Six tripeptides that contain valine, tyrosine and glycine has to be named. Concept Introduction: Amino acid is a molecule that contains amino functional group and carboxyl functional group. Amino functional group is ( − N H 2 ) and carboxyl functional group is ( − C O O H ) and a R (alkyl) group is considered as side chain, when all these are bonded to same carbon atom. In protein the amide bond ( − C O − N H − ) can link together with two amino acids to form a peptide bond, by the release of water. A tripeptide results from the linkage of three amino acids through two peptide bonds. The peptide chain are named together with the first three letter of the amino acid joined with a hyphen.

Interpretation Introduction

Interpretation:

Six tripeptides that contain valine, tyrosine and glycine has to be named.

Concept Introduction:

Amino acid is a molecule that contains amino functional group and carboxyl functional group.

Amino functional group is (−NH2) and carboxyl functional group is (−COOH) and a R(alkyl) group is considered as side chain, when all these are bonded to same carbon atom.

In protein the amide bond (−CO−NH− ) can link together with two amino acids to form a peptide bond, by the release of water.

A tripeptide results from the linkage of three amino acids through two peptide bonds.

The peptide chain are named together with the first three letter of the amino acid joined with a hyphen.
