Iimpawu zomzimba kunye neekhemikhali zethreonine
Ukubonakala: umgubo omhlophe
Isishwankathelo
I-L-threonine i-amino acid eyimfuneko, kwaye i-threonine isetyenziselwa kakhulu amayeza, ii-reagents zekhemikhali, iziqinisekiso zokutya, izongezo zokutya, njl. Ngokukodwa, inani lezongezo zokutya liye lakhula ngokukhawuleza.Ihlala idityaniswa kwisondlo samantshontsho eehagu ezincinci kunye neenkukhu, kwaye iyindawo yesibini ethintela i-amino acid ekutyeni kweehagu kunye neyesithathu inciphisa i-amino acid ekutyeni kweenkukhu.Ukongeza i-L-threonine kwisondlo esixubeneyo kunezi mpawu zilandelayo: ① Inokulungelelanisa ukulingana kwe-amino acid yesondlo kwaye ikhuthaze ukukhula kwemfuyo;② Inokuphucula umgangatho wenyama;③ Inokuphucula ixabiso lesondlo sokutya kunye ne-amino acid ephantsi yokwetyisa;④ Inokunciphisa ixabiso lempahla ekrwada;ngoko ke, isetyenziswe ngokubanzi kwishishini lokutya kumazwe e-EU (ikakhulukazi iJamani, iBelgium, iDenmark, njl.) kunye namazwe aseMelika.
Fumana
Yahlukaniswa kwaye ichongiwe kwi-fibrin hydrolyzate ngu-WCRose1935.Ngo-1936, uMeger wafunda ubume bayo besithuba waza wayibiza ngokuba yithreonine ngenxa yolwakhiwo olufana nolwe-threose.Kukho ii-isomers ezine zethreonine, kwaye i-L-threonine yile yenzeka ngokwemvelo kwaye ineziphumo zomzimba emzimbeni.
indlela ye-metabolic
Indlela ye-metabolic ye-threonine emzimbeni yahlukile kwezinye ii-amino acids.Nguye kuphela ongenayo i-dehydrogenase kunye ne-transamination, kodwa nge-threonine dehydratase (TDH) kunye ne-threonine dehydration (TDG) kunye ne-aldehyde condensation.Ii-amino acids eziguqulwa zibe zezinye izinto ezenziwa yi-enzymes.Kukho iindlela ezintathu eziphambili: i-metabolized kwi-glycine kunye ne-acetaldehyde nge-aldolase;i-metabolized kwi-aminopropionic acid, i-glycine, kunye ne-acetyl COA nge-TDG;i-metabolized kwi-propionic acid kunye ne-α-aminobutyric acid nge-TDH
Ukusetyenziswa kwemveliso ye-Threonine
Injongo ephambili
I-Threonine yeyona nto ibalulekileyo yokuqinisa isondlo, enokomeleza iisiriyeli, iipastries, kunye neemveliso zobisi.Njenge-tryptophan, inokuphelisa ukudinwa komntu kwaye ikhuthaze ukukhula nophuhliso.Kwiyeza, ngenxa yokuba isakhiwo se-threonine siqukethe amaqela e-hydroxyl, inomphumo wokubamba amanzi kwesikhumba somntu, idibene namaketanga e-oligosaccharide, idlala indima ebalulekileyo ekukhuseleni iimbumba zeeseli, kwaye inokukhuthaza i-phospholipid synthesis kunye ne-fatty acid oxidation emzimbeni.Ukulungiswa kunempembelelo yonyango yokukhuthaza ukuphuhliswa komntu kunye nokuchasana nesibindi esinamafutha, kwaye inxalenye ye-compound amino acid infusion.Kwangaxeshanye, i-threonine ikwayimathiriyeli ekrwada yokwenziwa kweklasi ye-antibiotics esebenzayo kakhulu kunye ne-hypoallergenic, i-monoamidocin.
Imithombo yokutya ephambili: ukutya okuvundisiweyo (imveliso yeecereal), amaqanda, i-chrysanthemum, ubisi, amantongomane, irayisi, iminqathe, imifuno enamagqabi, ipapaya, ialfalfa, njl.
I-Threonine isetyenziselwa amayeza, i-reagents yeekhemikhali, iziqinisekiso zokutya, izongezo zokutya, njl. Ngokukodwa, inani lezongezo zokutya liye lakhula ngokukhawuleza.Ihlala idityaniswa kwisondlo samantshontsho eehagu ezincinci kunye neenkukhu, kwaye iyindawo yesibini ethintela i-amino acid ekutyeni kweehagu kunye neyesithathu inciphisa i-amino acid ekutyeni kweenkukhu.[4]
Ngokuphuculwa kwemigangatho yokuphila kwabantu kunye nophuhliso lwe-aquaculture, i-threonine, njenge-amino acid yokutya, isetyenziselwa ngokubanzi ukongeza ukutya kweehagu, ukufuya ukutya kwehagu, ukutya kwe-broiler, ukutya kwe-shrimp kunye ne-eel feed.Inezi mpawu zilandelayo:
——Lungisa ibhalansi yeamino acid kwifidi ukukhuthaza ukukhula;
- inokuphucula umgangatho wenyama;
- inokuphucula ixabiso lesondlo sezithako zokutya kunye ne-amino acid digestibility ephantsi;
——Inokuvelisa ukutya okuneprotheyini ephantsi, enceda ukugcina izibonelelo zeprotheyini;
——Inokunciphisa ixabiso lempahla ekrwada;
--Inokunciphisa umxholo we-nitrogen kwimfuyo kunye nomgquba weenkukhu kunye nomchamo, kunye nogxininiso lwe-ammonia kunye nesantya sokukhululwa kwimfuyo kunye nezindlu zeenkukhu.
Okwangoku, oosonzululwazi baseJamani bafumanise i-threonine egazini lomntu, kwaye imifuniselo ifumanise ukuba inokuthintela i-HIV ekubeni incamathele kwaye ingenelele kwiiseli ze-somatic, ngokuphazamisana neprotein engaphezulu ye-HIV, iyenze ingakwazi ukusebenza.Ukufunyanwa kwale amino acid kunika umendo wophuhliso lwamachiza okulwa noGawulayo.
Imfuneko yesicelo ukondla
Okwangoku, ukunqongophala kwemithombo yokutya, ngakumbi ukunqongophala kwesondlo seprotheyini esifana nomgubo weembotyi zesoya kunye nomgubo wentlanzi, kuthintela kakhulu uphuhliso lokufuywa kwezilwanyana.I-Threonine ikholisa ukuba yi-amino acid yesibini okanye eyesithathu ekunciphiseni ukutya kweehagu, kwaye eyesithathu okanye yesine inciphisa i-amino acid ekutyeni kweenkukhu.Ngokusetyenziswa okubanzi kweemveliso ze-lysine kunye ne-methionine zokwenziwa kwi-compound feed, ngokuthe ngcembe iye yaba yeyona nto iphambili yokuthintela echaphazela ukusebenza kwemfuyo kunye neenkukhu, ngakumbi emva kokongeza i-lysine kwizidlo ezineprotheni ephantsi, i-threonine iye yaba yeyona nto iphambili yokunciphisa i-amino acid. kwiihagu ezikhulayo.
Ukuba i-threonine ayisetyenziswanga kwisondlo, ukulawulwa kwe-threonine kwisondlo kunokuthembela kuphela kwiprotheyini ekrwada, kunye neprotheyini ekrwada iqulethe i-threonine kuphela, kodwa kunye nezinye ii-amino acids ezibalulekileyo nezingabalulekanga.Isiphumo sokusebenzisa i-threonine ukulungelelanisa ibhalansi ye-amino acid kukuba ibhalansi ye-amino acid yesondlo ayinakuphuculwa kangangoko kunokwenzeka, inkunkuma yesixa esikhulu se-amino acids ebalulekileyo ayinakuncitshiswa ngakumbi, kunye neendleko zefomula yokutya. ayinakuncitshiswa ngakumbi.Umda omele ugqitywe ukuphucula ibhalansi ye-amino acid yingxaki ye-bottleneck ukuba bonke abaqulunqi abanako ukuyiphepha.
Ukusetyenziswa kwe-threonine kunokunciphisa inkunkuma yee-amino acids ezibalulekileyo nezingabalulekanga, okanye kunciphise izinga leprotheyini ekrwada yesondlo.Isizathu siyafana nokusetyenziswa kwe-lysine hydrochloride.Inqanaba leprotheyini ekrwada yesondlo inokufumaneka ngokusebenzisa i-crystalline amino acids.Ukunciphisa okunengqiqo, ukusebenza kwemveliso yezilwanyana akuyi konakaliswa, kodwa kunokuphuculwa.
