Solution: List and define the four levels of structure in a functional protein.
List and define the four levels of structure in a functional protein.
The four levels of structure of proteins are the following:
Primary: this structure is simply the amino acid sequence in a polypeptide chain.
Secondary: refers to local folded structures that form within a polypeptide due to interactions between atoms of the polypeptide chain backbone (aside from the r group atoms). The most common types of secondary structures are the α helix and the β pleated sheet.
