求翻译：在做叶酸与壳聚糖的偶联实验时，必须使用大量的有机试剂和有毒的偶联试剂，残留的偶联试剂势必对机体造成细胞毒性以及对大分子产生灭活是什么意思？

In doing folic acid and chitosan coupling experiments must use a lot of toxic organic reagents and coupling reagents, the residual coupling reagent is bound to cause cell toxicity and the body produces molecules inactivated

Done in folic acid and chitosan the coupling experiments must be used when large numbers of organic reagents and toxic coupling reagents, remnants of coupling reagents is bound to cause cellular toxicity and organism of large molecules have inactivated

When will make the folic acid and the shell polyose coupling experiment, must use the massive organic reagents and the virulent coupling reagent, the residual coupling reagent will inevitably create the cell toxicity to organism as well as has the deactivation to the macro-molecule

In folic acid and Chitosan coupling experiments, you must use a large number of coupling of organic reagent and toxic reagents, residue coupling reagents are set on the body causing the cytotoxicity and inactivated on macromolecular

While making folic acid and shell and gathering uniting the experiment occasionally of the candy, must use a large amount of organic reagent and poisonous uniting reagent occasionally, the residual uniting reagent occasionally certainly will cause the cell toxicity and deactivate the macromolecule t
