Secondary Structure of Proteins
Secondary structure of a protein refers to the folding patterns of the polypeptide chain. This structure is primarily determined by hydrogen bonding between amino acids along the polypeptide chain.

Key Points:
- The most common secondary structures are alpha helices and beta sheets.
- In an alpha helix, the polypeptide chain is coiled like a spring.
- In beta sheets, the polypeptide chain folds back and forth on itself.
- These structures are stabilized by hydrogen bonds between the backbone atoms of the amino acids.

Folding Patterns of Polypeptide Chain
The folding patterns of the polypeptide chain in a protein determine its secondary structure. These patterns are essential for the protein to maintain its specific shape and function. The secondary structure is crucial for the overall three-dimensional structure of the protein.

Hydrogen Bonding
Hydrogen bonding plays a significant role in stabilizing the secondary structure of proteins. The hydrogen bonds form between the amino acid residues, specifically between the hydrogen of the amino group and the oxygen of the carbonyl group. These bonds help maintain the structural integrity of the protein.
In conclusion, the secondary structure of a protein is defined by the folding patterns of the polypeptide chain, primarily stabilized by hydrogen bonding between amino acids. This structure is essential for the overall function and stability of the protein.

The secondary structure of a protein refers to regular folding patterns of continuous portions of the polypeptide chain. It is primarily determined by hydrogen bonding interactions between the amino acid residues of the chain. The two most common types of secondary structure are alpha helices and beta sheets.

Read the following passage to answer the following questions:Proteins are polypeptide chains made up of amino acids. There are 20 types of amino acids joined together by peptide bond between amino and carboxylic group. There are two kinds of amino acids, Essential amino acids and Non-essential amino acids. The Primary structure of protein is the linear sequence of amino acids in a polypeptide chain. The first amino acid of sequence is called N-terminal amino acids and last amino acid of peptide chain is called C-terminal amino acids. The secondary structure proteins forms helix. There are three types of secondary structure: a helix, P pleated and collagen helix. In tertiary structure long protein chain is folded upon itself like a hollow woollen ball to give three-dimensional view of protein.
