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.

Puas yog cov dab dab dab dab dab dab dab dab dab dab dab dab?
Myth: Ib tug dab tshos tsis yog neeg ncaj ncees yog tiasnws haum yog. Fact: Tu siab, qhov no yog ib lo lus tsis tseeb uas tau raug perpetuated los ntawm aversive trainers. Txawm hais tias haum rau lub caj dab kom zoo khawb rau hauv cov tawv nqaij rhiab nyob ib ncig ntawm lub caj dab, uas ua rau muaj kev puas tsuaj loj rau cov thyroid, esophagus, thiab trachea.
Dab tsi yog txheej txheej txheej txheem nyob rau hauv lub ntiaj teb?
Lub neej muaj txheej txheem ntawm lub ntiaj teb yog the Biosphere. Lub neej muaj dabtsi? Cov kabmob lub neej yog qhov tseem ceeb ntawm lub sijhawm ntev ntawm cov kabmob tuaj yeem xav tau ua raws li qhov xav tau hauv kev ua haujlwm ua ntej tau teev tseg.
Cov txheej txheem huab cua twg muaj txheej txheej ozone?
Feem ntau atmospheric ozone yog concentrated nyob rau hauv ib txheej nyob rau hauv the stratosphere, li ntawm 9 txog 18 mais (15 mus rau 30 km) saum lub ntiaj teb nto (saib daim duab hauv qab). Ozone yog ib qho molecule uas muaj peb lub atoms oxygen.
Dab tsi yog qhov txheej txheem ntawm kev ua ntawm cov tshuaj tua kab mob?
Antipyretics ua rau lub hypothalamus override prostaglandin-induced nyob rau hauv kub. Lub cev tom qab ntawd ua haujlwm kom txo qhov kub thiab txias, uas ua rau txo qhov kub taub hau. Cov tshuaj tua kab mob feem ntau muaj lwm lub hom phiaj. Yuav ua li cas yog qhov kev txiav txim ntawm cov tshuaj tua kab mob?
Rau cov txheej txheem lossis cov txheej txheem?
Cov txheej txheem yog feem ntau yog ntau lub npe hais txog cov qauv uas tuaj yeem txiav txim siab. Nws cov lus yog cov qauv, tab sis cov pov thawj qhia tau tias cov txheej txheem feem ntau raug siv los ua cov lus thiab ntau ntau, zoo li cov ntaub ntawv thiab cov txheej txheem thiab lawv cov lus siv tsawg dua cov ntaub ntawv thiab cov txheej txheem.
