Description

Abstract 1. 1. The amount of the principal inorganic ions in the hemolymph of Achatina fulica Ferussac was 5831 ± 57 μ/ml when feeding and 6486 ± 81 μg/ml in starvation. 2. 2. The amount of measured free amino acids in the hemolymph was 0·485 ±0·141 μmoles/ml when feeding and 0·457 ± 0·123 μmoles/ml in starvation. 3. 3. The amount of measured free amino acids in whole subesophageal ganglia (with connective tissue) was 38·3 ± 6·3 μmoles/g when feeding and 30·6 ± 6·7 μmoles/g in starvation. 4. 4. Threonine-serine, alanine and glycine were dominant in the hemolymph and threonine-serine, alanine, lysine and glutamic acid were dominant in the subesophageal ganglia.
