Question

Differentiate between Primary and secondary structure of proteins

Answer 1

Hint: The proteins are known to exist in four structures which are primary, secondary, tertiary and quaternary. The structures determine the function of the particular protein. The primary and secondary structure of proteins has different bonding between them.

Complete step by step answer:
-Proteins are peptide chains made up of amino acids. They are formed by two process called transcription and translation. After translation and post translational modifications, the peptide chains of amino acids are held together by peptide bonds. These are called simple protein structures which are also called primary structures.
-The simple proteins which undergo further tfolding form secondary structures. This secondary structure is stabilized by interactions like van der waal forces, hydrogen bonding, ionic bonds, etc.
The difference between the primary and secondary structure includes:

Primary structure	Secondary structure
Linear peptide with chains of amino acids.	Folded protein into alpha helices or beta sheets.
Linear appearance seen.	Seen as alpha helices and beta sheets.
Bonds present are only peptide bonds.	Bonds present are peptide bonds, hydrogen bonds, vanderwall bonds, etc.
Formed during the translation process.	Formed from the primary structure of proteins.
It is simple 2 D structure with only peptide bonds	The amines and carboxyl groups in the peptide chain interact and fold within to form secondary structure.

Note:
The primary structure and secondary structures can proceed to give tertiary structures and then quaternary structures. The bonds between the amino acids in primary structure and the hydrogen bonding give stability to the proteins.
