Lub cev thiab tshuaj muaj zog ntawm threonine

Qhov tsos: dawb hmoov

Txheej txheem cej luam

L-threonine yog ib qho tseem ceeb amino acid, thiab threonine feem ntau yog siv rau hauv cov tshuaj, tshuaj reagents, zaub mov fortifiers, pub additives, thiab lwm yam. tshwj xeeb tshaj yog, tus nqi pub additives tau loj hlob sai heev.Nws yog feem ntau ntxiv rau pub ntawm cov tub ntxhais hluas piglets thiab nqaij qaib, thiab yog qhov thib ob limiting amino acid nyob rau hauv npua pub thiab thib peb limiting amino acid nyob rau hauv nqaij qaib pub.Ntxiv L-threonine rau compound pub muaj cov yam ntxwv hauv qab no: ① Nws tuaj yeem kho cov amino acid tshuav nyiaj li cas ntawm cov khoom noj thiab txhawb kev loj hlob ntawm cov tsiaj nyeg;② Nws tuaj yeem txhim kho nqaij zoo;③ Nws tuaj yeem txhim kho cov khoom noj muaj txiaj ntsig ntawm cov khoom noj nrog cov amino acid digestibility tsawg;④ Nws tuaj yeem txo tus nqi ntawm cov khoom noj khoom haus;Yog li ntawd, nws tau siv dav hauv kev lag luam pub khoom noj hauv EU lub teb chaws (feem ntau lub teb chaws Yelemees, Belgium, Denmark, thiab lwm yam) thiab Asmeskas lub teb chaws.

Tshawb nrhiav

Nws raug cais tawm thiab txheeb xyuas los ntawm fibrin hydrolyzate los ntawm WCRose1935.Xyoo 1936, Meger tau kawm txog nws cov qauv spatial thiab hu ua threonine vim nws cov qauv zoo sib xws rau threose.Muaj plaub isomers ntawm threonine, thiab L-threonine yog ib qho uas tshwm sim ib txwm muaj thiab muaj kev cuam tshuam rau lub cev.

txoj kev metabolic

Txoj kev metabolic ntawm threonine hauv lub cev yog txawv ntawm lwm cov amino acids.Nws yog tib qho uas tsis muaj dehydrogenase thiab transamination, tab sis los ntawm threonine dehydratase (TDH) thiab threonine dehydration (TDG) thiab aldehyde condensation.Amino acids uas hloov mus rau lwm yam tshuaj catalyzed los ntawm enzymes.Muaj peb txoj hauv kev tseem ceeb: metabolized rau glycine thiab acetaldehyde los ntawm aldolase;metabolized rau aminopropionic acid, glycine, thiab acetyl COA los ntawm TDG;metabolized rau propionic acid thiab α-aminobutyric acid los ntawm TDH

Kev siv cov khoom siv Threonine

Lub hom phiaj tseem ceeb

Threonine yog ib qho tseem ceeb ntawm kev noj zaub mov zoo, uas tuaj yeem tiv thaiv cov nplej, ncuav pastries, thiab khoom noj siv mis.Zoo li tryptophan, nws tuaj yeem txo cov neeg qaug zog thiab txhawb kev loj hlob thiab kev loj hlob.Hauv cov tshuaj, vim tias cov qauv ntawm threonine muaj cov pab pawg hydroxyl, nws muaj cov nyhuv dej tuav ntawm tib neeg cov tawv nqaij, ua ke nrog oligosaccharide chains, ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cell membranes, thiab tuaj yeem txhawb phospholipid synthesis thiab fatty acid oxidation hauv lub cev.Kev npaj muaj cov nyhuv tshuaj ntawm kev txhawb nqa tib neeg txoj kev loj hlob thiab tiv thaiv lub siab rog, thiab yog ib feem ntawm compound amino acid infusion.Nyob rau tib lub sijhawm, threonine tseem yog cov khoom siv raw rau kev tsim cov chav kawm ntawm cov tshuaj tua kab mob hypoallergenic, monoamidocin.

Cov khoom noj tseem ceeb: cov khoom noj fermented (cov khoom lag luam), qe, chrysanthemum, mis nyuj, txiv laum huab xeeb, mov, carrots, nplooj zaub, papaya, alfalfa, thiab lwm yam.

Threonine yog siv rau hauv cov tshuaj, tshuaj reagents, zaub mov fortifiers, pub additives, thiab lwm yam. tshwj xeeb tshaj yog, tus nqi pub additives tau loj hlob sai heev.Nws yog feem ntau ntxiv rau pub ntawm cov tub ntxhais hluas piglets thiab nqaij qaib, thiab yog qhov thib ob limiting amino acid nyob rau hauv npua pub thiab thib peb limiting amino acid nyob rau hauv nqaij qaib pub.[4]

Nrog rau kev txhim kho ntawm tib neeg kev ua neej nyob thiab kev loj hlob ntawm aquaculture, threonine, raws li ib tug amino acid rau pub, yog dav siv los ntxiv piglet pub, yug me nyuam npua noj, broiler pub, cw noj thiab eel pub.Nws muaj cov yam ntxwv hauv qab no:

—— Kho cov amino acid tshuav nyiaj li cas hauv kev pub kom txhawb kev loj hlob;

- tuaj yeem txhim kho nqaij zoo;

- tuaj yeem txhim kho cov khoom noj muaj txiaj ntsig ntawm cov khoom xyaw pub nrog tsawg amino acid digestibility;

—— Nws tuaj yeem tsim cov khoom noj muaj protein tsawg, uas pab txuag cov khoom siv protein;

—— Nws tuaj yeem txo tus nqi ntawm cov khoom noj khoom haus;

—— Nws tuaj yeem txo cov ntsiab lus nitrogen hauv cov tsiaj nyeg thiab nqaij qaib thiab cov zis, thiab cov ammonia concentration thiab tso tawm tus nqi hauv cov tsiaj txhu thiab cov tsev qaib.

Tam sim no, cov kws tshawb fawb German tau tshawb pom muaj threonine hauv tib neeg cov ntshav, thiab cov kev sim tau pom tias nws tuaj yeem tiv thaiv HIV los ntawm kev sib txuas thiab cuam tshuam cov hlwb somatic, los ntawm kev cuam tshuam nrog cov protein ntau ntawm HIV, ua rau nws tsis tuaj yeem ua haujlwm.Kev tshawb pom ntawm cov amino acid no muab txoj hauv kev rau kev txhim kho cov tshuaj tiv thaiv AIDS.

Qhov tsim nyog rau daim ntawv thov pub

Tam sim no, cov txheeb ze tsis muaj peev txheej pub, tshwj xeeb tshaj yog tsis muaj protein ntau xws li zaub mov taum thiab ntses noj, txwv tsis pub txoj kev loj hlob ntawm tsiaj txhu.Threonine feem ntau yog qhov thib ob lossis thib peb txwv cov amino acid hauv npua pub, thiab thib peb lossis plaub txwv cov amino acid hauv nqaij qaib noj.Nrog rau kev siv dav dav ntawm lysine thiab methionine hluavtaws cov khoom hauv cov khoom noj sib xyaw, nws maj mam dhau los ua qhov tseem ceeb txwv tsis pub muaj kev cuam tshuam rau kev ua haujlwm ntawm cov tsiaj nyeg thiab nqaij qaib, tshwj xeeb tshaj yog tom qab ntxiv lysine hauv cov khoom noj muaj protein tsawg, threonine tau dhau los ua thawj qhov txwv amino acid. rau npua loj hlob.

Yog tias threonine tsis siv rau hauv kev pub noj, kev tswj hwm ntawm threonine hauv kev pub noj tsuas yog tso siab rau cov khoom siv protein, thiab cov khoom siv protein ntau tsis tsuas yog threonine xwb, tab sis kuj muaj lwm yam tseem ceeb thiab tsis tseem ceeb amino acids.Qhov tshwm sim ntawm kev siv threonine los kho cov amino acid tshuav nyiaj li cas yog tias cov amino acid tshuav nyiaj li cas ntawm cov khoom noj tsis tuaj yeem txhim kho ntau npaum li qhov ua tau, cov khoom pov tseg ntawm ntau qhov tseem ceeb amino acids tsis tuaj yeem txo qis ntxiv, thiab tus nqi ntawm cov khoom noj. tsis tuaj yeem txo qis ntxiv.Qhov chaw pib uas yuav tsum tau hla los txhim kho cov amino acid tshuav nyiaj li cas yog qhov teeb meem uas txhua tus tsim tawm tsis tuaj yeem zam.

Kev siv threonine tuaj yeem txo qhov pov tseg ntawm qhov tseem ceeb thiab tsis tseem ceeb amino acids, lossis txo qis cov protein ntau ntawm cov khoom noj.Qhov laj thawj yog tib yam li siv lysine hydrochloride.Cov qib protein crude ntawm pub tuaj yeem tau los ntawm kev siv crystalline amino acids.Kev txo qis, kev tsim khoom ntawm cov tsiaj yuav tsis raug puas tsuaj, tab sis kuj tuaj yeem txhim kho.
