I-DL-Methionine (H-DL-Met-OH) (i-CAS: 59-51-8) ingenye yamayunithi ayisisekelo wokwenza amaprotheni, iyona kuphela isibabule esine-amino acid phakathi kwama-amino acid abalulekile, ibambe iqhaza I-transmethylation yangaphakathi yomzimba wesilwane, i-phosphorus metabolism kanye ne-adrenalin, i-choline kanye ne-creatine synthesis, futhi iyimpahla eluhlaza yamaprotheni kanye ne-cystine synthesis.I-Methionine ayikwazi ukuhlanganiswa emzimbeni wesilwane, kufanele ithathwe ekudleni.Ukuyengeza ekudleni, kungakhuthaza izinkukhu ukuthi zikhule, kwandise ubuningi benyama enomzimba omncane futhi kunciphise umjikelezo wokuphakela.
Ukusetshenziswa kwe-Dl-Methionine
{Ibanga lokuphakelayo}
Isengezo sokudla kwezilwane emfuyweni sitholakala nge-DL-Methionine kanye ne-zinc sulphat.
1. Okubangelwa ukusabela kwemvukuzane ye-zinc ion kuma-moles e-methionine, amaphesenti aphezulu e-chelate, ukuzinza okukhulu kakhulu.
2. I-bioavailability ephezulu, umsoco ongcono we-zinc, uhlobo lwesithako esingcono sokuphakelayo.
3. Ungathintwa inani le-pH, ama-ion e-inorganic kanye nama-organic macromolecules emgudwini wokugaya ukudla.
Umsebenzi womkhiqizo
Yengezwa ekudleni kwezilwane, i-DL-Methionine ingasiza izilwane zikhule ngokushesha ngesikhathi esifushane futhi cishe u-40% wokudla kwazo ungagcinwa.
1. I-bioavailability yesithasiselo sokudla kwezilwane emfuyweni ingcono kakhulu kunezinye i-organic zinc.
2. Xazulula inkinga yokuqhekeka kwenselo ezinsikazini ngendlela efanele.
3. Khulisa izinga lokuzalela, ukuvundiswa, kanye nokuchanyuselwa, uthuthukise izinga legobolondo leqanda.
4. Kuholela ekukhishweni kophaphe olumahhadlahhadla nolungcolile, kutholwe uphaphe olukhanyayo.Futhi ukwehla kwe-cannib alism yokucofa i-plume ne-anus.
5. Ukwandisa ukudla okudliwayo ngempumelelo, kungathuthukisa ukukhula kwezilwane kanye nokumelana nezifo, kukhuthaze umsoco owengeziwe.
6. Le-zinc methionine ingenza izilwane zikhule.
{Ibanga Lokudla}
I-DL-Methionine ingenye yama-amino acid ayi-18 ajwayelekile, futhi ingenye yama-amino acid ayisishiyagalombili abalulekile esilwaneni nasemzimbeni womuntu.Isetshenziswa kakhulu njengezithasiselo zokudla ezinhlanzini, ezinkukhuni, ezingulubeni nasezinkomeni ukuze kugcinwe izilwane nezinyoni zikhula ngendlela enempilo.Kungathuthukisa ukukhiqizwa kobisi lwezinkomo, kuvimbele ukuvela kwe-hepatosis.Ngaphandle kwalokho, ingasetshenziswa futhi njengemithi ye-amino acid, isixazululo somjovo, ukumnika okunomsoco, i-ejenti yesibindi esivikelayo, ukwelashwa kwe-cirrhosis yesibindi kanye ne-hepatitis enobuthi.
1. I-DL-Methionine ingasetshenziswa ekuhlanganiseni amavithamini ezokwelapha, izithasiselo zokudla okunomsoco kanye nezithasiselo zokudla.
2. I-DL-Methionine ingenye yezingxenye eziyinhloko zokufakwa kwe-amino acid kanye ne-amino acid ehlanganisiwe.I-DL-Methionine ine-anti-fatty function yesibindi.Ngokusebenzisa leli thuba, amavithamini emithi yokwenziwa angasetshenziswa njengamalungiselelo okuvikela isibindi.
3. Njenge-amino acid ebalulekile yomzimba womuntu, i-DL-Methionine ingasetshenziswa njengesengezo sokudla okunomsoco ekucutshungulweni kokudla kanye nokulondoloza okufana nemikhiqizo yekhekhe lezinhlanzi.
4. Njengengxenye ebalulekile ekuhlanganiseni kwamaprotheni, i-DL-Methionine inomphumela wokuvikela emisipha yenhliziyo.Ngesikhathi esifanayo, i-DL-Methionine ingashintshwa ibe yi-taurine ngesulfure, kuyilapho i-Taurine inomphumela ocacile we-hypotensive.I-DL-Methionine nayo inomsebenzi omuhle wokuvikela isibindi kanye nokukhipha ubuthi emzimbeni, ngakho-ke ivame ukusetshenziswa ekwelapheni izifo zesibindi ezifana ne-cirrhosis, isibindi esinamafutha kanye ne-hepatitis yegciwane eyingozi futhi engapheli.Inomphumela omuhle kakhulu.
5. I-DL-Methionine ingasetshenziswa njengesengezo senutional.I-DL-Methionine inomphumela ofanayo ne-L-Methionine, kodwa i-DL-Methionine ishibhile.
6. I-DL-Methionine ingakhiwa njenge-agent yokunambitheka.
7. I-DL-Methionine iyisithuthukisi sokudla okunomsoco.Ukushoda kweMethionine kwemfuyo nezinkukhu, kungaholela ekukhuleni okunciphile, ukuncipha, ukuncipha kokusebenza kwesibindi nezinso, imisipha ye-muscle, uboya, i-metamorphism nokunye.Engeza i-1 kg ye-methionine, ukudla okunomsoco wezinhlanzi ezingu-50 kg.Okuphakelayo kokuqukethwe okuvamile okungu-0.05% kuya ku-0.2%.
