Qhov sib txawv tseem ceeb ntawm glucogenic thiab ketogenic amino acids yog tias glucogenic amino acids tsim pyruvate lossis lwm yam qabzib ua ntej thaum lawv catabolism thaum ketogenic amino acids tsim acetyl CoA thiab acetoacetyl CoA thaum lawv catabolism.
Amino acids yog lub hauv paus molecules, uas ua rau cov qauv tshuaj ntawm cov proteins thiab polypeptides. Txawm hais tias muaj ntau yam kev faib tawm rau cov amino acids, peb tuaj yeem faib lawv li glucogenic thiab ketogenic amino acids nyob ntawm qhov nruab nrab uas lawv tsim thaum lawv catabolism. Raws li tau hais los saum no, cov khoom kawg ntawm catabolism ntawm cov amino acids muab ob hom khoom nruab nrab; pyruvate (los yog lwm yam qabzib precursors) los yog acetyl CoA thiab acetoacetyl CoA.
YGlucogenic Amino Acids yog dab tsi?
Glucogenic amino acids yog chav kawm ntawm cov amino acids uas tsim pyruvate lossis lwm yam qabzib precursors thaum catabolism ntawm cov amino acid. Cov molecules no hloov mus rau cov piam thaj los ntawm gluconeogenesis. Tsis tas li ntawd, cov khoom nruab nrab ntawm cov amino acids no tuaj yeem suav nrog pyruvate, alpha-ketoglutarate, succinyl CoA, fumarate lossis oxaloacetate.
Daim duab 01: Cov Amino Acids sib txawv hauv cov txheej txheem Amino Acid Catabolism
Ntxiv mus, yuav luag txhua qhov tseem ceeb thiab tsis tseem ceeb amino acids yog glucogenic amino acids tshwj tsis yog rau lysine thiab leucine.
Qee yam piv txwv rau cov amino acids no yog raws li hauv qab no:
- Alanine
- Arginine
- Asparagine
- Aspartic
- YCysteine
- YGlutamic
- YGlutamine
- YGlycine
- Histidine
- Methionine
- Proline
- Serine
- Valine
Ketogenic Amino Acids yog dab tsi?
Ketogenic amino acids yog cov chav kawm ntawm cov amino acids uas tsim acetyl CoA thiab acetoacetyl CoA thaum lub sij hawm catabolism ntawm cov amino acid. Cov no yog cov khoom nruab nrab ntawm lawv cov catabolism. Tsis tas li ntawd, cov khoom no tuaj yeem hloov mus rau hauv ketone lub cev. Txawm li cas los xij, tsis zoo li glucogenic amino acids, cov amino acids tsis tuaj yeem tsim cov piam thaj. Vim hais tias, lub cev ketone uas lawv tsim degrades rau carbon dioxide nyob rau hauv lub citric acid voj voog thaum kawg.
Daim duab 02: Lysine
Cov ketogenic amino acids ntau tshaj plaws hauv peb lub cev yog lysine thiab leucine, uas yog cov amino acids tseem ceeb rau peb. Ntxiv mus, muaj qee cov amino acids uas tuaj yeem ua raws li ob qho tib si glucogenic lossis ketogenic cov ntaub ntawv.
tsib lub amino acids loj uas tuaj yeem ua rau ob lub luag haujlwm no yog raws li hauv qab no:
- Phenylalanine
- Isoleucine
- Threonine
- Tryptophan
- YTyrosine
Tsis tas li, cov tsib cov amino acids no tuaj yeem ua rau cov piam thaj ua ntej (lub luag haujlwm ntawm glucogenic amino acids) thiab rau fatty acid precursors (lub luag haujlwm ntawm ketogenic amino acids). Tsis tas li ntawd, peb lub cev siv cov ketogenic amino acids los tsim cov lipids lossis rau ketogenesis.
Qhov txawv ntawm Glucogenic thiab Ketogenic Amino Acids yog dab tsi?
Glucogenic amino acids yog cov chav kawm ntawm cov amino acids uas tsim pyruvate los yog lwm yam qabzib precursors thaum lub sij hawm catabolism ntawm cov amino acid whereas ketogenic amino acids yog cov chav kawm ntawm cov amino acids uas tsim acetyl CoA thiab acetoacetyl CoA thaum lub sij hawm catabolism ntawm cov amino acids. amino acid. Ob chav kawm ntawm cov amino acids no txawv ntawm ib leeg raws li cov khoom nruab nrab uas lawv tsim thaum lawv catabolism. Yog li qhov sib txawv tseem ceeb ntawm glucogenic thiab ketogenic amino acids yog tias glucogenic amino acids tsim pyruvate lossis lwm yam qabzib precursors thaum lawv catabolism thaum ketogenic amino acids tsim acetyl CoA thiab acetoacetyl CoA thaum lawv catabolism.
Lwm qhov txawv ntawm glucogenic thiab ketogenic amino acids yog tias cov glucogenic amino acids koom nrog hauv kev tsim cov piam thaj thaum cov ketogenic amino acids tsis tuaj yeem tsim cov piam thaj.
Cov duab hauv qab no qhia txog qhov sib txawv ntawm glucogenic thiab ketogenic amino acids hauv daim ntawv.
Summary - Glucogenic vs Ketogenic Amino Acids
Amino acids yog lub tsev tsim cov proteins. Tsis tas li ntawd, muaj ob hom amino acids nyob ntawm cov khoom nruab nrab uas lawv tsim thaum lawv catabolism. Lawv yog glucogenic thiab ketogenic amino acids. Qhov sib txawv tseem ceeb ntawm glucogenic thiab ketogenic amino acids yog tias glucogenic amino acids tsim pyruvate lossis lwm yam qabzib precursors thaum lawv catabolism thaum ketogenic amino acids tsim acetyl CoA thiab acetoacetyl CoA thaum lawv catabolism.
