Lipoproteins yog macromolecular complexes ntawm lipids thiab cov proteins uas tshwm sim los ntawm lub siab thiab hnyuvthiab koom nrog hauv kev thauj thiab rov faib cov lipids hauv lub cev.
Yuav ua li cas lipoprotein nyob rau hauv txoj hnyuv?
Chylomicrons yog cov chav kawm loj tshaj plaws thiab muaj zog tshaj plaws ntawm lipoprotein. Cov protein tseem ceeb yog apo B-48 tab sis lawv kuj muaj apo A-I, apo A-II thiab apo A-IV. Tom qab tso tawm, lawv tau txais apo E thiab apo C los ntawm HDL. Chylomicrons yog tsim nyob rau hauv txoj hnyuv thiab yog lub tsheb thauj mus rau kev noj haus rog.
YPuas yog lipoprotein tsim los ntawm apolipoprotein?
Apolipoproteins yog cov protein uas khi lipids (cov roj-soluble tshuaj xws li rog thiab roj cholesterol) los tsim cov lipoproteins. Lawv thauj cov lipids (thiab cov vitamins uas muaj roj soluble) hauv cov ntshav, cov kua cerebrospinal thiab lymph. Cov lipid Cheebtsam ntawm lipoproteins yog insoluble hauv dej.
YPuas yog lipoproteins tsim hauv lub cev?
Lawv yog ua hauv plab hnyuvthiab yog li cuam tshuam los ntawm yam koj noj. Tsawg-density lipoprotein (VLDL) cov khoom kuj tseem nqa triglycerides rau cov ntaub so ntswg. Tab sis lawv yog ua los ntawm lub siab.
Lub hauv paus ntawm lipoproteins yog dab tsi?
Lipoproteins yog synthesized nyob rau hauv lub siabthiab lawv tau txais lawv daim ntawv mature tom qab kev cuam tshuam nrog enzymes uas muaj nyob rau hauv txoj kev. Lipoprotein-derived fatty acids yog tso tawm los ntawm lipoprotein lipase thiabTom qab ntawd raug coj los ntawm cardiomyocytes los yog dhau los ntawm fatty acid receptors, xws li CD36.
