The linear sequence of amino acids within a protein is considered the primary structure of the protein. Proteins are built from a set of only twenty amino acids, each of which has a unique side chain.

This process, known as condensation or dehydration synthesis, results in the formation of a linear chain of amino acids. The sequence of amino acids in a protein, known as its primary structure, ...

Proteins are composed of one or more chains of amino acids, which are linked together by peptide bonds and folded into specific three-dimensional structures. Proteins have four levels of structure: ...

The sequence of amino acids in ... shape of a protein determines its function. This is because proteins form attachments and interact with many other molecules and structures inside organisms.
