The regeneration of NAD(P)H can be achieved via catalysis, but the unequivocal determination of the species involved has not yet been fully realized. The current analytical methods of reactant/product analysis based on UV-vis spectroscopy, enzymatic assays, NMR spectroscopy, and HPLC are critically examined here with suggestions for future development.

辅因子NAD（P）H再生：反应的选择性如何？

NAD（P）H的再生可通过催化来实现，但尚未完全明确地确定所涉及的物种。本文对目前基于紫外线-可见光谱，酶法测定，NMR光谱和HPLC的反应物/产物分析的分析方法进行了严格审查，并提出了对未来发展的建议。
