Hemoglycin as a Candidate for Permanent Memory
Julie E. M. McGeoch, Malcolm W. McGeoch
The Hemoglycin polymer of glycine derived from space is terminated by iron and silicon to form a three-dimensional regular lattice with a high density of silicon tetrahedral vertic…
Space-filling efficiency and optical properties of hemoglycin
Julie E M McGeoch, Malcolm W McGeoch
The empty, extensive low-density lattice topology of hemoglycin is examined to understand how in space, and possibly as early as 800M years into cosmic time a rod-like polymer of g…
Sea Foam contains Hemoglycin from Cosmic Dust
Julie E. M. McGeoch, Malcolm W. McGeoch
In-falling cosmic dust has left evidence of meteoritic polymer amide in stromatolites, both fossil and modern. In search of evidence for continued present day in-fall sea foam was…
Polymer amide as a source of the cosmic 6.2 micron emission and absorption
Julie E. M. McGeoch, Malcolm W. McGeoch
Cosmic infrared emission and absorption spectra often carry a well-defined and invariant 6.2 micron band that has been proposed to emanate from very small dust grains that may carr…
Fossil and present-day stromatolite ooids contain a meteoritic polymer of glycine and iron
Julie E M McGeoch, Anton J Frommelt, Robin L Owen +4
Hemoglycin, a space polymer of glycine and iron, has been identified in the carbonaceous chondritic meteorites Allende, Acfer 086, Kaba, Sutters Mill and Orgueil. Its core form has…
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…
