom kev sib xyaw lipids, uas yog cov khoom siv. Tsis tas li ntawd, muaj lipids hu ua derived lipids. Cov no yog cov khoom siv hydrolytic ntawm cov lipids yooj yim thiab sib xyaw uas muaj cov yam ntxwv ntawm lub cev yog lipids.
Phospholipids yog dab tsi?
Phospholipids yog cov lipids ntau tshaj plaws uas ua haujlwm ntawm cov khoom siv bio-membranes nrog rau cov cell membrane, lysosomal membrane, mitochondrial membrane, endoplasmic reticulum membrane, Golgi apparatus membrane, thiab lwm yam. Tsis tas li ntawd, lawv yog amphipathic molecules muaj li ntawm polar. hydrophilic lub taub hau thiab ob qho tib si tsis-polar, hydrophobic tails.
Daim duab 01: Phospholipids
Thaum tsim cov phospholipid molecule, ib tug fatty acid tail tshem tawm thiab hloov nws nrog ib pab pawg neeg phosphate. Ua ke nrog cov glycerol molecule, phosphate pawg ua rau lub taub hau ntawm cov phospholipid molecule. Tsis tas li ntawd, muaj ib qho ntxiv molecule txuas rau ib pawg phosphate. Nws tuaj yeem yog choline molecule, pawg serine, lossis ethanolamine molecule. Yog li ntawd, raws li cov no, phospholipids yog peb hom xws li phosphoglycerides, phosphor inositides thiab phospho sphingosides.
Sphingolipids yog dab tsi?
Sphingolipids yog ib hom phospholipids uas muaj cov kab txuas ntev amino cawv hu ua sphingosine txuas rau cov roj ntsha fatty acid. Yog li ntawd, lub hauv paus ntawm sphingolipids yog sphingosine. Tsis tas li ntawd, cov no yog cov lipids feem ntau pom nyob rau hauv cov ntaub so ntswg uas cuam tshuam nrog lub teeb liab kis tau tus mob thiab kev paub ntawm tes.
Daim duab 02: Sphingolipids
Muaj peb pawg ntawm sphingolipids xws li sphingomyelin, glycosphingolipids thiab gangliosides. Sphingomyelins muaj ntau nyob rau hauv cov cell membranes ntawm cov tsiaj hlwb tshwj xeeb tshaj yog nyob rau hauv myelin sheath ntawm neurons. Ntawm qhov tod tes, glycosphingolipids yog ib hom conjugated lipids uas muaj nyob rau hauv lub hlwb thiab qaum qaum. Hom kawg, gangliosides yog cov sphingolipids nyuaj tshaj plaws uas tam sim no muaj ntau nyob rau hauv ganglion hlwb ntawm paj hlwb.
Dab tsi yog qhov zoo sib xws ntawm Phospholipids thiab Sphingolipids?
- Phospholipids thiab Sphingolipids yog lipids uas koom nrog ntau lub luag haujlwm hauv peb lub cev.
- Lawv ob leeg yog cov lipids sib xyaw uas muaj cov pab pawg ntxiv uas tsis yog fatty acids thiab glycerol molecules.
- Tsis tas li, ob qho tib si ua haujlwm ua cov txheej txheem ntawm daim nyias nyias thiab cov ntaub so ntswg.
- Tsis tas li ntawd, ob leeg muaj phosphate pawg hauv lawv cov molecules.
- Dhau li, ob qho tib si tsis sib xyaw nrog dej zoo.
Qhov txawv ntawm Phospholipids thiab Sphingolipids yog dab tsi?
Phospholipds thiab sphingolipids yog cov lipids sib txawv me ntsis ntawm ib leeg. Qhov sib txawv loj ntawm phospholipids thiab sphingolipids yog tias phospholipids yog cov khoom siv ntau tshaj plaws nyob rau hauv biomembranes thaum cov sphiongolipids feem ntau pom hauv cov ntaub so ntswg. Tsis tas li ntawd, sphingolipids muaj sphingosine ua lub hauv paus molecule thaum nws tsis nyob hauv phospholipids.
Cov ntawv qhia hauv qab no nthuav tawm qhov tseeb ntxiv ntawm qhov sib txawv ntawm phospholipids thiab sphingolipids.
Summary – Phospholipids vs Sphingolipids
Phospholipids yog cov lipids sib xyaw uas muaj ntau hauv cov ntshav plasma, thiab lawv tsim cov lipid bilayer. Ntawm qhov tod tes, sphingolipid yog ib hom phospholipids uas muaj ntau nyob rau hauv lub paj hlwb. Yog li ntawd, lawv koom nrog hauv cov teeb liab kis tau tus mob thiab kev paub ntawm tes. Ntxiv mus, sphingolipids muaj sphingosine ua lawv cov molecule tseem ceeb. Li no, qhov no qhia txog qhov sib txawv ntawm phospholipids thiab sphingolipids.
