Chiral 480nm absorption in the hemoglycin space polymer

Julie E M McGeoch, Malcolm W McGeoch

A 1494 Dalton hemoglycin space polymer of Glycine18 Hydroxy-glycine4 Fe2O4 termed the core unit is part of a polymer of Glycine, Si, Fe and O that forms tubes, vesicles and a latti…

Structural Organization of Space Polymers

Julie E. M. McGeoch, Malcolm W. McGeoch

Extra-terrestrial polymers of glycine with iron have been characterized by mass spectrometry to have a core mass of 1494Da with dominant rod-like variants at m/z 1567 and m/z 1639…

Meteoritic Proteins with Glycine, Iron and Lithium

Malcolm W. McGeoch, Sergei Dikler, Julie E. M. McGeoch

We report that polymer amide [1] with a protein backbone of mainly glycine units and iron is present in the CV3 meteorites Acfer 086, Allende and KABA. The evidence for this is fro…

Hemolithin: a Meteoritic Protein containing Iron and Lithium

Malcolm. W. McGeoch, Sergei Dikler, Julie E. M. McGeoch

This paper characterizes the first protein to be discovered in a meteorite. Amino acid polymers previously observed in Acfer 086 and Allende meteorites [1,2] have been further char…

Polymer amide as a carrier of 15N in Allende and Acfer 086 meteorites

Maclolm W McGeoch, Tomas Samoril, David Zapotok +1

Polymers of amino acids have been found in Allende and Acfer 086, with extra-terrestrial origin evidenced by isotopically enhanced satellite peaks in the 800-1200 Dalton mass range…

A 4641Da polymer of amino acids in Acfer 086 and Allende meteorites

Julie E. M. McGeoch, Malcolm W. McGeoch

A specific 4641Da amino acid polymer entity is present in two CV3 meteorites Acfer 086 and Allende, together with its breakdown polymer fragments of mass < 2000Da. Previously in Al…
