Explanation:
Protein Structure: Proteins are one of the most important biomolecules in living organisms. Proteins are made up of long chains of amino acids which are linked together by peptide bonds. A protein's structure can be described at four different levels: primary, secondary, tertiary, and quaternary structure.
Helical Structure: The secondary structure of a protein refers to the way in which the amino acid chain is folded or coiled. One of the most common secondary structures is the alpha-helix. The alpha-helix is a coiled structure that resembles a spring. It is held together by hydrogen bonds between the amino acids in the chain. The alpha-helix is a common structural motif in many proteins.
Other Secondary Structures: Other common secondary structures include the beta-sheet and the beta-turn. The beta-sheet is a flat structure that is held together by hydrogen bonds between amino acids in different parts of the chain. The beta-turn is a structure that allows the protein chain to reverse direction.
Function of Secondary Structure: Secondary structure plays an important role in protein function. It helps to stabilize the protein structure and allows it to fold into its correct shape. This is important for the protein to carry out its specific function in the cell.
Conclusion: Therefore, the helical structure refers to the secondary structure of a protein.
