“…[8,9] It was supposed that these different crystal shapes correspond to different crystal structures, i. e. glycine can form polymorphs. After the crystal structures of all the three polymorphs were solved, the polymorphs were named α-, [10][11][12][13] β-, [14,15] γ- [16,17] (Figure 1). Later these structures were rerefined many times to obtain detailed information on the electron charge density and precise intra-and intermolecular distances with particular emphasis on the geometry of hydrogen bonds, atomic displacements and other fine features of the structures.…”

Glycine is a small molecule. It cannot change its conformation and is achiral. Despite the apparent simplicity, glycine shows endless diversity in its behavior over many phenomena. It was the first amino acid for which polymorphism was reported, first on crystallization and then on hydrostatic compression. The polymorphs differ in their physical properties and their biological activity. Glycine clusters persist in solution, leading to "solution memory". Phenomena at interfaces are critically important for crystal growth, dissolution, and for physical properties, which can be at times unexpected, like polarity in centrosymmetric αpolymorph. It is a great pleasure to remind of these remarkable phenomena in a special issue honoring professors Meir Lahav and Leslie Leiserowitz, who pioneered the study of the behavior of this unique molecule in many respects, and showed how complex and non-trivial phenomena can be at interfaces: between phases and between research fields.

“…The first data on the space group and cell parameters of a-glycine were published in 1931 [23]; then, and again in 1936 [26,27], attempts were made to deduce the atomic structure of a-glycine. A complete structure study was performed in 1939 [24,28];…”
