| nkwadebe | tinye 50mL nke L-Thr (30mmol) wee mee ka mmiri Na2CO3 juputara n'ime karama mmeghachi omume 250mL, ma kpalie ma gbazee na bat ice. Wepu 20ml nke Z-OSu (39.4mmol) acetone ngwọta n'ime karama mmeghachi omume; Mee ka mmeghachi omume na 25 ℃, TLC-UV fluorescence na ninhydrin agba usoro nyochaa usoro mmeghachi omume. Mgbe mmeghachi omume ahụ gasịrị, gbakwunye H2O20mL, wepụ ya na Et2O (30mL × 2) na pH> 9, na-anakọta usoro mmiri, gbanwee pH na 3 ~ 4 na 1.5NHCl, wepụ ya na EtOAc (30mL × 3), jikọta usoro nke organic, saa ya na ngwọta NaCl juru eju (25mL × 2), kpoo ya na mmiri Na2SO4 na-ekpo ọkụ, lelee ịdị ọcha site na TLC-ultraviolet fluorescence na ninhydrin agba mmepe usoro, na evaporate n'okpuru belatara nrụgide, agụụ ihicha iji nweta a-acha mmanu mmanu mmiri N-benzyloxycarbonyl-L-threonine, nke echekwara na obere okpomọkụ. |
| Jiri | CBZ-L-threonine bụ N-Cbz na-echebe ụdị L-threonine (T405500). L-threonine bụ amino acid dị mkpa ma na-ejikarị eme ihe dị ka nri na mgbakwunye nri. Udiri mutant nke Escherichia coli mepụtara L-threonine buru ibu maka ebumnuche nyocha na nri nri. A na-ahụkarị L-threonine na azụ na anụ ọkụkọ ma tinye ya na ụfọdụ protein dị mkpa nke ahụ, dị ka hemoglobin na insulin. A na-eji ya maka reagents biochemical na njikọ peptide. |
