title: [Seasonal variations of free amino acids the content of body flows in the fresh-water mollusk Lymnaea stagnalis].
abstract: Institute of Cell Biophysics, Russian Academy of Sciences, Pushchino, Moscow region, 142290 RussiaIt has been shown that in the autumn at 0 degrees C, the concentrations of free alanine and histidine of body flows in the freshwater mollusk L. stagnalis was about 3 times as great as in the summer. Lysine were absent in the summer but were registered in autumn at + 4 degrees C, and their concentration increased at 0 degrees C to reach 20.5+/-1.2 mkmole/100 ml. On the stage of deep hypobiosis, the concentration of free all amino acids abruptly decreased.
