Asymmetric Distribution of C14 in the Glucose Phosphates Formed During Photosynthesis.

Abstract
Photosynthesis was carried out with Chlorella using labelled Cl4o2: (1) after illumination for 5 min. in atmosphere of N2 and for 10 sec. after introduction of C14O2 and (2) incubation of cells with C14O2 in the dark for 5 min. and then 1 min. of light. The glucose was isolated from the sugar phosphates, and the labelling in the carbon atoms followed. The labelling pattern is not that which is expected if two equal triosephosphates combined to yield a hexosephosphate.
