The primary structure of a protein is its amino acid sequence.
Amino acids are covalently bonded together into polypeptide chains by peptide linkages.
The secondary structure of a protein requires hydrogen bonding.
There are two basic types of secondary structure:
The
The tertiary structure of a protein is formed by folding and bending.
The strongest links holding a folded polypeptide in place are from the bonds between neighbouring cytesine amino acids, which form disulfide bridges.
Other interactions folding the polypeptide include ionic bonds - which can form between positively and negatively charged side chains, hydrogen bonds and hydrophobic interactions.

These are just another name for dispersion forces. I'm sure you're familiar with these from Chemistry.
