L-(-) Threonine (H-Thr-OH; Soo gaabiyey Thr ama T) (CAS: 72-19-5) waxaa loo isticmaalaa cilmi-baarista biochemical, sida dawada nafaqada amino acid ee daawada, inta badan loo isticmaalo daaweynta dhiig-yaraan.Daawooyinka Amino acid.Kaabista Nafaqada.
L-Threonine waxaa loo isticmaali karaa warshadaha cuntada ee nafaqada nafaqada, lagu daro cuntada, L-Threonine waxay hagaajin kartaa qiimaha nafaqada ee borotiinka, si nafaqooyin cunto oo ku filan ay macquul tahay.L-Threonine iyo gulukoosku waxay ahaayeen kuwo kulul, udgoon oo fudud in la soo saaro dhadhan shukulaatada kookaha ee dhadhamin roonaanta doorka habaynta cuntada.
L-Threonine ee warshadaha quudinta, L-Threonine acids amino waxaa loo isticmaali karaa sida lagu daro quudinta sahayda quudinta borotiinka ayaa furay wadooyin cusub, L-Threonine kaliya ma wanaajiso qiimaha nafaqada ee quudinta, yaraynta kharashka quudinta.Laakin sidoo kale hel si kor loogu qaado korriinka iyo korriinka xoolaha, kor u qaad iska caabinta cudurka iyo saameyno kale oo badan oo faa'iido leh.
L-Threonine waxay lagama maarmaan u tahay xayawaanka si ay u ilaaliyaan korriinka, xayawaanka lama samayn karo.Waa inuu ka yimid sahayda cuntada.L-Threonine la'aanta waxay keeni kartaa in la yareeyo qaadashada xoolaha.Hoos u dhaca, waxtarka quudinta ayaa hoos u dhigtay calaamadaha xakamaynta shaqada difaaca.L-Threonine waa methionine-ka labaad, lysine, tryptophan, amino acids lagama maarmaanka u ah ka dib quudinta afraad ee xoolaha, L-Threonine ee koritaanka xoolaha iyo horumarinta, xoojinta naaxinta, nuujinta, wax soo saarka ukunta ayaa si weyn u fududeeyay doorka.
Threonine waa nooc muhiim ah oo analeptic ah oo xoojisa badarka, baastada iyo caanaha. Sida tryptophan, waxay cusboonaysiisaa jidhka bini'aadamka waxayna kor u qaadaa koritaanka dhallaanka leh oligose, waxay ilaalisaa xuubabka unugyada bini'aadamka, waxayna dedejisaa isku-dhafka fosfatide iyo oksaydhka ee acid dufanka leh. soo saarida monobactams, mid ka mid ah antibiyootiga saamaynta sare leh iyo kuwa hooseeya.
Sida amino acid forge, threonine waxaa si weyn loogu daray in calafka doofaarka dhawaan dhashay, oo daboolaya doofaarka, digaaga, shrimp, eel iyo wixii la mid ah.
-Isku-dheellitirka asiidhyada amino-yada ee calafka calafka iyo kicin koritaanka xayawaanka;
-Hagaajinta tayada hilibka;
- Kordhi qiimaha nafaqada ee alaabta ceeriin calafka oo leh dheefshiidka amino acid hooseeya;
-Codso wax soo saarka calafka borotiinku ku yar yahay;
-La dhimo qiimaha alaabta ceeriin ee calafka;
-Waxay yaraysaa maadada nitrogen ee ku jirta saxarada iyo kaadida xoolaha si soo daynta ammonia ay u yaraato, fiirsashada ammonia-na ay ku yaraato xadhkaha xoolaha.
