A model of a protein shows a spiral secondary structure known as an alpha helix. How many amino acids are typically found in each turn of this helix?
Q1. A model of a protein shows a spiral secondary structure known as an alpha helix. How many amino acids are typically found in each turn of this helix?
Answer: 3.6 amino acids
Explanation: Alpha helix is a common secondary structure with 3.6 amino acids per turn, stabilized by hydrogen bonds, not covalent disulfide bridges.
