L-(-)-Threonine (H-Thr-OH; Fa'apu'upu'u Thr po'o T) (CAS: 72-19-5) e fa'aaogaina mo su'esu'ega biochemical, e pei o le amino acid nutrition medicine i vaila'au, e masani ona fa'aaogaina i le togafitiga o le anemia.vaila'au amino acid.Mea'ai Fa'aopoopo.
L-Threonine e mafai ona faʻaaogaina i le alamanuia o meaʻai i meaʻai faaopoopo, faʻaopoopo i meaʻai, L-Threonine e mafai ona faʻaleleia le taua o meaʻai o le porotini, ina ia lava meaʻai taumafa e sili atu ona talafeagai.O le L-Threonine ma le kulukose e vevela, manogi ma faigofie ona gaosia le tofo sukalati coke i se faʻaleleia atili o meaʻai i le gaosiga o meaʻai.
L-Threonine i le alamanuia fafaga, L-Threonine amino acids e mafai ona faʻaaogaina e fai ma fafaga faʻapipiʻi mo le fafagaina o le polotini ua tatalaina auala fou, L-Threonine e le gata ina faʻaleleia le tau o meaʻai, faʻaitiitia tau fafaga.Ae ia faʻamalosia foi le tuputupu aʻe ma le atinaʻeina o manu, faʻaleleia le faʻamaʻi faʻamaʻi ma le tele o isi mea aoga.
L-Threonine e manaʻomia mo manu e faʻatumauina le tuputupu aʻe, e le mafai ona faʻapipiʻiina manu.E tatau ona sau mai mea'ai.O le leai o le L-Threonine e mafai ona taʻitaʻia ai le faʻaititia o manu.Fa'ate'a, lelei fafaga fa'aitiitiga fa'ailoga fa'agata.L-Threonine o le methionine lona lua, lysine, tryptophan, amino acids taua ina ua uma le fafaga fafaga faaopoopo, L-Threonine o le tuputupu ae o lafumanu ma le atinae, faamalosia le gaʻo, lactation, fuamoa gaosiga sa matua faafaigofieina matafaioi.
Threonine o se ituaiga taua o analeptic lea fortifies cereal, pastry ma oloa susu. E pei o le tryptophan, e toe faʻafouina le tino o le tagata ma faʻaleleia le tuputupu aʻe o pepe. Pe a faʻaaogaina i le falemaʻi, e mafai e le threonine ona susu paʻu o tagata ona o le hydroxy i lona fausaga. Combined. faʻatasi ai ma le oligose, e puipuia ai sela o le tagata, ma faʻavaveina le faʻapipiʻiina o le phosphatide ma le faʻamaʻiina o le gaʻo gaʻo. Faatasi ai ma se togafitiga faafomaʻi o le puipuia o le ate gaʻo, o le sauniuniga o le threonine e galue o se vaega o tui amino acid, I le taimi nei, e mafai ona faʻaaogaina le threonine mo le gaosiga o monobactams, o se tasi o vailaʻau faʻamaʻi maualuga ma maualalo-allergy.
I le avea ai o le amino acid mo le faʻamalosi, o le threonine e faʻaopoopoina lautele i le faga mo puaa faatoa fanau mai, ufiufi puaa, moa, ula, tuna ma faapena. E mafai ona:
- Taofi le paleni o amino acids i le faga ma faʻaosofia le tuputupu aʻe o manu;
- Fa'aleleia le lelei o aano o manufasi;
- Fa'ateleina le aoga o mea'ai fa'ato'aga o lo'o maualalo le fa'amamafaina o le amino acid;
-Talosaga i le gaosiga maualalo-protein forage;
- Fa'aiti i lalo le tau o mea mata mo faga;
- Fa'aitiitia le fa'aogaina o le nitrogen i le otaota ma le mimi o manu ina ia fa'agesegese le tu'uina atu o le ammonia ma fa'amaulalo ai le fa'amalieina o le ammonia i totonu o le fale manu.
