Chapter 25, Problem 63PP

Interpretation Introduction

Interpretation:

Total number of acyclic tripeptides containing L-leucine, L-methionine and L-valine need to be found out.

Concept introduction:

Peptides are formed when condensation reaction happens between amino acids forming amide linkage or peptide linkage.  If the peptide formed has two amino acid residues then it is known as dipeptide.  If it has three it is known as tripeptide and the list goes on.  There are various combinations in which the amino acid residue can be arranged to give different peptides.  To simply identify the total number of peptides that can be formed with the given amino acids, we can use the permutation and combinations.

To identify : To identify all the possible acyclic tripeptides containing L-leucine, L-methionine and L-valine.
