摘要: The evolution of icy grain mantles is governed by the environment in which they exist. This review presents an overview study molecules that make up and discusses their relevance to origin life. Models predict two phases mantle growth during cloud collapse: simple polar nonpolar dominate layers at early late times, respectively (Section 1). effect processing on composition connection between organics prebiotic chemistry introduced. Section 2 describes how infrared spectroscopy dense sources, combined with theoretical models laboratory data, gives us information abundance ices varying regions. observed features are used as diagnostics discussed 3. section also importance these chemistry. 4 compares different low-mass star forming regions, best represent solar birthplace. final 5) summarizes presented, emphasizing link interstellar dust
