  1. Protein structure: Primary, secondary, tertiary & quatrenary (article ...

    To understand how a protein gets its final shape or conformation, we need to understand the four levels of protein structure: primary, secondary, tertiary, and quaternary.

  2. Four levels of protein structure (video) | Khan Academy

    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 understand how …

  3. Overview of protein structure (video) | Khan Academy

    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, that's …
