L-valine CAS 72-18-4 Rau Cov Zaub Mov Qib (AJI USP)
Pab:
L-Valine (Abbreviated Val) yog ib qho ntawm 18 hom amino acids, thiab ib ntawm yim qhov tseem ceeb amino acids ntawm tib neeg lub cev. Nws yog hu ua branched saw amino acids (BCAA) nrog L-Leucine thiab L-Isoleucine ua ke vim tias lawv txhua tus muaj cov xov methyl sab saw hlau hauv lawv cov qauv molecular.
L-Valine yog ib qho ntawm aliphatic amino acids ntawm nees nkaum hom proteinogenic amino acids thiab tus ceg-amino-acid amino acids (BCAA) tias tus tsiaj nws tus kheej tsis tuaj yeem ua ke nws thiab yuav tsum tau noj los ntawm kev noj haus kom tau raws li lawv cov khoom noj khoom haus; yog li L-valine yog qhov tseem ceeb amino acid. Lub ntsiab zoo raws li hauv qab no:
(1) Ntxiv rau qhov lactations 'cov khoom noj ua kom cov mis ntxiv. Lub tshuab ua haujlwm yog L-Valine tuaj yeem cuam tshuam rau tiam alanine thiab tso tawm cov leeg, thiab qhov tshiab tau txais alanine nyob rau hauv lactations 'plasma txoj cai pab lub mis hloov kho rau qhov kev thov rau cov ntaub ntawv ntawm cov piam thaj thiab yog li cov mis tawm tuaj.
(2) Txhim kho cov tsiaj lub cev tsis muaj zog. L-Valine tuaj yeem txhawb cov pob txha tsiaj T cov hlwb kom hloov mus ua T cov hlwb. Lub sijhawm luv luv ntawm valine txo qis ntxiv C3 thiab qib hloov pauv, cuam tshuam kev loj hlob ntawm thymus thiab peripheral lymphoid nqaij thiab ua rau kev loj hlob inhibition rau cov kua qaub thiab cov ntshav dawb nruab nrab. Thaum tsis muaj valine, cov me nyaum qaib yuav ua qeeb qeeb thiab tsis muaj cov tshuaj tiv thaiv kev tiv thaiv kab mob rau Newcastle kab mob.
(3) Muaj kev cuam tshuam cov qib endocrine tsiaj. Cov kev tshawb fawb pom tias lactating sows thiab lactating nas 'kev noj zaub mov ntxiv nrog L-valine yuav ua rau muaj kev cia siab ntau ntawm prolactin thiab kev loj hlob hormone hauv lawv plasmas.
(4) L-valine kuj tseem ceeb rau lub hom phiaj kho cov ntaub so ntswg thiab kho kom rov zoo. Nws hu ua ceg ceg amino acid los yog BCAA, uas ua nrog rau ob lub BCAAs ntxiv uas hu ua L-Leucine thiab L-Isoleucine.
