ResumoThe incorporation of 14C from labelled glucose into non-essential free amino acids was highest at puparium formation. The labelled amino acids declined substantially during pupal development with minor changes appearing in the pharate adult. The total amount of unlabelled free and peptide amino acids tended to exhibit a U-shaped curve during metamorphosis. Changes in the essential free amino acids correlate well with periods of tissue histolysis and protein synthesis. The non-essential free amino acids exhibit changes which indicate that these amino acids may be utilized as an energy source during early metamorphosis and contribute to protein synthesis in the pharate adult.
