Amino acids are monomer of protein and these aminoacids are connected by peptide bond. A
decapeptide (Mole wt. 796) on complete hydrolysis gives glycine (Mole wt. 75), alanine and
phenylalanine. Glycine contributes 39.14% to the total weight of the hydrolysed products.
The number of glycine units present in the decapeptide is :
