title: [Effects of starvation on incorporation of glycine in organs of Philosamia cynthia walkeri].
abstract: The influence of starvation on protein synthesis in organs from growing Philosamia larvae has been determined. In the fat body, a rapid and continuous decrease in synthesis begins at the onset of starvation. A decrease also occurs in the carcass, but of lesser extent. In the intestine and silkgland, the synthesis increases significantly during the first 12 hours and decreases thereafter. In all organs, the acid soluble glycine pools are drastically modified by starvation for 48 hours: this amino-acid accumulates in the silkglands, remains at a rather stable level in the intestine but decreases in the fat body and carcass. No adjustement of these pools is found at the level of haemolymph acid soluble glycine which increases during the 48 hours. These results are discussed in the context of regulatory mechanisms on metabolic level during feeding or food deprivation periods.
