可可碱对胰α-淀粉酶的抑制类型及光谱性质的影响
The Partial Influence of Theobromine on Pancreatic Amylase
【摘要】 运用紫外光谱和荧光光谱技术研究可可碱与胰α-淀粉酶的结合。反应类型为非竞争性抑制。Ki值为0.72×10-2mol/L。根据Stern-Volmer方程,计算了可可碱对胰α-淀粉酶的表观淬灭常数,推测其荧光影响可能属于静态淬灭机制。
【Abstract】 By using ultraviolet and fluorescent spectrometry,we studied the relation between theobromine and pancreatic amylase.The reaction in this research was investigated.The Ki was 0.72×10-2 mol/L.According to the Stern-Volmer equations,we computed the expressing quench parameter of pancreatic amylase influenced by theobromine.We guess that the underlying mechanism belongs to static quench.
