Metabolism of C14-Glucose by Moniliformis dubius (Acanthocephala)

Mature male worms from fasted animals absorbed more glucose-U-C14 and incorporated more radioactivity into glycogen than did female worms. The rate of glycogenolysis was slower in males than in females, based on the rate of disappearance of radioactivity in glycogen, when worms, after short incubations in the isotope, were reincubated in buffer without glucose. Moniliformis incorporated glucose-U-C14 carbon into alanine, aspartic acid, serine, and malic, lactic, succinic, and fumaric acids, but not into citric, aconitic, glutamic acids, or glycine. Other radioactive compounds presumed to be glycolytic intermediates were also found.
