Acetyl - CoA yog ib qho tseem ceeb biochemical molecule nyob rau hauv cellular ua pa . Nws yog ua nyob rau hauv lub thib ob kauj ruam ntawm aerobic ua pa Tom qab glycolysis thiab nqa cov pa roj carbon atoms acetyl pab pawg rau TCA lub voj voog kom oxidized rau kev tsim hluav taws xob.

Hais txog qhov no, acetyl CoA siv rau dab tsi?

Acetyl coenzyme A, los yog zoo dua lub npe acetyl - CoA , yog ib qho tseem ceeb molecule siv hauv cov txheej txheem metabolic. Nws yog qhov tseem ceeb siv los ntawm lub cev rau lub zog tsim los ntawm lub voj voog citric acid, lossis Krebs cycle.

Kuj Paub, vim li cas pyruvate yuav tsum tau hloov mus rau acetyl CoA? Hauv hloov dua siab tshiab ntawm pyruvate ua rau acetyl CoA , cwb pyruvate ua molecule poob ib qho atom nrog kev tso tawm carbon dioxide. Thaum lub sij hawm tawg ntawm pyruvate ua , electrons yog pauv rau NAD + los tsim NADH, uas yuav siv los ntawm tes los tsim ATP.

Tsis tas li ntawd, ua li cas rau acetyl coenzyme A thaum ua pa?

Acetyl Coenzyme Kev Tsim Hauv cov txheej txheem, txhua pyruvic acid molecule poob ib carbon atom, uas ua ke nrog muaj oxygen los tsim carbon dioxide, uas yog tso tawm los ntawm exhaling. Nicotinamide adenine dinucleotide, los yog NAD, kuj nqa tawm hydrogen hauv cov txheej txheem ntawm oxidation, ua NADH.

Acetyl CoA ua li cas?

Acetyl - CoA yog tsim Los ntawm kev tawg ntawm ob qho tib si carbohydrates (los ntawm glycolysis) thiab lipids (los ntawm β-oxidation). Tom qab ntawd nws nkag mus rau lub voj voog citric acid hauv mitochondrion los ntawm kev sib txuas nrog oxaloacetate rau daim ntawv citrate.
