LEVELS OF PROTEIN STRUCTURE 1. Sequence of amino acids represents the primary structure of a polypeptide. [As we have said, a critical feature of a protein is its ability to fold into a 3- Dimensional conformation. Each protein exists in a unique conformation (or sometimes in a series of alternate conformations. The conformation is described in terms of several levels of structure.] 2. Secondary structure is generated by the folding of the primary sequence. This is possible because of the ability to move about bonds of free rotation. Secondary

Unformatted text preview: structure refers to the path that the polypeptide backbone of the protein follows in space. Protein structures are extremely versatile but certain types of secondary structure are relatively common. They result from hydrogen bonding between the NH and CO groups of the polypeptide backbone. The two most common types of secondary structure observed are the alpha helix & beta-sheet...
