Structural organization of space polymers

Extraterrestrial polymers of glycine with iron have been characterized by mass spectrometry to a core 1494 Da dominant rod-like variants at charge ratios 1567 and 1639 [McGeoch et al., “Meteoritic proteins glycine, lithium,” arXiv:2102.10700 (2021)]. Several principal macro-structural morphologies are observed in solvent extracts from chondritic Vigarano class alteration type 3 meteoritic material. The first is an extended sheet linked (three-legged) triskelia containing the entity that encloses gas bubbles solvent. A second fiber-like crystals found here, via x-ray diffraction, be multiple-walled nanotubes made square lattice polymer. third dispersion floating phantom-like short tubes up 100 μm length characteristic angled bends suggest influence specific underlying protein structure. Here, it proposed observable result space-filling superpolymerization 1638 polymer subunits guided tetragonal symmetry linking silicon bonds. Distorted hexagonal sheets perpendicular three-dimensional diamond structure fill largest possible volume. This very low-density conjectured dominated process chemical selection because captured maximum amount molecular raw material ultra-low density clouds or proto-solar nebula. could led ultimately accretion earliest planetary bodies.
