A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O).
The peptide bonds in proteins are metastable, meaning that in the presence of water they will break spontaneously, releasing about 10 kJ/mol of free energy, but this process is extremely slow.
If the amino acid sequence of a polypeptide is known then computer programs can caluclate the possible angles, and predict the likely folding of the polypeptide in alpha-helix, beta-sheet, etc.
