The alpha helix structure of a protein can be considered an example of:
A) quaternary structure
B) tertiary structure
C) secondary structure
D) primary structure
E) none of the above

Question

Quizplus · Accepted Answer

The alpha helix structure of a protein is a type of secondary structure, which refers to the local folding patterns that occur in specific regions of the polypeptide chain. Secondary structures are stabilized by hydrogen bonding between nearby amino acid residues, such as between the carbonyl group of one amino acid and the amino group of another. The alpha helix is a specific type of secondary structure in which the polypeptide chain is coiled tightly in a right-handed spiral.
