alfaheliksin

Alfaheliksin is a type of protein secondary structure. It is characterized by a specific arrangement of amino acid residues that form a coiled helical shape. This structure is stabilized by hydrogen bonds between the carbonyl oxygen of one amino acid residue and the amide hydrogen of another residue located four positions further along the polypeptide chain. The side chains of the amino acids extend outward from the helix axis. Alfaheliksin is one of the most common secondary structure elements found in proteins, playing a crucial role in protein folding and the overall three-dimensional structure of proteins. The precise geometry and stability of an alfaheliksin depend on the amino acid sequence and the surrounding environment.
