ABSTRACT:
A slow but steady decline in glycogen content of the digestive gland, an initial decline followed by some increase in the glycogen content of the food muscle and little or no change in the glycogen content of heart muscle were observed in Achatina achatina following prolonged starvation and aestivation.2.2. The free fatty acid (FFA) content of the digestive gland and heart muscle increased rapidly initially, then declined slightly and finally started increasing as starvation was prolonged, whereas the FFA content of the foot muscle increased slightly initially and declined only slowly subsequently as starvation/aestivation was prolonged.3.3. There was no difference in the activities of fructose diphosphatase and phosphoglucomutase in the foot muscle of fed and starved snails but glucose-6-phosphatase activity was consistently 30–47% lower in the foot muscle of starved snails than in those of fed snails.4.4. Succinate, lactate and alanine appeared to be produced in the ratio of 2:1:3 in the foot muscle of snails starved for 21 days.5.5. Malate dehydrogenase, malic enzyme and citrate synthase were localized in both the mitochondrial and cytosol fractions obtained from food muscles of starved snails; pyruvate kinase, lactate dehydrogenase, phosphoenolpyruvate carboxykinase and citrate lyase were localized in the cytosol fraction; whereas glutamate dehydrogenase and fumarate reductase activities were predominantly mitochondrial in distribution.
