Abstract Catalytic properties of aluminosilicates may play a role in the synthesis of biological molecules from simple gaseous molecules commonly found in planetary atmospheres. Urea, amino acids and UV absorbing substances have been obtained by heating CO and $ NH_{3} $ with Linde molecular sieves saturated with $ Ca^{+2} $, $ NH_{4} $+ or $ Fe^{+3} $. The yields of amino acids produced have been determined by an amino acid analyzer. The quantity of urea produced largely depends on the nature of the saturating cation. Experiments $ using^{14} $CO confirm that the amino acids are not due to contaminants adsorbed on the surface of the molecular sieves.
