You don't break a hymen.    The hymen is tissue surrounding the vaginal opening, it is flexible  so can stretch to allow penetration without tearing-the hymen can  tear if it is wide, delicate, or if penetration is either rough or  forced, but it does not 'break'.
A peptide bond can be broken by hydrolysis (the adding of water). In the presence of water they will break down and release 8â16 kilojoule / mol (2â4 kcal / mol) of free energy. This process is extremely slow.In living organisms, the process is catalyzed by enzymes. peptide bond can be broken by hydrolysis (the adding of water).
