Isolation of a Hexosemonophosphate From Pea Leaves

THE INFLUENCE OF LIGHT, TEMPERATURE, AND SOME ENZYME POISONS UPON THE TOTAL ORGANIC ACID CONTENT OF LEAF TISSUE OF KALANCHOE DAIGREMONTIANA (HAMET AND PERRIER)

“…One of these might be phosphoric acid and its esters, particularly the hexosephosphates. There is considerable evidence that these esters are present in plant tissues (4,15,21,40,41). In view of the recent work with phosphorylation in plant tissue extracts and intact plant organs (see STAUFFER, 39) it appears probable that during changes in carbohydrate content there may be changes in the relative amounts of various phosphate esters and their salts.…”

Relationships Between Phosphorylation and Photosynthesis in Chlorella

“…Albaum and Umbreit (1943) identified. Hexose phosphates have been isolated by Burkard and N euberg (1934) and by Hassid (1938). Hexosediphosphate is readily used by some plants (Andersson, 1932), and the phosphorylase system (starch glucose-I-phosphate) is present in at least a few plants (Hanes, 1940a, b).…”

Relationships Between Phosphorylation and Photosynthesis in Chlorella

“…Furthermore, James and co-workers (1939, 1940, 1941a, 1941b) have provided evidence that certain other steps in the phosphorylative scheme applicable to muscle or yeast also exist in plants. Hexose phosphates have been isolated by Burkard and N euberg (1934) and by Hassid (1938). However, the presence of phosphorylative reactions in Chlorella has not been determined.…”
