Clau (5, 10, 20〓) was bound to rat plasma a greater extent than clau, while in rabbit plasma the reverse was the case. By Scatchard plots using bovine serum albumin, clau had a higher equilibrium constant and the greater numbers of binding sites than its antipode.

在与大鼠血浆蛋白的结合中，clau的结合率平均为28.37±0.31（n=3，三个剂量5，10，20μM），clau的结合率平均为38.05±2.61（n=3），clau结合率低于clau；而在与兔血浆蛋白的结合中，clau的结合率平均为47.21±4.91（n=3，三个剂量），clau的结合率平均为41.43±5.21（n=3），clau的结合率略高于clau；在与牛血清白蛋白的结合中，clau的结合率也高于clau，立体选择方向与兔血浆蛋白结合相同，而与大鼠血浆蛋白结合相反，提示存在种属差异；在与系列浓度的牛血清白蛋白结合中，通过Scatchard作图法求得蛋白结合点数和平衡常数；在clau，N和K分别为90.02±35.76和5.326±1.196（n=4）；在clau，N和K分别为59.92±20.39和4.203±1.250（n=4），两者的比值分别为1.50和1.27；进一步说明clau对映体的蛋白结合存在立体选择性差异。

When bottom object concentration is 6-12g/L, different mole ratio cyclodextrin is added according to different bottom object, the percent conversion of bottom object aromatic ketone is 50-99and antipode excess value of outcome optically active alcohol is 75-99D:工作文件发明补译2433biba_补13_sunquansheng(100件)2433biba_补13_sunquansheng(100件).txto the product incorporating the invention has high practical application worthiness.

利用本发明在底物浓度为6～12g/L时，环糊精用量根据底物的不同选择不同的摩尔比加入，此时底物芳香酮的转化率为50％～99％，产物光学活性醇的对映体过量值为75％～99％，具有较高的实际应用价值。
