Polyamino acids: preparation from reported proportions of "prebiotic" and extraterrestrial amino acids.

Polyamino acids were thermally prepared from the proportions of amino acids identified (sometimes after hydrolysis) among the products of simulated prebiotic syntheses and (after hydrolysis) in lunar and meteoritic samples. Inferences are made concerning the composition of prebiotic protein and the possible extraterrestrial existence of protein-like polymers.
