In contrast, after thermolysis of the glycine intercalate under the same conditions the cyclic dipeptide (piperazine-2,5-dione) and unreacted glycine were found. This scheme was applied to an alanine dipeptide and the conformations obtained were observed with all but one of the methods. A preliminary screening of the enthalpy aspect of the problem shows that formation of a dipeptide is endothermic in a neutral process except if the anhydride derivative is used. The resulting molecule is called a "dipeptide", and short stretches of amino acids (usually, fewer than thirty) are called "peptides" or polypeptides.
