The hysteresis between the equilibrium melting and freezing points ranged from 0.18°C to 0.30°C. The total free amino acid pool almost doubled during winter time. The sum concentrations of 27 free amino acids ranged between 35 – 40 mM in whole body water and 40 – 45 mM in hemolymph during December - February. Two amino acids, Pro and α-Ala most significantly contributed to the seasonal increase, while Gln showed the most dramatic seasonal decrease.
