Izakhiwo Zomzimba Nezamakhemikhali IHydrochloride imhlophe noma i-hydrochloride icishe ibe yimpushana emhlophe, engenaphunga, enambithekayo ebabayo. 218 C lapho kubhakwa, 225 C lapho isimo esiqinile. Iphuzu lokuncibilika 235 °c (ukubola). Incibilika emanzini, incibilika ku-ethanol eshisayo, ayincibiliki ku-ether.
Sebenzisa I-Arginine iyi-amino acid ebalulekile ekukhuleni nasekuthuthukisweni kwezinsana nezingane ezincane. Kuyi-metabolite ephakathi yomjikelezo we-ornithine okhuthaza ukuguqulwa kwe-ammonia ku-urea, ngaleyo ndlela kunciphise amazinga e-ammonia egazini. Kubuye kube ingxenye eyinhloko yephrotheni yesidoda, ekhuthaza ukukhiqizwa kwesidoda futhi inikeza amandla okunyakaza kwesidoda. Ngaphezu kwalokho, i-arginine emithanjeni, ingashukumisa ukukhululwa kwe-hormone yokukhula kwe-pituitary, ingasetshenziselwa ukuhlolwa komsebenzi we-pituitary.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amakhodi Engozi R36 – Ukucasuka emehlweni
R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile.
U-R61 - Ingabangela ukulimala enganeni engakazalwa
Incazelo Yokuphepha I-S24/25 - Gwema ukuthintana nesikhumba namehlo.
S36 – Gqoka izingubo ezifanele zokuzivikela.
S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.)
S53 – Gwema ukuchayeka – thola imiyalelo ekhethekile ngaphambi kokuyisebenzisa.
S39 – Gqoka ukuvikela iso / ubuso.

Isingeniso

I-substrate ye-nitric oxide synthetase eguqulelwa ku-citrulline ne-nitric oxide (NO). Ukukhishwa kwe-insulin kubangelwa indlela ehambisana ne-nitric oxide.
