Lipogenesis yog txhawb nqa los ntawm kev noj zaub mov carbohydrate siab, thaum nws yog inhibited los ntawm polyunsaturated fatty acids thiab yoo mov. Cov teebmeem no yog ib feem kho los ntawm cov tshuaj hormones, uas inhibit (kev loj hlob hormone, leptin) lossis txhawb nqa (insulin) lipogenesis.
YYuav pib lipogenesis dab tsi?
Lipogenesis yog cov txheej txheem cuam tshuam nrog kev sib txuas ntawm fatty acids lossis triglycerides, uas yog tswj hwm thiab tswj los ntawm ntau yam hauv lub cev. Cov txheej txheem yog txhawb nqa los ntawm noj zaub mov ntau hauv carbohydrates thiab ntau cov tshuaj hormones hauv lub cev, xws li insulin, kho cov txheej txheem.
Yuav ua li cas enzyme koom nrog hauv kev tswj hwm lipogenesis?
Enzymes lub hauv paus rau cov txheej txheem ntawm lipogenesis yog cov uas catalyze fatty acid biosynthesis: acetyl-coenzyme A carboxylase (ACC); fatty acid synthase; thiab ATP-citrate lyase, uas ua lub luag haujlwm hauv kev hloov pauv ntawm acetyl-coenzyme A (acetyl-CoA) los ntawm mitochondrion mus rau cytosol, qhov twg fatty acid synthesis tshwm sim (…
Cov tshuaj hormone twg inhibit lipolysis thiab txhawb lipogenesis?
Glucagon kuj ua raws li cov tshuaj lipolytic uas txhawb kev tawg ntawm triglycerides los ntawm cov lipid droplets [63]. Insulin tawm dag zog tawm tsam, txhawb adipogenesis thiab inhibiting lipolysis [64].
Vim li cas insulin txhawb lipogenesis?
Insulin txhawb nqa lipogenesis los ntawm kev ua kom cov piam thaj nkag, tswj cov qib ntawm glycerol-3-P thiab lipoproteinlipase (LPL).

Lub sijhawm ua xua yam tshuaj hormone secreted yog?
Adrenaline yog cov tshuaj hormones ntuj tso tawm los teb rau kev ntxhov siab. Thaum txhaj tshuaj, adrenaline sai thim rov qab cov teebmeem ntawm anaphylaxis los ntawm kev txo qis caj pas o, qhib txoj hlab pa, thiab tswj lub plawv ua haujlwm thiab ntshav siab.
Puas yog cov tshuaj hormone secreted los ntawm lub plawv thiab txhawb natriuresis?
Atrial natriuretic peptide (ANP) lossis atrial natriuretic factor (ANF) yog natriuretic peptide hormone secreted los ntawm lub plawv atria uas nyob rau hauv tib neeg yog encoded los ntawm NPPA noob. Yuav ua li cas cov tshuaj hormones secreted los ntawm lub plawv?
Yam tshuaj hormone twg yog thyroxine?
Thyroxine yog tseem ceeb cov tshuaj hormone tso rau hauv cov hlab ntsha los ntawm cov thyroid caj pas. Nws ua lub luag haujlwm tseem ceeb hauv kev zom zaub mov, lub plawv thiab cov leeg ua haujlwm, lub hlwb kev loj hlob thiab kev saib xyuas cov pob txha.
Yam tshuaj hormone twg ua rau bph?
Prostatic o nyob ntawm lub zog androgen dihydrotestosterone (DHT). Nyob rau hauv lub caj pas prostate, hom II 5-alpha-reductase metabolizes circulating testosterone rau hauv DHT, uas ua hauj lwm hauv zos, tsis systemically. DHT khi rau androgen receptors nyob rau hauv lub cell nuclei, uas yuav ua rau BPH.
Puas yog kev txhawb nqa thiab kev txhawb siab tib yam?
Buoyancy (/ˈbɔɪənsi, ˈbuːjənsi/), los yog upthrust, yog ib zog nce siab los ntawm cov kua dej uas tawm tsam qhov hnyav ntawm ib feem lossis tag nrho cov khoom immersed. Nyob rau hauv ib kem ntawm cov kua, siab nce nrog qhov tob raws li qhov hnyav ntawm cov kua dej ntau dhau.
