The rates of acid-catalyzed hydrolysis of a hypermodified nucleoside, wyosine and its 5'-monophosphate were determined at various pH, temperature and buffer concentrations. The results show that despite distinct differences in structure and the glycosyl bond stability, the hydrolysis of wyosine proceeds via cleavage of the C-N bond by A-1 mechanism,(More)
Nowadays it is well known among historians of science that Francis Bacon, one of the modern defender of the experimental method, owed much of his thoughts to the chemical or alchemical tradition (cf. e.g., Gregory 1938, West 1961, Linden 1974, and Rees 1977).
