Proteins form in different shapes and structures. Some proteins are globular (spherical), compact and water-soluble, while other proteins are fibrous and elongated, physically tough, and water-insoluble. Chemical bonds are responsible for the shapes that proteins maintain.
Protein structure is determined by amino acid sequences. Learn about the four types of protein structures: primary, secondary, tertiary, and quaternary.
There are four levels of protein structure; the primary structure, the secondary structure, the tertiary structure, and the quaternary structure. Furthermore, there are two main classes of 3D protein structures; these are globular and fibrous proteins.
The primary structure of a protein refers to the sequence of amino acids in the polypeptide chain. The primary structure is held together by peptide bonds that are made during the process of protein biosynthesis.
Protein Folding and Structure. To understand how the protein gets its final shape or conformation, we need to understand the four levels of protein structure: primary, secondary, tertiary, and quaternary. For a short (4 minutes) introduction video on protein structure click here.
Protein Structure - There are four levels of protein structure namely Primary protein structure, Secondary protein structure, Tertiary protein structure, and Quaternary protein structure.

Proteins are polypeptide structures consisting of 1 or more long chains of amino acid residues. They perform various organism functions, including DNA replication, transporting molecules, catalyzing metabolic reactions, and providing cell structural support.
The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique...
The Structure section contains information about the predicted three-dimensional structure of 19904 human proteins and their related isoforms. Interactive 3D protein structures based on predictions generated using the AlphaFold source code are shown with the possibility to highlight selected regions and positions in the structure.
