L-Histidine (H-His-OH) (CAS: 71-00-1) Shaqada Alaabta
1. L-Histidine waa amino acid lagama maarmaan ah oo aan samayn karin nafaqooyin kale, waana in ay ku jirtaa cuntada si uu jidhku u helo.
2. Inta badan waxaa loo aqoonsan yahay inay horudhac u yihiin calaamadaha xasaasiyadda ee soo saara hormoonka histamine, labadaba histidine iyo histamiin labaduba waxay leeyihiin door muhiim ah oo jirka ah oo ka baxsan dhibta xasaasiyadda.
3. Histamine waxaa si fiican loogu yaqaanaa doorka ay ku leedahay kicinta jawaab-celinta bararka ee maqaarka iyo xuubabka xuubka sida kuwa sanka laga helo - tallaabadani waxay lagama maarmaan u tahay ilaalinta caqabadahaas xilliga caabuqa.
4. Histamine waxa kale oo uu kiciyaa dheecaanka gastrin-ka ee dheefshiidka.Haddii aan la helin wax soo saar ku filan histamine dheef-shiid kiimikaadka caafimaadka qaba wuxuu noqon karaa mid daciifa.La'aanteed dukaamada L-histidine ku filan, jidhku ma ilaalin karo heerarka histamiin ku filan.
5. Waxa aan aad loo ogayn in L-histidine uu jidhku uga baahan yahay in uu habeeyo oo uu ka faa’iidaysto macdanaha raadraaca ee muhiimka ah sida copper, zinc, iron, manganese iyo molybdenum.
L-Histidine (H-His-OH) (CAS: 71-00-1) Isticmaalka
1. Kaabista nafaqada.Faleebo asiidh amino iyo diyaarinta amino acid dhamaystiran ayaa ah qaybo aad muhiim u ah.Caafimaad ahaan, waxa lagu daweeyaa boogaha caloosha, dhiig-yarida, xasaasiyadda, iwm. Waxa loo isticmaalaa cilmi-baadhista biochemical iyo dawooyinka daawaynta boogaha caloosha, dhiig-yarida, xasaasiyadda, iwm.
2. Daawooyinka Amino Acid.Qaybaha ugu muhiimsan ee faleebo amino acid ah iyo diyaarinta amino acid dhamaystiran ayaa loo isticmaalaa in lagu daaweeyo cudurrada wadnaha iyo xididada sida boogaha gastric, dhiig-yaraan, angina pectoris, arteritis iyo ku filnaansho la'aanta wadnaha.
3. Waa qayb muhiim ah oo ka mid ah faleebada amino acid iyo diyaarinta amino acid ka kooban.Waxaa loo isticmaali karaa in lagu daweeyo boogaha caloosha.Waxa kale oo loo isticmaalaa cilmi-baarista biochemical.
4. Loo isticmaalo sidii alaabta ceeriin ee dawooyinka iyo cuntada lagu daro.
