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.

The sequence of amino acids in a protein, known as its primary structure, determines its unique three-dimensional shape and function. Proteins can further fold and assemble into complex structures, ...

Astro Brief is a collaboration between KSMU, the Missouri Space Grant, and MSU's Department of Physics, Astronomy and Materials Science. Hosted by Dr. Mike Reed, Astro Brief focuses on astronomical ...

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 the chain determines how the chain will fold up to make the protein, so different proteins have different three-dimensional shapes. The three-dimensional shape of a ...
