Isicelo:

I-DL-Methionine (i-H-DL-Met-OH) (i-CAS: i-59-51-8) yenye yeeyunithi ezisisiseko zokuqulunqa iprotheni, yi-sulfure kuphela ephethe i-amino acid phakathi kwee-amino acids ezibalulekileyo, yathatha inxaxheba kwi-amino acid. I-transmethylation yangaphakathi kumzimba wesilwanyana, i-phosphorus metabolism kunye ne-adrenalin, i-choline kunye ne-creatine synthesis, nayo iyimpahla ekrwada yeprotheni kunye ne-cystine synthesis.I-methionine ayikwazi ukudibanisa kumzimba wesilwanyana, kufuneka ithathe ukutya.Yongeza kwisondlo, inokukhuthaza inkuku ukuba ikhule, yandise ubuninzi benyama ebhityileyo kunye nokunciphisa umjikelo wokutya.
Ukusetyenziswa kwe-Dl-Methionine
{Ibanga lokutyisa}
Isondlo sezilwanyana esongezelelweyo kwimfuyo sichetywa nge-DL-Methionine kunye ne-zinc sulphat.
1. Okubangelwa ukusabela kwe-mole ye-zinc ion kwi-moles ye-methionine, ipesenti ephezulu ye-chelate, ukuzinza okukhulu.
2. I-bioavailability ephezulu, isondlo esingcono se-zinc, luhlobo lwe-additive feed engcono.
3. Musa ukuchaphazeleka ngexabiso le-pH, i-ion ye-inorganic kunye ne-organic macromolecules kwi-digestive tract.
Umsebenzi wemveliso
Yongezwa kwisondlo sezilwanyana, i-DL-Methionine inokunceda izilwanyana zikhule ngokukhawuleza ngexesha elifutshane kwaye malunga ne-40% yokutya kwazo kunokugcinwa.
1. I-bioavailability yesondlo sezilwanyana esongezelela imfuyo ngcono kakhulu kunezinye i-organic zinc.
2. Sombulula kakuhle ingxaki yokuqhekeka kwempuphu kwiimazi.
3. Yandisa izinga lokuzala, ukuchumisa, kunye nokuqandusela, phucula umgangatho weqokobhe leqanda.
4. Ikhokelela ekususweni kwentsiba erhabaxa kunye nemdaka, ukufumana intsiba eqaqambileyo.Kwaye ukuncipha kwi-cannib alism yokugqogqa iplamu kunye ne-anus.
5. Ukwandisa ukutya ngokufanelekileyo, kunokuphucula ukukhula kwezilwanyana kunye nokumelana nezifo, ukukhuthaza ukutya okuninzi.
6. Le zinc methionine inokongeza kwizilwanyana ezingenazo izondlo ezisempilweni, inokwenza ukuba izilwanyana zikhule.
{Ibanga lokutya}
I-DL-Methionine yenye yee-amino acids ze-18 eziqhelekileyo, kwaye enye ye-amino acids ezisibhozo ezibalulekileyo kwisilwanyana kunye nomzimba womntu.Isetyenziswa kakhulu njengezongezo zokutya kwintlanzi, iinkukhu, iihagu kunye nesidlo senkomo ukuze kugcinwe izilwanyana kunye neentaka zikhula ngokusempilweni.Ingaphucula ukukhuselwa kobisi lweenkomo, ithintele ukwenzeka kwe-hepatosis.Ngaphandle koko, isenokusetyenziswa njengamayeza e-amino acid, isisombululo senaliti, ukufakwa kwesondlo, i-arhente ekhuselayo yesibindi, unyango lwe-cirrhosis yesibindi kunye ne-hepatitis enetyhefu.
1. I-DL-Methionine ingasetyenziselwa ukuhlanganiswa kweevithamini zonyango, izongezo zesondlo kunye nezongezo zokutya.
2. I-DL-Methionine yenye yezinto eziphambili ze-amino acid infusion kunye ne-compound amino acid.I-DL-Methionine ine-anti-fatty function yesibindi.Ukuthatha inzuzo yalo msebenzi, iivithamini zamayeza okwenziwa zingasetyenziswa njengamalungiselelo okukhusela isibindi.
3. Njengoko i-amino acid ebalulekileyo yomzimba womntu, i-DL-Methionine ingasetyenziselwa njengesongezelelo sesondlo sokutya kunye nokugcinwa kokugcinwa kwezinto ezifana neemveliso zekhekhe zeentlanzi.
4. Njengenxalenye ebalulekileyo kwiprotheni synthesis, i-DL-Methionine inefuthe lokukhusela kwi-heart muscle.Ngelo xesha, i-DL-Methionine inokuguqulwa ibe yiTaurine ngesulfure, ngelixa i-Taurine inefuthe elicacileyo kakhulu le-hypotensive.I-DL-Methionine nayo inomsebenzi omhle wokukhusela isibindi kunye nokuchithwa kwe-detoxification, ngoko isetyenziswa ngokuqhelekileyo kunyango lwezonyango lwezifo zesibindi ezifana ne-cirrhosis, isibindi esinamafutha kunye ne-hepatitis yentsholongwane eyingozi kunye nengapheliyo.Inesiphumo esihle kakhulu.
5. I-DL-Methionine ingasetyenziselwa njengezongezelelo ze-nutional.I-DL-Methionine inesiphumo esifanayo ne-L-Methionine, kodwa i-DL-Methionine inexabiso eliphantsi.
6. I-DL-Methionine inokuqulunqwa njenge-agent ye-flavoring.
7. I-DL-Methionine sisixhasi sesondlo sokutya.Imfuyo kunye neenkukhu ukungabikho kweMethionine, kunokukhokelela ekukhuleni okungahambi kakuhle, ukunciphisa umzimba, isibindi kunye nokusebenza kwezintso, i-muscle atrophy, uboya, i-metamorphism njalo njalo.Yongeza i-1 kg ye-methionine, ukutya kwe-50 kg yexabiso lesondlo sentlanzi.Ukutya kumxholo jikelele we-0.05% ukuya kwi-0.2%.
