Amino acids are among the earliest organic molecules to exist on Earth, and the origin of such bio-molecules on Earth is still a topic of intense discussion in the associated scientific area. In this regard, one of the crucial methods to investigate this subject and to better comprehend the emergence of biomolecules on the planet is to carry out indoor laboratory-size shock wave recovery experiments. In this instance, we have investigated the structural and morphological properties of l -serine powder samples processed using acoustic shock waves. The effects of shock waves on the title sample have been studied using conventional diffraction and microscopy methods. According to the diffraction results, under shocked conditions, there has been no crystallographic phase change observed, whereas the entire test samples have undergone dynamic recrystallization with the same P 2 1 2 1 2 1 space group. Shock wave-driven dynamic recrystallization theories can explain the observed surface changes on the test samples, which underwent considerable surface modifications under shocked conditions.
