Qhov sib txawv tseem ceeb ntawm glycolipids thiab phospholipids yog tias glycolipids muaj pawg carbohydrate txuas rau lipid residue, whereas phospholipids muaj phosphate pawg txuas nrog lipid residue.
Glycolipids thiab phospholipids yog ob hom lipid-muaj tshuaj uas peb tuaj yeem pom hauv cov cell membranes. Lawv txawv ntawm ib leeg raws li cov qauv tshuaj thiab kev ua haujlwm. Txawm li cas los xij, ob qho tib si no muaj cov lipid residues.
YGlycolipids yog dab tsi?
Glycolipids yog lipids uas muaj carbohydrates. Ntawm no, lipid thiab carbohydrate tau txuas rau ib leeg los ntawm glycosidic daim ntawv cog lus, uas yog hom kev sib cog lus. Cov carbohydrate hauv cov qauv glycolipid tuaj yeem yog monosaccharide lossis oligosaccharide. Feem ntau cov lipid residues tuaj yeem tsim glycolipids yog glycerolipids, thiab sphingolipids. Lawv muaj glycerol thiab sphingosine raws li lawv cov pob txha, feem. Fatty acids tau txuas rau cov pob txha no.
Cov lipid residue muaj ob ntu: pawg taub hau polar thiab pawg tsis muaj polar. Nyob rau hauv ib lub cell membrane, sab nrauv ntawm daim nyias nyias yog ua los ntawm polar taub hau pawg, thaum sab hauv yog ua los ntawm nonpolar tail pawg. Cov saccharides txuas mus rau lub cell membrane los ntawm pawg polar taub hau. Qhov no ligand tivthaiv kuj yog polar; Yog li, nws tso cai rau glycolipid soluble nyob rau hauv aqueous ib ncig ntawm lub cell.
Daim duab 01: Subtypes ntawm Glycolipids
Thaum tsim cov glycolipid, cov piam thaj molecule khi nrog ib pawg dawb hydroxyl ntawm cov lipid residue nyob rau hauv cov pob txha los ntawm cov anomeric carbon ntawm cov suab thaj. Ib daim ntawv cog lus glycosidic tsim ntawm cov anomeric carbon ntawm qab zib molecule thiab pawg hydroxyl ntawm lipid. Muaj ntau hom glycolipids xws li glyceroglycolipids thiab glycosphingolipids
Phospholipids yog dab tsi?
Phospholipids yog lipid residues uas muaj phosphate pawg. Cov no yog cov feem ntau lipid Cheebtsam nyob rau hauv lub hlwb thiab lawv tsuas yog ua raws li cov qauv. Peb tuaj yeem pom cov khoom no hauv cov qauv bio-membrane xws li lysosomal membrane, mitochondrial membrane, endoplasmic reticulum membrane, thiab Golgi apparatus membrane.
Daim duab 02: Cov qauv ntawm cov Cell Membrane
Phospholipids yog cov tshuaj amphipathic uas muaj lub ncov qaumteb qabteb, lub taub hau hydrophilic thiab ob lub hydrophobic, tsis muaj polar tails. Nyob rau hauv lub cell membrane, muaj ib tug bilayer ntawm phospholipids (ob txheej ntawm phospholipids). Lub taub hau qaum teb yog nyob rau sab nrauv thiab cov tails uas tsis muaj polar nyob nruab nrab ntawm ob txheej phospholipid.
Qhov txawv ntawm Glycolipids thiab Phospholipids yog dab tsi?
Qhov sib txawv tseem ceeb ntawm glycolipids thiab phospholipids yog tias glycolipids muaj pawg carbohydrate txuas rau lipid residue, hos phospholipids muaj phosphate pawg txuas nrog lipid residue. Yog li, glycolipids muaj cov carbohydrate moiety, thaum tsis muaj carbohydrate moieties hauv phospholipids. Hauv lwm lo lus, tsis muaj pawg phosphate ntxiv hauv cov qauv glycolipid, tab sis muaj phosphate pawg hauv phospholipid. Thaum txiav txim siab txog cov qauv tshuaj, glycolipid muaj lub taub hau hydrophilic thiab hydrophobic tail thaum phospholipids muaj lub taub hau hydrophilic thiab ob lub tails hydrophobic.
Cov lus qhia hauv qab no qhia txog qhov sib txawv ntawm glycolipids thiab phospholipids hauv daim ntawv teev npe.
Summary – Glycolipids vs Phospholipids
Glycolipids thiab phospholipids yog ob hom lipid-muaj tshuaj uas peb tuaj yeem pom hauv cov cell membranes. Qhov sib txawv tseem ceeb ntawm glycolipids thiab phospholipids yog tias glycolipids muaj ib pawg carbohydrate txuas rau lipid residue whereas phospholipids muaj phosphate pawg txuas nrog lipid residue.
