Question

How does shape affect protein structure and function?

Answer 1

Hint: For main physiological processes of life proteins are essential and perform a function in the system of the human body and protein shape is responsible for its function as proteins are made up of amino acid subunits and each amino acid has their functions.

Complete answer:
1)Protein shape is critical to its function as it predicts that a protein can interact with other molecules or not and there is complexity in the structures of protein and to determine if there are four levels of protein structure that is primary, secondary, tertiary, and quaternary.

2)In the polypeptide chain, the primary structure of proteins has a unique sequence of amino acids that make up the protein as the final structure of protein depends on the sequence and insulin is the example of the primary structure of the protein.

3)Secondary structures are made by the interaction between the neighboring amino acids and when secondary structures fold among each other to form the three-dimensional shape then it is known as the tertiary structure of the protein and quaternary structure proteins are made by multi-subunit proteins.

4)Proteins have their unique amino acids and amino acid interactions specify the protein shape and this determines the protein function and the shape of the protein may alter if the protein can change its temperature, ph, and interaction between amino acids.

Note: On the basis of shape, proteins are of three types - Primary, secondary and tertiary proteins. Amino acid sequence does not change but if the shape of the protein changes then it leads to the dysfunction of protein and in this case, it will be considered as a denatured protein.
