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.

Proteins have four levels of structure: primary (amino acid sequence), secondary (local folding patterns like alpha helices and beta sheets), tertiary (overall 3D shape), and quaternary (assembly of ...

The central dogma of molecular biology suggests that the primary ... in DNA into proteins. In reality, there is much more to the RNA story. However, in the half-century since the structure of ...

Protein is an essential macronutrient that forms the building blocks of every cell in your body. When you consume animal or plant-based protein, your body breaks it down into amino acids. Your cells ...

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, ...

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 ...
