Learn about the four levels of protein structure (primary, secondary, tertiary, and quaternary) and how they are determined by amino acid sequence, hydrogen bonds, and non-covalent interactions. Explore the concepts of domains, motifs, and folds in protein structure and the techniques of structural biology.
- Primary Structure. The unique sequence of amino acids in a polypeptide chain is its primary structure. The linear sequence of amino acids in the polypeptide chain are held together by peptide bonds and result in the N-C-C-N-C-C patterned backbone.
- Secondary structure. The local folding of the polypeptide in some regions gives rise to the secondary structure of the protein. The most common shapes created by secondary folding are the α-helix and β-pleated sheet structures.
- Tertiary Structure. The unique three-dimensional structure of a polypeptide is its tertiary structure. This structure is in part due to chemical interactions at work on the polypeptide chain.
- Quaternary Structure. In nature, some proteins are formed from multiple proteins, also known as subunits, and the interaction of these subunits forms the quaternary structure.
Jan 21, 2021 · Learn about the four levels of protein structure (primary, secondary, tertiary, and quaternary) and how they determine the function of proteins. Also, find out the difference between globular and fibrous proteins and what is protein denaturation.

Orders of protein structure: primary, secondary, tertiary, and quaternary. Alpha helix and beta pleated sheet.
- Oftentimes, we are breaking them down to their amino acid bases and creating new proteins. This is because many of the proteins that are found in t...
- The N-terminus refers to the amino end of the amino acid with the nitrogen and hydrogens, and the C-terminus refers to the carboxyl group.
- Your second guess is correct – the two alpha chains are identical (as are the two beta chains). This nomenclature is confusing and the designation...
- This is a great question, but actually quite complicated so I'm not going to try to give a complete answer — I have given some useful links below i...
- The function of tertiary and quaternary structure varies depending on type of protein, but in enzymes, the specific shape and configuration of the...
- The secondary structure is formed by hydrogen bonds between carbonyl and amino groups that make up the *polypeptide backbone* and causes the molecu...
- Proteins can fold into various structures/sizes (secondary, tertiary, quanternary) for various biological tasks. Think of it literally as proteins...
- Sickle cell anaemia is caused by a single point mutation of the gene coding for haemoglobin. As a result, a hydrophobic amino acid (valine) replace...
- In biochemistry, denaturation is a process in which proteins or nucleic acids lose the quaternary structure, tertiary structure, and secondary stru...
