Peptide formation under high P and T conditions: new carbon fibers

Peptides are formed through the enzymatic actions in living organisms, but difficulty exists to form peptide by non-enzymatic actions. Here we report the success of peptide formation under anhydrous, high P and T conditions. We were successful to form 11-mer of glycine and 5-mer of alanine. They are important constituents of spider silk, which is a candidate of next generation of carbon fibers. Therefore, our techniques have potentials to apply making new carbon fibers without biotechnology.
