The Alpha Helix: A Fundamental Protein Structure

The alpha helix is a ubiquitous secondary structure element found in proteins. It is characterized by a specific arrangement of the polypeptide backbone, where each amino acid residue is stabilized by a hydrogen bond between the carbonyl oxygen of one residue and the amide hydrogen of the amino acid four residues further along the chain. This arrangement results in a right-handed helical conformation with approximately 3作者：SK Zhang·2016·被引用次数：223—AR-23 is a melittin-related peptide with 23 residues.
