I-L-(-)-Threonine (H-Thr-OH; I-Thr noma i-T Efushanisiwe) (i-CAS: 72-19-5) isetshenziselwa ucwaningo lwe-biochemical, njengomuthi wokudla okunomsoco we-amino acid emithini, ikakhulukazi esetshenziselwa ukwelashwa kwe-anemia.Izidakamizwa ze-amino acid.Isengezo Sokudla Okunomsoco.
I-L-Threonine ingasetshenziswa embonini yokudla ezithasiselweni zokudla okunomsoco, yengezwe ekudleni, i-L-Threonine ingathuthukisa inani lokudla okunomsoco wamaprotheni, ukuze imisoco yokudla eyanele inengqondo.I-L-Threonine kanye ne-glucose kwakushisa, kunuka kamnandi futhi kulula ukukhiqiza ukunambitheka kukashokoledi we-coke kusithuthukisi ukunambitheka endimeni yokucubungula ukudla.
I-L-Threonine embonini yokudla, i-L-Threonine amino acids ingasetshenziswa njengezithasiselo zokuphakelayo kokuphakelayo kwamaprotheni ivule izindlela ezintsha, i-L-Threonine ayigcini nje ngokuthuthukisa inani lokudla okunomsoco, ukunciphisa izindleko zokudla.Kodwa futhi uthole ukukhuthaza ukukhula nokuthuthuka kwezilwane, ukuthuthukisa ukumelana nezifo kanye neminye imiphumela eminingi enenzuzo.
I-L-Threonine iyadingeka ukuze izilwane zilondoloze ukukhula, izilwane azikwazi ukuhlanganiswa.Kufanele isuke ekutholakaleni kokudla.Ukuntuleka kwe-L-Threonine kungaholela ekwehliseni ukudla kwezilwane.Imangele, ukusebenza kahle kokuphakelayo kwehlisa izimpawu zokucindezelwa komsebenzi wokuzivikela komzimba.I-L-Threonine iyi-methionine yesibili, i-lysine, i-tryptophan, ama-amino acid abalulekile ngemva kwesengezo sesine sokudla kwemfuyo, i-L-Threonine yokukhula nokuthuthukiswa kwemfuyo, ukuqinisa ukukhuluphala, ukuncelisa, ukukhiqizwa kwamaqanda kwakubaluleke kakhulu indima.
I-Threonine iwuhlobo olubalulekile lwe-analeptic oluqinisa ama-cereal, amakhekhe kanye nemikhiqizo yobisi. Njenge-tryptophan, ivuselela imizimba yabantu futhi ikhuthaze ukukhula kwezinsana. Uma isetshenziswa emkhakheni wezokwelapha, i-threonine ingamanzisa izikhumba zabantu ngenxa ye-hydroxy esakhiweni sayo. nge-oligose, ivikela ulwelwesi lwamangqamuzana omuntu, futhi isheshisa ukwakheka kwe-phosphatide kanye ne-oxidation yamafutha acid. Ngomphumela wokwelapha wokuvimbela isibindi esinamafutha, ukulungiswa kwe-threonine kusebenza njengengxenye yomjovo we-amino acid ehlanganisiwe, Okwamanje, i-threonine ingasetshenziselwa ukukhiqizwa kwe-monobactam, enye yemithi elwa namagciwane enamandla kakhulu futhi ephansi.
Njenge-amino acid ye-forge, i-threonine yengezwa kabanzi ekudleni kwengulube esanda kuzalwa, emboza ingulube, izinkukhu, izimfanzi, umbokwane nokunye.
-Gcina ibhalansi yama-amino acids ekudleni futhi ukhuthaze ukukhula kwezilwane;
-Thuthukisa ikhwalithi yenyama;
-Khulisa inani lokudla okunomsoco we-forage izinto ezingavuthiwe ezinokugayeka kokudla okuphansi kwe-amino acid;
-Faka ekukhiqizeni ifolishi ephansi yamaprotheni;
-Yehlisa izindleko zempahla eluhlaza ukuze uthole ifolishi;
-Yehlisa okuqukethwe kwe-nitrogen endle nasemchamweni wezilwane ukuze ukukhishwa kwe-ammonia kunciphe futhi ukugcwala kwe-ammonia kugcinwe kuphansi eshedini lezilwane.
