Question

explain alpha-helical structure of protein​

Answer 1

Explanation:

An alpha helix is a common shape that amino acid chains will form. The alpha helix is characterized by a tight right-handed twist in the amino acid chain that causes it to form a rod shape. Hydrogen bonds between the hydrogen in an amino group and the oxygen in a carboxyl group on the amino acid cause this structure

Answer 2

Answer:

The telephone cord shape of the alpha helix is held in place by hydrogen bonds between every NH group and the oxygen of a C=O group in the next turn of the helix, four amino acid down the chain. The typical alpha helix is about 11 amino acid long.
