Two statements, one Assertion and the other Reason are given. Choose the right option. Assertion: Insulin is called a protein whereas Glycyl alanine is not called a protein Reason: A polypeptide with amino acid residue less than 100 can also be called as a protein if it has a well-defined conformation of a protein.

Step-by-step solution

Insulin is a hormone composed of 51 amino acids arranged in two polypeptide chains linked by disulfide bonds. It is classified as a protein because it possesses a specific, well-defined three-dimensional conformation essential for its biological activity. Therefore, the assertion that insulin is called a protein is correct. Glycyl alanine is a dipeptide consisting of only two amino acid residues. It lacks the complex, well-defined three-dimensional structure required to be classified as a protein. Thus, it is not c
