連二亞硫酸
英文
dithionite-
A new convenient synthesis of a series of polyfluoroalkyl substituted cyclopropane derivatives was achieved by the reaction of polyfluoroalkyl iodides with diethyl allylmalonate in the presence of sodium dithionite in 45 % ~ 55 % yields
摘要以連二亞硫酸鈉為引發劑，烯丙基丙二酸二乙酯與多氟烷基碘代烷在溫和條件下反應，方便地得到一系列多氟烷基取代的環丙烷衍生物，產率45 % ~ 55 % 。It is also strengthening its position in the hydrogen peroxide market. in the next few months, a new plant of sodium hydrosulphite and hydrogen peroxide in nansha, guangdong will be completed
集團並進一步鞏固本身在雙氧水市場的地位，在未來數月將有一家連二亞硫酸鈉保險粉及雙氧水廠在廣東南沙落成。One 66kd band appeared except 44kd main band when go isozyme above was subjected to sds - page and ce - sds, indicating this go isozyme was similar to that from spinach leaves which contained 40kd and 66kd simultaneously. whether b - mercaptoethanol was added or not when go isozyme was subjected to in sds - page and ce - sds, 40kd main band and 66kd band still appeared, indicating two subunits were not linked by covalent disulfide. amino acid analysis shew that the ratios of basic to acidic amino acid of go isozyme and its 40kd acidic subunit were 0
菜心go同工酶的sds - page和sds -毛細管電泳（ ce - sds ）顯示，該酶除了含40kd主帶外，還有很淺的66kd帶，和之前我們提出的菠菜go同工酶含40kd酸性亞基和66kd堿性亞基相似； sos - page和ce - sds電泳中，無論加入-巰基乙醇與否， go同工酶都只有40kd主帶和66kd淺帶，表明菜心go同工酶中40kd酸性亞基和66kd堿性亞基不是以共價二硫鍵相連；用制備性sds - page法獲得菜心go同工酶的40kd亞基，並和菜心go同工酶一起測定其氨基酸組成，該go同工酶及40kd亞基的堿酸性氨基酸的比例分別為0 . 66和0 . 54 ，表明40kd亞基可能是個酸性蛋白，而66kd帶則是個堿性蛋白。During the course of purification, the method of orthophenanthroline staining is used to detect the ferritin. 30 | il of the fractions eluted from the aca ^ gel column were pulled into the cells of the minim incubation plate. then sopil 20 % dithionite and 40 | il 0. 1 % orthophenanthroline solution were pulled into respectively
在酶標板小孔中加入30 l待測液，加入30 l20的連二亞硫酸鈉溶液還原后，再加入40 l0 . 1鄰菲咯啉溶液，根據有無桔紅色顏色產生確定是否含鐵蛋白。分享友人
