The structural elements that are important in the formation of the threedimensional
structure of a protein, i.e. the secondary structure of a protein,
are segments of consecutive amino acids forming regular structural patterns
called -helices and -strands. An α-helix is a winding spiral that stabilizes by
forming hydrogen bonds between neighboring turns, and a β-strand is a straight
segment of the amino acids sequence that stabilizes by forming hydrogen bonds
between neighboring -strands that run in parallel ...
