Vedclass · Answer

(C) Tripeptides are polymers of amino acids in which three individual amino acid units,called residues,are linked together by amide bonds (peptide bonds).Since we have $3$ distinct amino acids (glycine,alanine,and phenylalanine),the number of possible tripeptides is given by the number of permutations of these $3$ distinct items.The number of arrangements is $3! = 3 	imes 2 	imes 1 = 6$.Therefore,there are $6$ different ways to link these amino acids.

How many tripeptides can be prepared by linking the amino acids glycine,alanine and phenylalanine?
