Synthesis and Metabolism of Carbonyl-C14 Pyruvic andHydroxypyruvic Acids in Algae
1. Pyruvic and hydroxypyruvic acids a r e metabolized by Scenedesmus. 2. The products of metabolism of pyruvic -2 -C{sup 14} and hydroxypyruvic-2 -C{sup 14} acids a r e essentially identical to those of C{sup 14}-O fixations. 3. Lipids a r e rapidly formed i n the light from both substrates. In the dark the major products a r e intermediates of the tricarboxylic acid cycle. 4. Zt does not appear likely that f r e e hydroxypyruvic acid is a photosynthetic intermediate, 5 . Tricarboxylic acid cycle intermediates a r e formed from exogenous pyruvate a s fast in the light a s in the dark.
