Umlingiswa
I-crystal emhlophe noma i-crystalline powder.Incibilika emanzini, ayincibiliki ku-methanol, ethanol ne-ether.Ingadonswa kusukela kusisombululo sayo esigxilile nge-phosphotungstic acid futhi isabelane nesisombululo se-alkali esigxilile ukuze senze i-ornithine, i-carbon dioxide ne-ammonia.Usawoti wethusi uyikristalu eluhlaza okwesibhakabhaka yeprismatic enephuzu lokuncibilika elingu-257-258℃.Iphuzu elincibilikayo le-hydroxide yayo, i-Chemicalbook185 ° C (ukubola), ingu +17.9° emanzini [α]D22.Itholakala emakhabeni afana namakhabe.Kubantu, i-citrate i-nonprotein amino acid engahlanganyeli ekuhlanganiseni amaprotheni, kodwa inamandla okwenza izibopho ze-peptide.Ngaphambilini kwakucatshangwa ukuthi ikhona kuphela njengomkhiqizo ophakathi we-ornithine - urea cycle.
Izakhiwo Zekhemikhali: I-crystalline powder emhlophe, encibilika ku-methanol, i-ethanol, i-DMSO nezinye izincibilikisi eziphilayo, ezivela ku-trichosanthin.
Sebenzisa:1.L-uhlobo lwe-arginine lulungiswe njengesiphakathi se-NOx nge-NO synthase
2.Imiphumela emikhulu ye-citrulline L-citrulline:
Imisebenzi Esemqoka
1. Thuthukisa amasosha omzimba.
2. gcina umsebenzi wokuhamba ngokuhlanganyela.
3. Linganisa amazinga avamile kashukela egazini.
4. ukumuncwa okune-antioxidant kwama-radicals mahhala e-Chemicalbook ayingozi.
5. Isiza ukugcina amazinga e-cholesterol ejwayelekile.
6. Gcina ukusebenza kwamaphaphu e-Jiankang
7. Thuthukisa ukucaca kwengqondo
Yehlisa ukucindezeleka futhi unqobe ukucindezeleka
9. thuthukisa umsebenzi wempilo yocansi we-jiankang
Ukusebenza Nokusebenza: I-Citrulline iyi-amino acid engeyona iprotein enekhono lokwenza amabhondi e-peptide kodwa ayihlanganyeli ekuhlanganiseni amaprotheni.I-Citrulline yake yabhekwa njengomkhiqizo omaphakathi womjikelezo we-urea we-Chemicalbook ring.Kodwa-ke, ucwaningo lwakamuva lubonise ukuthi i-citrulline ingasetshenziswa kabanzi kwezokwelapha, ukudla, ukunakekelwa kwezempilo nezinye izici, futhi inemiphumela emihle yemithi.
