Abstract
The acid-soluble extract of Tetrahymena geleii W was analyzed by column chromatography. The identification was based on ultraviolet absorption spectra and chromatographic methods, together with chemical and isotopic techniques.
Evidence is given for the presence of 5'-monophosphates of adenosine, guanosine, uridine, and cytidine besides ADP, ATP, UTP, and DPN. In addition, the existence of unidentified phosphate compound which showed sugar reaction was presented.
The natural occurrence of 2'- and 3'-mononucleotides was presented and discussed.
