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 mater...
