Outlook Toward Origin of Organic Compounds in Space

Outlook Toward Origin of Organic Compounds in Space 

Prebiotic organics are a prerequisite to the origin of life, and shock waves must have actively participated in the formation of the prebiotic organics. On the other hand, a wide variety of organic species occurs on the present Earth, and they are genetically related more or less with biological activities. However, some organics such as hydrocarbons in the Earth s mantle [171] and amino acids
