Nānā nui:ʻO ka inoa inoa ʻo Tris ʻo tris(hydroxymethyl)aminomethane;tromethamine;tromethamine;2-amino-2-(hydroxymethyl) -1,3-propanediol.He aniani keʻokeʻo a pauda paha.Hiki ke hoʻoheheʻe ʻia i loko o ka ethanol a me ka wai, hiki ke hoʻoheheʻe ʻia i ka ethyl acetate a me benzene, hiki ʻole ke hoʻoheheʻe ʻia i ka etera a me ka carbon tetrachloride, corrosive i ke keleawe a me ka alumini, a me nā mea hoʻonāukiuki.
Nā hōʻailona:ʻO Tromethamine kahi kumu paʻa amino paʻa ʻole sodium, e hana pū me H2CO3 i loko o nā wai kino e hōʻemi i ka H2CO3 a hoʻoulu i ka HCO32- i ka manawa like.Hiki iā ia ke komo i nā ion hydrogen a hoʻoponopono i ka acidemia.ʻO ka ikaika, a hiki ke komo i ka membrane cell, maʻamau i hoʻohana ʻia i ka maʻi metabolic a me ka acidemia hanu.
Nā waiwai pale:ʻO Tris kahi kumu nāwaliwali me kahi pKa o 8.1 ma 25 ° C;e like me ke kumumanaʻo buffer, ʻo ka pae hoʻopono kūpono o Tris buffer ma waena o pH 7.0 a me 9.2.ʻO ka pH o ka hopena wai o Tris base ma kahi o 10.5.ʻO ka maʻamau, hoʻohui ʻia ka waika hydrochloric e hoʻoponopono i ka waiwai pH i ka waiwai i makemake ʻia, a laila hiki ke loaʻa ka hopena buffer me ka waiwai pH.Eia naʻe, pono e nānā i ka hopena o ka mahana ma ka pKa o Tris.
Noi:Hoʻohana nui ʻia ʻo Tris i ka metabolic acute a me ka acidemia respiratory.He paʻa alkaline a he hopena hoʻopaʻa maikaʻi i ka metabolic acidosis a me ka hana enzymatic.Hoʻohana pinepine ʻia ʻo Tris ma ke ʻano he biological buffer a hana pinepine ʻia me nā waiwai pH o 6.8, 7.4, 8.0, a me 8.8.ʻOkoʻa loa kona ʻano kumu a me ka waiwai pH me ka mahana.Wahi a Chemicalbook maʻamau, no kēlā me kēia degere ka piʻi ʻana o ka mahana, emi ka pH ma 0.03.Hoʻohana nui ʻia ʻo Tris i ka hoʻomākaukau ʻana i nā buffers i nā hoʻokolohua biochemical a me ka molecular biology.No ka laʻana, koi ʻia ʻo Tris i loko o ka TAE a me TBE buffers (no ka solubilization o nucleic acids) i hoʻohana mau ʻia i nā hoʻokolohua biochemical.No ka loaʻa ʻana o kahi hui amino, hiki iā ia ke hana i nā hopena condensation me nā aldehydes.
