Chemistry - Biomolecules Question with Solution | TestHub

Primary structure of protein can be considered as linear polypeptide chain of amino acids, in which aminoacids are connected through peptide linkages. Different proteins have different sequence of amino acids intheir primary structure. For example insulin hormone is a protein which contains 51 amino acids. Hydrolysis of protein requires H₂O molecules. Each peptide linkage need one water molecule for its hydrolysis.

Now consider a decapeptide X (Mol. wt. 796), which upon complete hydrolysis produces Glycine (mol. wt.75), alanine and phenyl alanine. Glycine contributes 47% to the total weight of hydrolyzed product.
