The shape of proteins primarily is determined by the order of amino acids (the building blocks of proteins, all strung together in a single line, can be ten's of thousands long). Interactions between the building blocks causes the proteins to fold and twist on itself (1) and multiple protein molecules can come together to shape bigger molecule complexes (2).
Proteins are built as chains of amino acids, which then fold into unique three-dimensional shapes. Bonding within protein molecules helps stabilize their structure, and the final folded forms of proteins are well-adapted for their functions.

Round
If a proteins shape is changed it has likely been denatured. This is often a breakdown and rearrangement of the protein.

It has to keep its shape to do its particular job.
carrier proteins transport glucose into a muscle cell
Tritiory proteins are globular proteins. Every enzyme is a globular proteins.
There are no side chains in proteins, but the side chains in amino acids, the building blocks of proteins, determine their unique properties.
