L-Histidine (H-His-OH) (CAS: 71-00-1) Umsebenzi weMveliso
1. I-L-Histidine iyimfuneko ye-amino acid engenakwenziwa ngezinye izondlo, kwaye kufuneka ibe ekudleni ukuze ifumaneke kumzimba.
2. Ubukhulu becala bubonwa njengesandulela seempawu zokungalungelani nokwaliwa ezivelisa ihomoni ye-histamine, zombini i-histidine kunye ne-histamine zinendima ebalulekileyo emzimbeni ngaphaya kokungcungcuthekisa abantu abane-allergies.
3. I-Histamine iyaziwa kakhulu ngendima yayo ekukhuthazeni impendulo yokuvuvukala kwesikhumba kunye neembrane ze-mucous ezifana nezo zifunyenwe empumlweni - esi senzo siyimfuneko ekukhuseleni le miqobo ngexesha losulelo.
4. I-Histamine iphinda ikhuthaze ukukhuselwa kwe-enzyme yokugaya i-gastrin.Ngaphandle kwemveliso eyaneleyo ye-histamine, ukugaya okunempilo kunokonakala.Ngaphandle kweevenkile ze-L-histidine ezaneleyo, umzimba awukwazi ukugcina amanqanaba afanelekileyo e-histamine.
5. Okungaziwa kakhulu kukuba i-L-histidine ifunwa ngumzimba ukulawula kunye nokusetyenziswa kweeminerali ezibalulekileyo ezifana nobhedu, i-zinc, isinyithi, i-manganese kunye ne-molybdenum.
L-Histidine (H-His-OH) (CAS: 71-00-1) Ukusetyenziswa
1. Izongezo zesondlo.Ukufakwa kwe-amino acid kunye nokulungiswa okubanzi kwe-amino acid zizinto ezibaluleke kakhulu.Ngokwezonyango, isetyenziselwa ukunyanga isilonda esiswini, i-anemia, i-allergies, njl. Isetyenziselwa uphando lwe-biochemical kunye neyeza lokunyanga i-gastric ulcer, i-anemia, i-allergies, njl.
2. Iziyobisi ze-amino acid.Amacandelo aphambili okufakwa kwe-amino acid kunye nokulungiswa okubanzi kwe-amino acid asetyenziselwa ukunyanga izifo zentliziyo ezifana nesilonda sesisu, i-anemia, i-angina pectoris, i-arteritis kunye nokusilela kwentliziyo.
3. Iyinxalenye ebalulekileyo ye-amino acid infusion kunye nokulungiswa kwe-amino acid edibeneyo.Ingasetyenziselwa ukunyanga isilonda esiswini.Ikwasetyenziswa kuphando lwe-biochemical.
4. Isetyenziswa njengezinto ezikrwada zamayeza kunye nezongezo zokutya.
