Hemoproteins, a large class of metalloproteins which have iron protohemeⅨ as a common prosthetic group, play versatile roles in biological systems, such as oxygen transport (e. g. hemoglobin, Hb and myoglobin, Mb), electron transfer (e. g. cytochrome c, Cyt c and cytochrome b_5, Cyt b_5), biological catalysis (e. g. cytochrome P450, Cyt P450 and cytochrome c peroxidase, CcP) and biological sensor (e. g. CooA for CO and sGC for NO). By sharing the same prosthetic group, how various hemoproteins can perform a range of functions by means of different combination of heme and protein scaffolds is a major subject of chemical biology and protein chemistry.
血红素蛋白是一大类含有原卟啉Ⅸ作为辅基的金属蛋白，在生命体系中执行着重要的生物功能，如：血红蛋白(hemoglobin，Hb)和肌红蛋白(myoglobin，Mb)等具有载氧功能，细胞色素c(cytochrome c，Cyt c)和细胞色素b_5(cytochrome b_5，Cyt b_5)等具有电子传递功能，细胞色素P450(cytochrome P450，Cyt P450)和细胞色素c过氧化物酶(cytochrome c peroxidase，CcP)等具有生物催化功能，CO敏感器和NO敏感器(soluble guanylate cyclase，sGC)具有生物传感功能等。
Chemical adsorption self-assembly technology form chemical bond of adsorption between adsorbate and solid surface. Electron transfer, exchange and sharing are happened between adsorbate molecules and solid surface atoms. This kind of technology usually only form single molecular layer.
化学吸附自组装技术，主要是吸附质分子与固体表面的原子、分子等，发生电子转移、交换或公有，从而在吸附质和固体表面之间形成吸附化学键，这种吸附通常只有单分子层。
Last day, Professor Ballinger Lewis introduced you to Lewis who taught us that octet stability could be achieved via electron sharing as an alternative to electron transfer.
昨天，ballinger教授，把我介绍给，他教我们八隅律可以，作为电子传递的方式，可以通过共享电子来实现。
In the development of electron - ic resources, there emerges various forms of library associates of cooperative information resource construc - tion and sharing, and the Shanghai Educational Net Library is one for them.
在电子资源建设过程中，产生了多种形式的信息资源共建共享联盟，上海教育网络图书馆是其中之一。
