Question

$\alpha$-helix structure refers to:

• A. Primary structure of protein
• B. Secondary structure of protein
• C. Tertiary structure of protein
• D. Quaternary structure of protein

Hint:

The $\alpha$-helix is a secondary structure, one of the most common types of protein folding.

Answer 1

The Correct Option is B

The $\alpha$-helix structure is a type of secondary structure found in proteins. It is a coiled shape stabilized by hydrogen bonds between the backbone atoms in the polypeptide chain. The primary structure refers to the amino acid sequence, while the tertiary structure relates to the overall 3D shape of a single protein molecule, and the quaternary structure involves the interaction between multiple protein chains.
