Lipogenesis yog hloov pauv ntawm fatty acid thiab glycerol rau hauv cov rog LOSSIS cov txheej txheem metabolic los ntawm cov acetyl-CoA hloov mus rau triglyceride rau khaws cia hauv cov rog. … Fatty acids yog tsim nyob rau hauv lub cytoplasm ntawm hlwb los ntawm rov ntxiv ob-carbon units rau acetyl-CoA.
Dab tsi yog cov kauj ruam ntawm lipogenesis?
Cov kauj ruam hauv lipogenesis
thawj kauj ruam rau xws li fatty acid synthesis yog acetyl-CoA carboxylation rau malonyl-CoA nrog kev pab ntawm enzyme acetyl-CoA carboxylase, uas feem ntau tshwm sim hauv daim siab hlwb, tab sis kuj nyob rau hauv cov leeg pob txha thiab cov ntaub so ntswg adipose.
cov txheej txheem ntawm lipogenesis tshwm sim nyob qhov twg?
txheej txheem no, hu ua lipogenesis, tsim cov lipids (rog) los ntawm acetyl CoA thiab siv qhov chaw hauv cytoplasm ntawm adipocytes (fat cells) thiab hepatocytes (siab hlwb). Thaum koj noj ntau cov piam thaj lossis carbohydrates ntau dua li koj lub cev xav tau, koj lub cev siv acetyl CoA los hloov cov rog dhau mus.
Dab tsi yog lipogenesis Cov txheej txheem no tseem ceeb npaum li cas?
Lipogenesis yog txheej txheem koj lub cev siv los hloov cov carbohydrates rau hauv cov roj fatty acids, uas yog cov tsim cov rog. Rog yog ib txoj hauv kev zoo rau koj lub cev kom khaws lub zog. Kawm txog qhov tseem ceeb ntawm acetyl-CoA thiab insulin hauv lipogenesis.
piv txwv lipogenesis yog dab tsi?
Hauv kev sib txuas ntawm triglyceride, peb cov roj fatty acids yog esterified rau glycerol hauv endoplasmic reticulum. Cov hlwb uas ua lipogenesis feem ntau yog adipocytes thiab liver hlwb. Cov kab mob siab, txawm li cas los xij, tso tawm triglycerides hauv daim ntawv ntawm lipoproteins tsawg-density lipoproteins (VLDL) rau hauv cov hlab ntsha.
