Resumo1. When 14C-labeled tryptophan-3 was injected into boll weevils, Anthonomus grandis Boheman, the amount of radioactivity in the free amino acids pool dropped quickly at first and then more gradually until the twelfth hr post injection. Incorporation into the lipoprotein and protein fractions also peaked at 12 hr but with the nucleic acids, incorporation was gradual. 2. All RNA bases were labeled early (4 hr) but complete labeling of the DNA bases did not occur until 18 hr postinjection. The amount of labeling varied with time. 3. The lipid fraction was labeled, but activity was too low to determine the extent of incorporation into individual fatty acids. 4. Both essential and non-essential amino acids were labeled.
