Scientific paper

Amino acids are critical building blocks for proteins. The most important ancient source for them could have been the ammonia ice which was a basic ice component in the models of the early Solar System. Outer Solar System bodies may have preserved ammonia and some of its compounds in ice form, or in the form of ammonia(um)-silicates. Ammonia could be the solvent for life molecules, too. The sources of the other, more important component and solvent for life molecules, water, are better known. We estimated simultaneous occurrence of ammonia and water: in atmospheres of Jupiter, Saturn, and Titan. For comparisons terrestrial planet possibilities are also shown. Additional information is contained in the original extended abstract.
