I-L-(-)-Threonine (H-Thr-OH; i-Thr efinyeziweyo okanye i-T) (i-CAS: i-72-19-5) isetyenziselwa uphando lwe-biochemical, njengeyeza lezondlo ze-amino acid kwiyeza, ezisetyenziswa kakhulu kunyango lwe-anemia.Amino acid amachiza.ISongezo seSondlo.
I-L-Threonine ingasetyenziselwa kwishishini lokutya kwizongezelelo zesondlo, zongezwa ekudleni, i-L-Threonine inokuphucula ixabiso lesondlo seprotheni, ukwenzela ukuba izondlo zokutya ezaneleyo zinengqondo.I-L-Threonine kunye neglucose yayishushu, inevumba elimnandi kwaye kulula ukuvelisa incasa yetshokholethi yecoke kwisiphuculi sencasa kwindima yokwenziwa kokutya.
I-L-Threonine kwishishini lokutya, i-L-Threonine amino acids ingasetyenziselwa njengezongezo zokutya kwiprotheyini yokutya iye yavula iindlela ezintsha, i-L-Threonine ayiphuculi kuphela ixabiso lesondlo sokutya, ukunciphisa iindleko zokutya.Kodwa kwakhona ukufumana ukukhuthaza ukukhula kwezilwanyana kunye nophuhliso, ukomeleza ukumelana nezifo kunye nezinye iziphumo ezininzi eziluncedo.
I-L-Threonine iyimfuneko ukuze izilwanyana zigcine ukukhula, izilwanyana azikwazi ukuhlanganiswa.Kufuneka isuke kubonelelo lokutya.Ukungabikho kwe-L-Threonine kunokukhokelela ekunciphiseni ukutya kwezilwanyana.Ukucutheka, ukusebenza kakuhle kwesondlo kunciphisa iimpawu zokunciphisa umsebenzi wokuzivikela omzimba.I-L-Threonine yi-methionine yesibini, i-lysine, i-tryptophan, i-amino acids eyimfuneko emva kwe-additive feed yemfuyo yesine, i-L-Threonine yokukhula kwemfuyo kunye nophuhliso, ukuqinisa ukutyeba, ukuncelisa, ukuveliswa kweqanda kwakuququzelela kakhulu indima.
I-Threonine luhlobo olubalulekileyo lwe-analeptic eyomeleza i-cereal, i-pastry kunye neemveliso zobisi. Njenge-tryptophan, ivuselela imizimba yabantu kwaye ikhuthaze ukukhula kweentsana. kunye ne-oligose, ikhusela iimbumba zeseli yomntu, kwaye ikhawulezisa ukuhlanganiswa kwe-phosphatide kunye ne-oxidation ye-acid enamafutha. ukuveliswa kwe-monobactam, enye ye-antibiotics ephezulu kunye ne-low-allergies.
Njenge-amino acid ye forge, ithreonine yongezwa ngokubanzi kwifula yehagu esandul' ukuzalwa, ihagu egqumatheleyo, inkukhu, i-shrimp, i-eel kunye nokunye.
-Gcina ibhalansi ye-amino acids kwi-forage kwaye ikhuthaze ukukhula kwezilwanyana;
-Phucula umgangatho wenyama;
-Ukwandisa ixabiso lezondlo zefula ekrwada ezinokutya okuphantsi kwe-amino acid;
-Faka kwimveliso eneprotheyini encinci;
-Ukunciphisa iindleko zemathiriyeli ekrwada yefula;
-Ukunciphisa umthamo we-nitrogen kwilindle kunye nomchamo wezilwanyana ukuze ukukhutshwa kwe-ammonia kucothiswe kwaye ukuxinwa kwe-ammonia kugcinwe kuphantsi kwishedi yezilwanyana.
