L-Tryptophan | 73-22-3 ib
Khoom Description
Tryptophan (IUPAC-IUBMB abbreviation: Trp lossis W; IUPACabbreviation: L-Trp lossis D-Trp; muag rau kev kho mob siv raws li Tryptan) yog ib qho ntawm 22 tus qauv amino acids thiab ib qho tseem ceeb amino acid nyob rau hauv tib neeg kev noj haus, raws li pom los ntawm nws txoj kev loj hlob. cuam tshuam rau nas. Nws yog encoded nyob rau hauv tus qauv genetic code raws li lub codon UGG. Tsuas yog L-stereoisomer ntawm tryptophan tsuas yog siv cov txheej txheem los yog cov enzyme proteins, tab sis cov R-stereoisomer muaj qee zaus pom.unib txwm ua peptides (piv txwv li, marine venom peptide contryphan).Qhov txawv ntawm cov yam ntxwv ntawm tryptophan yog tias nws muaj cov pab pawg ua haujlwm indole.
Muaj pov thawj tias cov ntshav tryptophan tsis zoo li yuav hloov pauv los ntawm kev hloov cov khoom noj, tab sis qee lub sijhawm, tryptophan tau muaj nyob hauv cov khw muag khoom noj qab haus huv raws li kev noj haus ntxiv.
Kev tshawb fawb soj ntsuam tau pom cov txiaj ntsig sib xyaw nrog kev hwm rau tryptophan qhov ua tau zoo asa pw tsaug zog pab, tshwj xeeb tshaj yog rau cov neeg mob ib txwm muaj. Tryptophan tau qhia qee qhov ua tau zoo rau kev kho mob ntau yam ntawm lwm yam mob feem ntau cuam tshuam nrog qis serotonin hauv lub hlwb. Hauv particular, tryptophan tau qhia qee qhov kev cog lus raws li ib qho tshuaj tiv thaiv kev nyuaj siab ib leeg thiab ua "augmenter" ntawm cov tshuaj antidepressant. Txawm li cas los xij, qhov kev ntseeg siab ntawm cov kev sim tshuaj no tau raug nug vim tsis muaj kev tswj hwm thiab rov ua dua. Tsis tas li ntawd, tryptophan nws tus kheej yuav tsis muaj txiaj ntsig hauv kev kho mob kev nyuaj siab lossis lwm yam kev xav ntawm serotonin, tab sis tej zaum yuav muaj txiaj ntsig zoo rau kev nkag siab txog cov txheej txheem tshuaj uas yuav muab cov lus qhia tshiab rau kev tshawb fawb tshuaj.
