I-L-Histidine (H-His-OH) (CAS: 71-00-1) Umsebenzi Womkhiqizo
1. I-L-Histidine iyi-amino acid ebalulekile engakwazi ukwakhiwa ezinye izakhi, futhi kufanele ibe ekudleni ukuze itholakale emzimbeni.
2. Okuvame ukubonwa njengesandulela sophawu lokwaliwa olukhiqiza ihomoni i-histamine, kokubili i-histidine ne-histamine zinezindima ezibalulekile emzimbeni ngaphezu kokuhlukumeza abantu abangezwani nabo.
3. I-Histamine yaziwa kakhulu ngendima yayo ekukhuthazeni ukusabela kokuvuvukala kwesikhumba kanye nolwelwesi lwamafinyila njengalawo atholakala emakhaleni - lesi senzo sibalulekile ekuvikelweni kwalezi zithiyo ngesikhathi sokutheleleka.
4. I-histamine iphinde ikhuthaze ukukhishwa kwe-enzyme yokugaya i-gastrin.Ngaphandle kokukhiqizwa kwe-histamine okwanele ukugaya okunempilo kungaphazamiseka.Ngaphandle kwezitolo ezanele ze-L-histidine, umzimba awukwazi ukugcina amazinga e-histamine anele.
5. Okungaziwa kakhulu ukuthi i-L-histidine idingwa umzimba ukuze ulawule futhi usebenzise amaminerali abalulekile afana nethusi, i-zinc, insimbi, i-manganese ne-molybdenum.
I-L-Histidine (H-His-OH) (CAS: 71-00-1) Ukusetshenziswa
1. Izithako zokudla okunomsoco.Ukufakwa kwe-amino acid kanye nokulungiswa okuphelele kwe-amino acid kuyizingxenye ezibaluleke kakhulu.Ngokwemithi, isetshenziselwa ukwelapha isilonda esiswini, i-anemia, i-allergies, njll. Isetshenziselwa ucwaningo lwe-biochemical kanye nemithi yokwelapha isilonda sesisu, i-anemia, i-allergies, njll.
2. Izidakamizwa ze-amino acid.Izingxenye eziyinhloko zokumnika kwe-amino acid kanye nokulungiswa okuphelele kwe-amino acid kusetshenziselwa ukwelapha izifo zenhliziyo ezifana ne-gastric ulcer, i-anemia, i-angina pectoris, i-arteritis kanye nokungakwazi kwenhliziyo.
3. Kuyingxenye ebalulekile yokufakwa kwe-amino acid kanye nokulungiswa kwe-amino acid ehlanganisiwe.Ingasetshenziselwa ukwelapha isilonda esiswini.Ibuye isetshenziswe ocwaningweni lwe-biochemical.
4. Isetshenziswa njengezinto zokusetshenziswa kwemithi kanye nezithasiselo zokudla.
