This is expected and similar to other meteorites. It's nice to confirm it and probably an specialist can pick an importatn detail that I'm missing. From the research article: > The higher relative abundance of glycine and other alpha-amino acids compared to beta–, gamma–, and delta–amino acid isomers suggests a formation by HCN polymerization and/or Strecker-cyanohydrin synthesis (29) inside Hillsborough’s parent body during an early aqueous alteration phase at moderate temperatures. That is above my level of chemistry, but at least I can try to translate it. It's common for HCN to react slowly outside cells and produce molecules that have a few HCN glued together, and they produce the amino acids made by living things on Earth and also other amino acids. This is standard chemistry, but as I said above my level. Some info in Known organic molecules in deep space: https://en.wikipedia.org/wiki/List_of_interstellar_and_circu... Titan has lakes of hidrocarbons and a organic brown goo that was produced by non-life chemical reactions https://en.wikipedia.org/wiki/Titan_(moon) |
