Tirohanga:Ko te ingoa tohu Tris ko te tris(hydroxymethyl)aminomethane;tromethamine;tromethamine;2-amino-2-(hydroxymethyl) -1,3-propanediol.He karaihe ma, he paura ranei.He wairewa ki te waiwaro me te wai, paku wairewa ki te ethyl acetate me te benzene, kare e rewa i roto i te etera me te waro tetrachloride, te pirau ki te parahi me te konumohe, me nga matū whakariri.
Tohu:Ko te Tromethamine he turanga parapara amino-kore konutai, e tauhohe ana ki te H2CO3 i roto i nga wai o te tinana hei whakaiti i te H2CO3 me te whakaputa HCO32- i te wa ano.Ka taea e ia te tango i nga katote hauwai me te whakatika i te waikawa.He kaha, ka taea te uru ki roto i te kiriuhi o te pūtau, e whakamahia nuitia ana i roto i te mate whakapeka metabolic me te waikawa rewharewha.
Āhuatanga Buffering:He turanga ngoikore a Tris me te pKa 8.1 i te 25°C;e ai ki te ariā buffer, kei waenga i te pH 7.0 me te 9.2 te awhe buffering whai hua o Tris buffer.Ko te pH o te wairewa wai o te turanga Tris he 10.5 pea.Ko te tikanga, ka taapirihia te waikawa maaota ki te whakatika i te uara pH ki te uara e hiahiatia ana, katahi ka taea te whiwhi i te otinga parepare me te uara pH.Engari, me aro ki te paanga o te pāmahana ki te pKa o Tris.
Taupānga:Kei te whakamahia nuitia a Tris mo te mate huka me te waikawa rewharewha.He parepare kawakore, he pai te whakaahuru ki te waikawa metabolic me te mahi enzymatic.He maha nga wa e whakamahia ana a Tris hei parenga koiora me te hanga i nga uara pH o 6.8, 7.4, 8.0, me te 8.8.He rereke te ahua o tana hanganga me te uara pH ki te pāmahana.I te nuinga o te korero a Chemicalbook mo ia pikinga tohu o te pāmahana, ka heke te pH ma te 0.03.Kei te whakamahia nuitia a Tris ki te whakareri i nga parepare i roto i nga whakamatautau koiora matū me te koiora.Hei tauira, e hiahiatia ana a Tris i roto i nga parepare TAE me te TBE (mo te whakamaaramatanga o nga waikawa karihi) e whakamahia nuitia ana i roto i nga whakamatautau matū koiora.I te mea he roopu amino kei roto, ka taea e ia te uru ki nga tauhohenga whakaahuru me te aldehydes.
