However, most of the organic nanoglobules from extraterrestrial materials have isotopic anomalies in the form of deuterium and 15 N enrichments (Nakamura-Messenger et al. [2006]; De Gregorio et al. [2010]), which represents a significant difference from our category 3 particles because they do not display isotopic anomalies (Ito et al. [2014]).
