- cytosine (n.)
[cytosine 词源字典]
- 1894, from German cytosin (1894), from cyto- "cell" + -ose + chemical suffix -ine (2). "The name cytosine (due to Kossel and Neumann) is misleading. Cytosine is not, like adenosine and guanosine, a nucleoside but the sugar-free base." [Flood][cytosine etymology, cytosine origin, 英语词源]
