Nchịkọta:Akara aha Tris bụ tris (hydroxymethyl)aminomethane;tromethamine;tromethamine;2-amino-2- (hydroxymethyl) -1,3-propanediol.Ọ bụ kristal ọcha ma ọ bụ ntụ ntụ.Soluble na ethanol na mmiri, ntakịrị soluble na ethyl acetate na benzene, nke na-adịghị edozi na ether na carbon tetrachloride, na-emebi ọla kọpa na aluminom, na kemịkalụ na-akpasu iwe.
Ngosipụta:Tromethamine bụ ntọala amino nke na-enweghị sodium, nke na-emeghachi omume na H2CO3 n'ime mmiri ahụ iji belata H2CO3 wee mepụta HCO32- n'otu oge ahụ.Ọ nwere ike ịmịkọrọ ions hydrogen ma dozie acidemia.siri ike, ma nwee ike banye n'ime akpụkpọ ahụ cell, nke a na-ejikarị eme ihe na nnukwu metabolic na iku ume acidemia.
Njirimara nchekwa:Tris bụ ntọala adịghị ike nke nwere pKa nke 8.1 na 25 Celsius;dị ka usoro nchekwa nchekwa si dị, oke nchekwa nke Tris buffer dị n'etiti pH 7.0 na 9.2.pH nke ngwọta mmiri nke Tris base bụ ihe dịka 10.5.N'ozuzu, a na-agbakwunye hydrochloric acid iji mezie pH uru na uru achọrọ, mgbe ahụ enwere ike nweta ngwọta nchekwa nke nwere pH uru.Otú ọ dị, ekwesịrị ịṅa ntị na mmetụta nke okpomọkụ na pKa nke Tris.
Ngwa:A na-eji Tris eme ihe na nnukwu metabolic acidemia na akụkụ okuku ume.Ọ bụ ihe nchekwa alkaline ma nwee mmetụta dị mma na-ebufe na metabolic acidosis na ọrụ enzymatic.A na-ejikarị Tris eme ihe dị ka ihe nchekwa ndu ma na-ejikarị ụkpụrụ pH nke 6.8, 7.4, 8.0 na 8.8.Usoro nhazi ya na uru pH dị iche iche na ọnọdụ okpomọkụ.N'ozuzu Chemicalbook na-ekwu na maka ogo ọ bụla na-abawanye na okpomọkụ, pH na-ebelata site na 0.03.A na-eji Tris eme ihe n'ọtụtụ ebe na nkwadebe nke buffers na nyocha biochemical na molecular bayoloji.Dịka ọmụmaatụ, a chọrọ Tris na ma TAE na TBE buffers (maka solubilization nke nucleic acid) nke a na-ejikarị na nnwale biochemical.Ebe ọ nwere otu amino, ọ nwere ike nweta mmeghachi omume condensation na aldehydes.
