“…The interaction of glycine with surfaces of inorganic minerals have proved to have a pronounced effect on the formation of metastable polymorphs and complex hierarchical metastructures in the living organisms. [347][348][349][350][351] The problem of the interactions of glycine with gas hydrates was mentioned above in relation to solving a practical problem of preventing blocking in gas pipes. Another aspect of this problem is related to a completely different topic: the origin of life.…”

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.

“…At present, the most well-characterized extraterrestrial organic and mineral materials are found in meteorites [8]; they allow us to investigate the ancient co-occurrence of mineral compounds with organic matter-a cornerstone of some prebiotic experimental work [9]. The magnetic mineral content is particularly significant in the context of molecular evolution [10] [11] as they confer a shielding effect against ionizing cosmic radiation [12]. We propose that studying the mineral and organic content of the Mexican Allende meteorite can provide valuable insights into understanding the molecular evolution of the universe as well as our stellar backyard.…”

The study of the mineral and organic content of the Allende meteorite is important for our understanding of the molecular evolution of the universe as well as the ancient Earth. Previous studies have characterized the magnetic minerals present in ordinary and carbonaceous chondrites, providing information on the evolution of magnetic fields. The interaction of organic compounds with magnetic minerals is a possible source of chemical diversity, which is crucial for molecular evolution. Carbon compounds in meteorites are of great scientific interest for a variety of reasons, such as their relevance to the origins of chirality in living organisms. This study presents the characterization of organic and mineral compounds in the Allende meteorite. The structural and physicochemical characterization of the Allende meteorite was accomplished through light microscopy, powder X-ray diffraction with complementary Rietveld refinement, Raman and infrared spectroscopy, mass spectrometry, scanning electron microscopy, and atomic force microscopy using magnetic signal methods to determine the complex structure and the interaction of organic compounds with magnetic Ni-Fe minerals.
