A beta sheet is an example of protein secondary stucture. Another common folding pattern is known as an alpha-helix. 

Beta sheets occur due to hydrogen bonds between the amine and carboxyl groups of the polypeptide backbone, thus making it a very strong and rigid structure. because the hydrogen bonds occur between the groups on the backbone and not the side chains on the amino acids, many different sequences of amino acids (therefore many different proteins) can fold to produce beta sheets.

There are two types of beta sheets, parallel and anti-parallel sheets. Parallel beta sheets are chains of polypeptides which run in the same direction. Anti-parallel beta sheets are chains of polypeptides which run in opposite directions to each other [1].
