Final answer:
A small generic section of the primary structure of an α helix refers to a helical arrangement of amino acids with hydrogen bonds stabilizing the structure. It is a common secondary protein structure found in proteins.
Step-by-step explanation:
The small generic section of the primary structure of an α helix refers to a segment of amino acids that are arranged in a helical shape with hydrogen bonds stabilizing the structure. The α helix is a type of secondary protein structure found in proteins.
To form an α helix, every fourth amino acid in the sequence forms a hydrogen bond with the amino acid four positions ahead, creating a twisting shape. This helical structure is important for the overall organization of proteins and can impact their function.
For example, in proteins like keratin, α helices provide strength and flexibility to the structure. In myoglobin, an α helix is involved in binding and transporting oxygen. Overall, the α helix is a common structural motif in proteins, contributing to their stability and functionality.
