生物制备1,6-二磷酸果糖(FDP)的研究进展

1．6-二磷酸果糖是一种性质活泼的天然高能化合物，是糖代谢的中间代谢产物，具有激活糖代谢中若干酶活性之功效，在医学、食品、保健品、化妆品上具有广阔的应用前景．利用酶使葡萄糖或蔗糖磷酸化制备YDP，通过沉淀、转型、离子吸附、洗脱、结晶来提取精制YDP．本文对YDP近年来的研究应用进展进行了综述．     

应选哪个量程

同学们都知道，实验室常用的电流表有0～0．6A和0～3A两个量程；电压表有0～3V和0～15V两个量程．实验时，应先通过估算或试触来正确选择量程．电流表量程的选择：如果电路中的电流I＜O．6A时．可选用0～0.6A量程来测量；如果）6A＜I＜3A时，可选用O～3A量程来测量；如果I＞3A时，不能用此表来测量．电压表量程的选择：若被测导体两端的电压U＜3V时．可选用O～3V量程来测量；若3V＜U＜15V时，可选用0～15V量程来测量；若U＞15V时，就不能用此表来测量．那么在下题中应选用电流表和电压表的哪个量程呢？【题目〕如图所示，R。是0…

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
