Zvenyama uye zvemakemikari zvimiro zvethreonine

Kuonekwa: chena poda

Overview

L-threonine inokosha amino acid, uye threonine inonyanya kushandiswa mumishonga, makemikari reagents, zvokudya zvinosimbisa, zvokudya additives, etc. Kunyanya, kuwanda kwezvokudya zvinowedzera zvakakura nokukurumidza.Inowanzowedzerwa kune chikafu chediki nguruve nehuku, uye ndiyo yechipiri inodzikamisa amino acid mukudya kwenguruve uye yechitatu inodzikamisa amino acid mukudyisa huku.Kuwedzera L-threonine kukudya kwemusanganiswa kune zvinotevera hunhu: ① Inogona kugadzirisa amino acid chiyero chechikafu uye kukurudzira kukura kwezvipfuyo;② Inogona kuvandudza nyama yemhando;③ Inogona kuvandudza kukosha kwekudya kwezvikafu zvine yakaderera amino acid digestibility;④ Inogona kuderedza Mutengo wekudya mbishi zvinhu;saka, yakashandiswa zvakanyanya muindasitiri yezvekudya munyika dzeEU (kunyanya Germany, Belgium, Denmark, nezvimwewo) uye nyika dzeAmerica.

Yakanga yakaparadzaniswa uye yakaonekwa kubva kufibrin hydrolyzate neWCRose1935.Muna 1936, Meger akadzidza chimiro chayo chemuchadenga akachitumidza kuti threonine nekuda kwechimiro chayo chakafanana netatu.Kune ina isomers yethreonine, uye L-threonine ndiyo inongoitika yega uye ine physiological mhedzisiro pamuviri.

metabolic nzira

Iyo metabolic nzira yethreonine mumuviri yakasiyana nemamwe amino acids.Ndiyo chete iyo isingapindi dehydrogenase uye transamination, asi kuburikidza nethreonine dehydratase (TDH) uye threonine dehydration (TDG) uye aldehyde condensation.Amino acids anoshandurwa kuita zvimwe zvinhu zvinogadziriswa nema enzymes.Kune nzira nhatu huru: metabolized to glycine uye acetaldehyde nealdolase;metabolized to aminopropionic acid, glycine, uye acetyl COA neTDG;metabolized to propionic acid uye α-aminobutyric acid neTDH

Threonine chigadzirwa kushandiswa

Chinangwa chikuru

Threonine chinhu chakakosha chekudya kunovaka muviri, chinogona kusimbisa zviyo, zviyo, uye zvigadzirwa zvemukaka.Kufanana netryptophan, inogona kubvisa kuneta kwevanhu uye kukurudzira kukura nekukura.Mumushonga, nokuti chimiro che threonine chine mapoka e-hydroxyl, ine simba rekubata mvura paganda remunhu, rinosanganiswa ne-oligosaccharide maketani, rinoita basa rinokosha mukudzivirira masero emasero, uye rinogona kukurudzira phospholipid synthesis uye fatty acid oxidation mumuviri.Kugadzirira kune mushonga wekusimudzira kukura kwevanhu uye kuramba mafuta echiropa, uye inhengo yekomboni amino acid infusion.Panguva imwecheteyo, threonine zvakare ndiyo yakasvibiswa yekugadzirwa kwekirasi yemishonga inobudirira uye hypoallergenic antibiotics, monoamidocin.

Nzvimbo huru dzekudya: chikafu chakaviriswa (zviyo zvigadzirwa), mazai, chrysanthemum, mukaka, nzungu, mupunga, makarotsi, miriwo yemashizha, papaya, alfalfa, nezvimwe.

Threonine inoshandiswa mumishonga, makemikari reagents, zvokudya zvinosimbisa, zvokudya zvinowedzera, nezvimwewo, kunyanya kuwanda kwezvokudya zvinowedzera zvakakura nokukurumidza.Inowanzowedzerwa kune chikafu chediki nguruve nehuku, uye ndiyo yechipiri inodzikamisa amino acid mukudya kwenguruve uye yechitatu inodzikamisa amino acid mukudyisa huku.[4]

Nekuvandudzwa kwemararamiro evanhu uye kuvandudzwa kweaquaculture, threonine, seamino acid yekudyisa, inoshandiswa zvakanyanya kuwedzera chikafu chenguruve, kufudza chikafu chenguruve, chikafu chebroiler, chikafu cheshrimp uye eel feed.Ine zvinotevera maitiro:

——Gadzirisa chiyero cheamino acid muchikafu kusimudzira kukura;

- inogona kuvandudza kunaka kwenyama;

- inogona kuvandudza kukosha kwekudya kwezvikafu zvekudya zvine yakaderera amino acid digestibility;

--Inogona kuburitsa pasi-protein feed, iyo inobatsira kuchengetedza mapuroteni zviwanikwa;

--Inogona kuderedza mutengo wekudya mbishi zvinhu;

--Inogona kuderedza iyo nitrogen yemukati muzvipfuyo nehuku manyowa uye weti, uye iyo ammonia yekumisikidza uye chiyero chekuburitsa muzvipfuyo nehuku dzimba.

Parizvino, vesainzi vekuGermany vakawana threonine muropa remunhu, uye ongororo dzakaonekwa kuti inogona kudzivirira HIV kuti isabatane nekupinda mumasero emasomatic, nekuvhiringa puroteni yepamusoro yeHIV, zvichiita kuti itadze kushanda.Kuwanikwa kweamino acid iyi kunopa nzira yekugadzirwa kwemishonga inorwisa AIDS.

Kudikanwa kwekushandisa kudyisa

Parizvino, kushaikwa kwechikafu chekudya, kunyanya kushaikwa kwechikafu cheprotein sehupfu hwesoya bean nehove, zvinokanganisa budiriro yekupfuya zvipfuyo.Threonine inowanzova yechipiri kana yechitatu inodzikamisa amino acid mukudya kwenguruve, uye yechitatu kana yechina inodzikamisa amino acid mukudya kwehuku.Nekushandiswa kwakakura kwe lysine uye methionine zvigadzirwa zvekugadzira mukomboni chikafu, zvishoma nezvishoma Yakave chinhu chikuru chinomisa chinokanganisa kushanda kwezvipfuyo nehuku, kunyanya mushure mekuwedzera lysine mune yakaderera-protein kudya, threonine yave yekutanga kudzikamisa amino acid. zvekurima nguruve.

Kana threonine isingashandiswi mukudya, mutemo we threonine muzvokudya unogona kuvimba chete neprotein yakasvibirira zvinhu, uye mapuroteni akasvibirira ane kwete threonine chete, asiwo mamwe anokosha uye asingakoshi amino acids.Mhedzisiro yekushandisa threonine kugadzirisa chiyero cheamino acid ndeyekuti iyo amino acid chiyero chekudya hachigone kuvandudzwa zvakanyanya sezvinobvira, kutambisa kwehuwandu hwakawanda hweakakosha amino acids hakugone kuderedzwa zvakare, uye formula mutengo wekudya. haigoni kuwedzera kuderedzwa.Chikumbaridzo chinofanirwa kuyambukwa kuvandudza amino acid chiyero idambudziko remabhodhoro iro vese vanogadzira havagone kudzivirira.

Kushandiswa kwe threonine kunogona kuderedza marara eakakosha uye asina kukosha amino acids, kana kuderedza crude protein level yechikafu.Chikonzero chacho chakafanana nekushandisa lysine hydrochloride.Huwandu hweprotein hwekudya hunogona kuwanikwa nekushandisa crystalline amino acids.Kuderedzwa kunonzwisisika, kugadzirwa kwemhuka hakuzokuvadzwa, asi kunogona kuvandudzwa.
