MuchidimbuTris brand name is tris(hydroxymethyl)aminomethane;tromethamine;tromethamine;2-amino-2- (hydroxymethyl) -1,3-propanediol.Ikristaro chena kana upfu.Soluble mu ethanol nemvura, inonyungudika zvishoma mu ethyl acetate ne benzene, isinganyunguriki mu ether uye carbon tetrachloride, inoora kusvika kumhangura nealuminium, uye makemikari anogumbura.
Zviratidzo:Tromethamine is sodium-isina amino buffer base, iyo inopindirana neH2CO3 mumvura yemuviri kuderedza H2CO3 uye kugadzira HCO32- panguva imwe chete.Inogona kutora hydrogen ions uye kugadzirisa acidemia.Yakasimba, uye inogona kupinda musero membrane, inowanzoshandiswa mune acute metabolic uye kufema acidemia.
Buffering zvivakwa:Tris inzvimbo isina simba ine pKa ye8.1 pa25 ° C;maererano nedzidziso yebuffer, iyo inoshanda buffering yeTris buffer iri pakati pepH 7.0 ne9.2.Iyo pH yeaqueous solution yeTris base inenge 10.5.Kazhinji, hydrochloric acid inowedzerwa kugadzirisa pH kukosha kune yaunoda kukosha, uye ipapo mhinduro yebuffer ine pH kukosha inogona kuwanikwa.Nekudaro, kutarisisa kunofanirwa kubhadharwa kune iyo tembiricha pane pKa yeTris.
Application:Tris inoshandiswa zvakanyanya muacute metabolic uye kufema acidemia.Iyo alkaline buffer uye ine yakanaka buffering maitiro pane metabolic acidosis uye enzymatic chiitiko.Tris inowanzo shandiswa sebiological buffer uye inowanzogadzirwa ine pH kukosha kwe6.8, 7.4, 8.0, uye 8.8.Yayo yemaitiro formula uye pH kukosha inosiyana zvakanyanya nekushisa.Kazhinji Chemicalbook inotaura kuti kune yega yega kuwedzera kwekushisa, iyo pH inoderera ne0.03.Tris inoshandiswa zvakanyanya mukugadzirira mabuffers mune biochemical uye molecular biology kuyedza.Semuyenzaniso, Tris inodiwa mune zvese TAE neTBE mabhafa (yekugadzirisa nucleic acids) inowanzoshandiswa mukuedza kwebiochemical.Sezvo iine boka remamino, inogona kuita condensation reactions nealdehydes.
