What are the similarities and differences of intermolecular interactions that stabilize secondary versus tertiary structure? Think about types of interactions, side-chain versus backbone interactions, and proximity of the residues involved. The molecule considered is a protein: pancreatic amylase.

As per the central dogma of molecular biology, DNA contains the code that is necessary for the synthesis of protein. The code from DNA is transcribed onto an mRNA and then ribosomes translate the code on mRNA into a polymer of amino acids called a polypeptide. The polypeptide then 'folds' into a functional three-dimensional structure that is called proteins. A protein's function depends on its three-dimensional structure. The 3D structure is formed due to protein folding. The amino acid sequence of the protein determines the 3D structure that the protein would fold into.
Proteins are large high molecular weight molecules and have diverse functional roles to play in a cell. One such role is the catalysis of biochemical reactions. Protein molecules that catalyse the biochemical reaction are called enzymes.
Pancreatic amylase is an enzyme that hydrolyses starch into glucose and maltose.
