txheej txheem no, hu ua lipolysis, tshwm sim hauv the cytoplasm. Cov txiaj ntsig fatty acids yog oxidized los ntawm β-oxidation rau hauv acetyl CoA, uas yog siv los ntawm Krebs cycle. Cov glycerol uas tau tso tawm los ntawm triglycerides tom qab lipolysis ncaj qha nkag mus rau glycolysis txoj hauv kev raws li DHAP.
YPuas lipolysis tshwm sim hauv daim siab?
DGAT1 tau nthuav tawm ubiquitously, tab sis feem ntau yog nyob rau hauv cov hnyuv me, cov leeg nqaij thiab cov qog mammary, nrog cov qib qis hauv daim siab thiab cov ntaub so ntswg adipose; DGAT2 feem ntau qhia hauv daim siab thiab cov ntaub so ntswg adipose [40]. … Lipolysis tshwm sim feem ntau hauv cov ntaub so ntswg adipose.
lipolysis thiab lipogenesis tshwm sim nyob qhov twg?
Fat accumululation yog txiav txim los ntawm qhov sib npaug ntawm cov roj synthesis (lipogenesis) thiab rog tawg (lipolysis / fatty acid oxidation). Lipogenesis encompasses cov txheej txheem ntawm fatty acid synthesis thiab tom qab triglyceride synthesis, thiab yuav siv sij hawm qhov chaw nyob rau hauv ob lub siab thiab adipose ntaub so ntswg(Daim duab 1).
Puas lipolysis tshwm sim hauv cov leeg?
Nws pom tias lipolysis hauv cov leeg pob txha yog tswj hwm nyob rau hauv ib qho txawv dua li cov ntaub so ntswg adipose. Yog li, thaum lub sij hawm lub qhov ncauj loading, lipolysis tus nqi yog suppressed nyob rau hauv cov ntaub so ntswg rog tab sis tseem unchanged nyob rau hauv lub cev nqaij daim tawv nqaij (8).
YPuas lipolysis tshwm sim hauv cov ntaub so ntswg adipose?
Adipose cov ntaub so ntswg lipolysis yog cov txheej txheem catabolic uas ua rau tawg ntawm triglycerides khaws cia hauvcov rog rog thiab tso tawm fatty acids thiab glycerol. … Ib txoj kev lipolytic tshiab tau tshwm sim hauv tib neeg cov rog rog. Natriuretic peptides txhawb nqa lipolysis los ntawm txoj kev cGMP-nyob.
