论文摘要
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 lattice structure isolated from CV3 meteorites and characterized by mass spectrometry, FIB/SIMS and X-ray analysis.在Hartree-fock计算中，聚合物在480nm处具有蓝光的吸收，这取决于羟基 - 甘氨酸残基的直肠R（=右旋）手性，其C末端与铁原子键合成。该吸收起源于手性对称性破裂的结果。提出了红外光谱。我们讨论如何通过早日蓝光在我们的原行星光盘中选择45亿年的核心单位。
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 lattice structure isolated from CV3 meteorites and characterized by mass spectrometry, FIB/SIMS and X-ray analysis. In Hartree-Fock calculations the polymer has an absorption of blue light at 480nm that is dependent on rectus R (= dextro D) chirality in a hydroxy-glycine residue whose C-terminus is bonded to an iron atom. The absorption originates in the Fe II state as a consequence of chiral symmetry breaking. The infrared spectrum is presented. We discuss how the core unit could have been selected 4.5 billion years ago in our protoplanetary disc by blue light from the early sun.
