transmembrane electron transport to the internal acceptor, K3[Fe(CN)6] through the flavolipid (1) was observed. BzNAHCOOK was proved to be an appropriate NADH model in the transmembrane electron transport study because of (i) the very low permeability through the bilayer membrane (k=1.0×10−3 s−1) and (ii) the slow hydration rate (k=1.1×10−5 s−1). The artificial liposome modified with the flavolipid showed a 6–7
通过在外部电子供体中使用强亲水性 NADH 模型 BzNAHCOOK,观察到跨膜电子传输到内部受体 K3[Fe(CN)6] 通过黄酮类脂 (1)。BzNAHCOOK 被证明是跨膜电子传递研究中合适的 NADH 模型,因为 (i) 通过双层膜的渗透性非常低 (k=1.0×10-3 s-1) 和 (ii) 缓慢的水合速率 (k =1.1×10−5 s−1)。用黄酮修饰的人工脂质体从 BzNAHCOOK 到 K3[Fe(CN)6] 的电子通量转换效率比用泛醌 10(一种生物学上重要的电子载体)修饰的脂质体高 6-7 倍。与电子传输有关,
