The secondary structure of protein results from hydrogen bonds.
A protein is a complex and large biomolecule that is made up of amino acid residues.
In a protein macromolecule, all the amino acids are joined together by peptide bonds.
There are three different levels of protein structure: primary, secondary, and tertiary.
The secondary structure refers to the regular structure that has both intermolecular i.e hydrogen bonding and intramolecular forces.
Alpha helix along with β pleated sheets are the most widely known secondary structures of the protein molecule.
Both are held together by strong hydrogen bonds between carbonyl and amino groups.
