Qhov sib txawv tseem ceeb ntawm leucine thiab isoleucine yog tias leucine synthesis koom nrog ib qho nruab nrab hu ua alpha-ketoisovaleric acid thaum lub isoleucine synthesis suav nrog ib qho nruab nrab hu ua alpha-ketoglutaric acid. Tsis tas li ntawd, ob leeg sib txawv hauv lawv txoj haujlwm ib yam nkaus.
Amino acids yog lub tsev tsim cov proteins. Lawv sib txawv raws li cov pab pawg sib txawv uas txuas rau chimeric carbon atom. Tsis tas li ntawd, muaj tag nrho ntawm 20 txawv amino acids. Ntawm lawv, qee qhov tseem ceeb amino acids uas peb yuav tsum tau noj los ntawm kev noj haus. Tsis tas li ntawd, muaj peb ceg saw hlau amino acids, uas yog qhov tseem ceeb. Lawv yog valine, isoleucine thiab leucine. Leucine thiab Isoleucine yog isomers ntawm ib leeg. Leucine thiab isoleucine synthesis tshwm sim ntawm pyruvic acid synthesis. Txawm li cas los xij, qhov xav tau ntawm cov neeg nruab nrab hauv cov no txawv.
Leucine yog dab tsi?
Leucine (daim ntawv luv - Leu) yog ib qho tseem ceeb amino acid. Nws yog ib qho tsis muaj polar, uncharged amino acid. Yog li ntawd, peb yuav tsum suav nrog nws hauv kev noj haus. Nqaij, cov khoom noj siv mis thiab cov khoom soy yog nplua nuj nyob rau hauv leucine. Leucine yog ib tug branched saw alpha - amino acid. Raws li tib neeg tsis muaj cov enzyme xav tau rau leucine synthesis, lawv tsis tuaj yeem tsim cov leucine. Txawm li cas los xij, cov nroj tsuag thiab cov kab mob tuaj yeem tsim cov leucine los ntawm pyruvic acid txij li qhov nruab nrab alpha-ketoisovaleric acid muaj nyob hauv lawv.
Daim duab 01: Leucine
Y Nyob rau hauv tib neeg, leucine metabolism tshwm sim hauv daim siab, cov ntaub so ntswg adipose thiab cov leeg nqaij. Cov khoom kawg ntawm leucine metabolism yog acetoacetate thiab acetic acid. Yog li, leucine categorizes raws li ketogenic amino acid. Tsis tas li ntawd, kev ua haujlwm ntawm leucine hauv tib neeg muaj xws li kev loj hlob thiab kho cov leeg, tsim cov tshuaj hormones loj hlob thiab kev tswj hwm lub zog. Tsis tas li, leucine tau muab los ua kev kho mob rau phenylketonuria.
Isoleucine yog dab tsi?
Isoleucine (luv luv - Ile) yog isomer ntawm leucine. Nws tseem yog ib qho tseem ceeb amino acid. Yog li ntawd, tib neeg lub cev tsis tuaj yeem tsim cov isoleucine. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau noj cov khoom noj. Cov khoom noj uas muaj isoleucine muaj xws li qe, nqaij thiab cov khoom soy.
Ntxiv mus, isoleucine yog cov saw saw amino acid ua ke hauv cov nroj tsuag thiab microbes. Zoo ib yam li leucine, isoleucine synthesis tshwm sim thaum lub sij hawm pyruvic acid synthesis pathway. Qhov nruab nrab cuam tshuam yog alpha-ketoglutarate. Cov khoom kawg ntawm isoleucine metabolism hauv tib neeg tsim Succinyl-CoA thiab oxaloacetate. Yog li ntawd, nws belongs rau ob pawg ketogenic thiab glucogenic.
Daim duab 02: Isoleucine
Isoleucine muaj ntau lub luag haujlwm hauv tib neeg lub cev. Lawv suav nrog kev pab kho qhov txhab, detoxification ntawm nitrogenous pov tseg, stimulation ntawm lub cev tsis muaj zog thiab tswj kev tso tawm ntawm qee cov tshuaj hormones, thiab lwm yam.
Dab tsi yog qhov zoo sib xws ntawm Leucine thiab Isoleucine?
- Leucine thiab Isoleucine yog qhov tseem ceeb amino acids.
- Yog li ntawd, tib neeg lub cev tsis tuaj yeem tsim cov amino acids.
- Txawm li cas los xij, cov nroj tsuag thiab microbes tuaj yeem ua ke ob qho tib si.
- Ntxiv mus, lawv ob leeg muaj ceg saw amino acids.
- Kuj, ob qho tib si tsis yog-polar, tsis muaj cov amino acids.
- Leucine thiab Isoleucine tuaj yeem tau los ntawm nqaij, khoom noj siv mis thiab qe.
- Pyruvic acid synthesis txoj hauv kev ua rau ob qho tib si amino acids.
Qhov txawv ntawm Leucine thiab Isoleucine yog dab tsi?
Leucine thiab isoleucine yog ob ceg-chain tseem ceeb amino acids. Qhov tseem ceeb, lsoleucine yog isomer ntawm leucine. Lawv synthesis ntawm pyruvic acid synthesis. Qhov sib txawv tseem ceeb ntawm leucine thiab isoleucine yog qhov nruab nrab lawv xav tau thaum lub sijhawm sib xyaw. Leucine xav tau alpha-ketoisovaleric acid thaum isoleucine xav tau alpha-ketoglutaric acid. Tsis tas li ntawd, tseem muaj lwm qhov sib txawv ntawm leucine thiab isoleucine raws li cov haujlwm uas lawv ua. Leucine koom nrog hauv kev loj hlob thiab kho cov leeg, tsim cov tshuaj hormones loj hlob, thiab kev tswj hwm lub zog. Thaum cov isoleucine koom nrog hauv kev kho qhov txhab, tshem tawm cov tshuaj nitrogen hauv cov pov tseg, simulation ntawm lub cev tsis muaj zog, thiab tswj kev tso tawm ntawm qee cov tshuaj hormones.
Cov hauv qab no qhia txog qhov sib txawv ntawm leucine thiab isoleucine hauv daim ntawv teev npe.
Summary – Leucine vs Isoleucine
Leucine thiab isoleucine yog qhov tseem ceeb, ceg saw amino acids uas yuav tsum tau noj los ntawm pluas noj. Ob leeg yog tsim thaum lub sij hawm pyruvic acid txoj kev, tab sis qhov sib txawv tseem ceeb ntawm leucine thiab isoleucine nyob rau hauv hom intermediates lawv xav tau rau cov synthesis. Leucine xav tau alpha - ketoisovaleric acid thaum isoleucine xav tau alpha-ketoglutaric acid. Ntxiv mus, lawv lub luag haujlwm physiological kuj txawv. Leucine koom nrog hauv kev loj hlob thiab kho cov leeg nqaij thaum isoleucine koom nrog hauv cov txheej txheem kho qhov txhab thiab tshem tawm detoxification. Qhov no yog qhov txawv ntawm leucine thiab isoleucine.
