The next level of protein structure, secondary structure, refers to local folded structures that form within a polypeptide due to interactions between atoms of the backbone.

Secondary structure: A protein’s secondary structure involves folding of the amino acid chain into repeating structures such as alpha helices and beta sheets. These structures are primarily …

Now, any protein that's made up of a single polypeptide is only going to have primary structure, secondary structure and tertiary structure, but if we're dealing with something like hemoglobin, …

The four levels of protein structure are primary, secondary, tertiary, and quaternary. It is helpful to understand the nature and function of each level of protein structure in order to fully …

A new drug is developed which selectively cleaves covalent bonds between two sulfur atoms of non-adjacent amino acids in a polypeptide chain. Which level of protein structure in affected …

And then next, you have secondary structure, which just refers to the local substructures in a protein. And they are determined by backbone interactions held together by hydrogen bonds.

The disulfide bond is the oxidized form of the molecule, and the reduced form is the two cysteines with -SH. Disulfide bridges can exist both inside and outside of cells-- they are an example of …

The secondary structure of a native conformation refers to the three dimensional organization of the main chain atoms of a protein. The main chain atoms of a protein are the atoms that all …

This article goes over the forces driving protein folding and the forces that stabilize protein structure, as well as causes of protein denaturation.

Primary structure is just a sequence of the amino acids. But then from there we can start thinking about how does it get shaped by thinking about the secondary structure.
