title: Structural characterization of thermal prebiotic polypeptides.
abstract: Thermal polycondensation of amino-acids as a possible prebiotic path of chemical evolution of life has been critically examined. The polymeric materials studied by nmr methods have scarce resemblance to natural peptidic material because beta, gamma and eplision peptide bonds largely predominate over a-peptide bonds.
