Incamake:Izina rya Tris ni tris (hydroxymethyl) aminomethane;tromethamine;tromethamine;2-amino-2- (hydroxymethyl) -1,3-propanediol.Ni kirisiti yera cyangwa ifu.Gushonga muri Ethanol n'amazi, gushonga gake muri Ethyl acetate na benzene, kudashonga muri ether na tetrachloride ya karubone, byangirika kumuringa na aluminium, hamwe nimiti irakaza.
Ibyerekana:Tromethamine ni sodium idafite amineri ya sodium, ifata H2CO3 mumazi yumubiri kugirango igabanye H2CO3 ikabyara HCO32- icyarimwe.Irashobora gukuramo ion ya hydrogène no gukosora aside.Komera, kandi irashobora kwinjira muri selile, ikunze gukoreshwa muri acide metabolike ikaze kandi ihumeka.
Ibikoresho byerekana:Tris ni ishingiro ridakomeye hamwe na pKa ya 8.1 kuri 25 ° C;ukurikije inyigisho ya buffer, urwego rukora neza rwa Tris buffer ruri hagati ya pH 7.0 na 9.2.PH yumuti wamazi wa Tris base ni 10.5.Mubisanzwe, hydrochloric aside yongeweho kugirango ihindure agaciro ka pH agaciro kifuzwa, hanyuma igisubizo cya buffer hamwe nigiciro cya pH kirashobora kuboneka.Ariko, hakwiye kwitonderwa ingaruka zubushyuhe kuri pKa ya Tris.
Gusaba:Tris ikoreshwa cyane muri acide metabolike ikaze hamwe nubuhumekero.Nibikoresho bya alkaline kandi bifite ingaruka nziza kuri acide metabolike nibikorwa bya enzymatique.Tris ikoreshwa kenshi nka bffer biologique kandi ikunze gukorwa hamwe na pH ya 6.8, 7.4, 8.0, na 8.8.Imiterere yimiterere nagaciro ka pH biratandukanye cyane nubushyuhe.Muri rusange Igitabo cya Shimi kivuga ko kuri buri cyiciro cyiyongera mubushyuhe, pH igabanuka 0,03.Tris ikoreshwa cyane mugutegura buffers mubushakashatsi bwibinyabuzima na biologiya.Kurugero, Tris irakenewe muri buffer zombi za TAE na TBE (kugirango solubilisation ya acide nucleic) ikunze gukoreshwa mubushakashatsi bwibinyabuzima.Kubera ko irimo itsinda rya amino, irashobora guhura na aldehydes.
