MCQ on Alpha Helix Structure of Protein




The alpha helix is a common secondary structure in proteins, where a polypeptide chain forms a helical structure stabilized by hydrogen bonds between its amino acid residues. This compact, coiled shape contributes to the protein’s overall three-dimensional structure and functionality. This is an MCQ on Alpha Helix of Proteins.
