3. Lipid test要注意不同考局有区别：AQA考局不接受positive result描述为cloudy，只接受描述为milky，而Edexcel考局却接受cloudy的说法。这种细微的区别请考生们根据考局做个调整。4. 大部分考局不对Cellulose test做要求。文蓝IGCSE/A Level/IB辅导课程请私信规划君【guojijun01】了解，【数学、进阶数学、物理、...
蓝和黄=绿,黄+红=棕,所以从左(negative)到右(positive)分别是蓝(blue),绿(green),黄(yellow),棕(brown),红(brick-red)。 3. Lipid test要注意不同考局有区别:AQA考局不接受positive result描述为cloudy,只接受描述为milky,而Ed...

However, if the values of the standard Gibbs’ free energy are greater than −40 kJ mol−1, it is possible to conclude that the adsorption of an organic molecule at a solid surface is chemisorption, with the electronic distribution between the lone pair of organic molecules and the vacant...
In addition to the single biomolecules, interactions of molecules (Figure 7) are also able to produce significant effects on the functionality of larger-scale biomolecular complexes and tissues. DNA-protein interactions, which play important roles in numerous fundamental biological processes such as DNA...
