CHARACTERIZATION OF THE PHOTOSYNTHETICALLY SYNTHESIZED 'gamma-KETOACID' PHOSPHATE AS A DIPHOSPHATE ESTER OF 2-KETO-L-GULONIC ACID
The summary of this report is that a substance isolated from Chlorella Pyrenoidosa metabolizing {sup 14}CO{sub 2} in the light, previously believed to be a diphosphate ester of a 2-carboxy-4-pentulose, has now been shown to be a disphosphate of 2-keto-L-gulonic acid. The phosphate groups appear to be attached to two of the carbon atoms 3-6. Evidence is presented suggesting that this compound arises from glucose, or a glucose phosphate, which is not in rapid equilibrium with photosynthetically produced glucose derivatives.
