Notes:
Fifteen alcohol-soluble carbohydrates have been isolated from logphase cultures of Tetrahymena. Preliminary results obtained by parallel chromatography of impure extracts indicate that some of the soluble components were 2-D-deoxyribose, ribose, mannose, fructose, arabinose, xylose, and glucose. Another elution gradient with extracts from cells washed several times, indicates that maltose and glucose were the only identifiable components as compared with 18 known standards. Differences were observed in the alcohol-soluble carbohydrate content in log-phase versus stationary-phase cells. For example, it is clearly indicated that component 13 is missing in stationary-phase cells while component 15 is missing in log-phase cells. Fifteen alcohol-soluble carbohydrates have been chromatographed from synchronized cells. All of these compounds show cyclic variation in relation to cell division. Component 13 accumulates in cells blocked in morphogenesis and decreases as oral development proceeds in synchronized cells.
