A possible scenario to form pre-biotic molecules in space

Summary. A good many number of pre-biotic molecules have been discovered in the star forming regions. Amino acids have also been detected in meteorites that are believed to be formed in the proto-solar system. These imply that the frigid interstellar medium could be the cradle of the formation of bio-molecules, if not of life itself. We present our preliminary results of numerical simulations of the evolution of various chemical species during the star formation. We show that some amount of simple amino acids such as glycine and alanine and DNA bases like adenine may also be formed in the process.
