7. Qhov twg hauv qab no tsim succinyl co-A? Kev piav qhia: Isoleucine, methionine, threonine thiab valine tsim succinyl co-A. Kev piav qhia: Plaub carbon atoms ntawm phenylalanine thiab tyrosine ua rau fumarate.
Qhov twg ntawm cov amino acids hauv qab no tsim Succinyl CoA?
Cov pob txha pob txha ntawm methionine, isoleucine, threonine, thiab valineyog degraded los ntawm txoj kev uas tawm los succinyl-CoA (Fig. 17-30), ib nrab ntawm cov citric acid. cycle.
Qhov twg ntawm cov amino acids hauv qab no yog ketogenic?
Lysine thiab leucine yog tib cov ketogenic amino acids nkaus xwb, vim lawv tau degraded rau hauv cov precursors rau ketone lub cev synthesis, acetyl-CoA thiab acetoacetate.
Qhov twg ntawm cov amino acids hauv qab no yog nruj me ntsis ketogenic thiab tsim acetyl CoA?
Txhua cov amino acids, tshwj tsis yog leucine thiab lysine, yog glucogenic, txhais tau tias lawv tuaj yeem siv C pob txha pob txha rau cov piam thaj synthesis. Leucine thiab lysine yog nruj me ntsis ketogenic amino acids (cov ntaub ntawv ketone lub cev) thiab tuaj yeem muab acetyl CoA los ua lub zog.
Qhov twg ntawm cov amino acids hauv qab no yog ob qho tib si glucogenic thiab ketogenic?
Isoleucine, phenylalanine, tryptophan, thiab tyrosineyog ob qho tib si ketogenic thiab glucogenic.
