Beta Sheet Secondary Structure - This structure occurs when two (or more, e.g. Web the secondary structure is formed by hydrogen bonds between carbonyl and amino groups that make up the polypeptide backbone and causes the molecule to either bend and fold (beta pleated sheet) or spiral. Secondary structure elements typically spontaneously form as an intermediate. Web the two most common secondary structural elements are alpha helices and beta sheets, though beta turns and omega loops occur as well.
