Asymmetry is often designated as right- and left-handed. The right- and left-handed helical hypergravity (HG) field can be artificially produced. In this paper, it is shown that the α-amylase activity is dependent on both the magnitude and direction of HG within the range between 1 g and 9 000 g. The right-handed HG has larger enhanced effect on enzyme activity than the left-handed HG. Considering the circadian rhythm of natural gravity on the earth, it is suggested that circadian rhythm of natural gravity may be an important mechanical factor for the origin of biological circadian rhythms.
