We report that polymer amide [1] with a protein backbone of mainly glycineunits and iron is present in the CV3 meteorites Acfer 086, Allende and KABA.The evidence for this is from particles of these meteorites after Folchextraction being analyzed by MALDI mass spectrometry and from the 3D physicalstructures that form in the various Folch solvent phases. The two physicalforms we observe are branching rods and entrapping spheres on the 100micronscale. Two potential molecular structures of polymer amide are presented inthis report. One we term hemolithin of mass 2320Da, contains glycine,hydroxy-glycine, Fe, O and Li. The other, we term hemoglycin of mass 1494Da isof glycine, hydroxy-glycine, Fe and O. Hemoglycin is connected covalently intriplets by silicon to form a triskelion. Analysis of the complete spectrum ofisotopes associated with each molecular fragment shows very high 2H enhancementabove terrestrial averaging 25,700 parts per thousand (sigma = 3,500, n=15),confirming extra-terrestrial origin and hence the existence of these moleculeswithin the asteroid parent body of the CV3 meteorite class. The hemoglycintriskelia join via silicon bonds into an extended lattice, as seen in massspectrometry of lattice fragments at m/z 4641 and above [2]. The identificationof hemolithin and hemoglycin required careful methodology at room temperaturewith the minimum of steps up to mass spectrometry analysis ensuring that onlythe laser step fragmented the molecules. The 3D structures were imaged throughpermanently closed Folch extraction V-vials at a magnification of 10.
