Lipoproteins yog cov khoom tshwj xeeb ua los ntawm cov roj ntsha uas nyob ib puag ncig los ntawm ib txheej ntawm phospholipid moleculesPhospholipids yog cov roj molecules uas txuas nrog cov phosphorus-muaj pawg. Lawv txawv ntawm kev ua amphipathic, uas txhais tau hais tias lawv muaj ob qho tib si polar thiab tsis-polar xaus.
Dab tsi yog lipoproteins tsim los ntawm?
Lipoproteins yog cov khoom nyuaj uas muaj lub hauv paus hydrophobic core ntawm cov lipids tsis-polar, feem ntau cov roj cholesterol esters thiab triglycerides. Qhov no hydrophobic core yog nyob ib puag ncig los ntawm ib tug hydrophilic membrane uas muaj phospholipids, dawb cholesterol, thiab apolipoproteins (Daim duab 1).
Dab tsi lipoprotein nqa cov rog noj?
Cov lipoproteins loj muaj xws li: Chylomicrons - cov khoom loj uas nqa cov lipid noj.
Nyob rau hauv daim ntawv twg yog cov lipid noj zaub mov feem ntau pom?
Triglycerides yog hom lipids tseem ceeb hauv lub cev thiab hauv cov zaub mov. Ntau tshaj 95 feem pua ntawm cov lipids hauv kev noj zaub mov yog nyob rau hauv daim ntawv ntawm triglycerides, qee qhov pom muaj thiab qee qhov zais hauv cov khoom noj.
Cov rog hloov mus rau lipoproteins nyob qhov twg?
Lub siab hloov pauv cov zaub mov uas tsis tau hlawv rau hauv cov lipoproteins tsawg heev (VLDL) thiab zais lawv rau hauv cov ntshav uas lawv hloov mus rau nruab nrab ntom lipoproteins (IDL), uas tom qab ntawd hloov dua siab tshiab mus rau low-density lipoprotein (LDL) particles thiab non-esterified fatty acids, uas tuaj yeem cuam tshuam rau lwm lub cev …
