Structural formula of bradykinin is to be drawn. Concept introduction: Many amino acids are linked together through amide bonds to form a biologically large molecule known to be proteins. Amine functional group is ( − N H 2 ) and carboxyl functional group is ( − C O O H ) and a R group is considered as side chain, when all these are bonded to same carbon atom. In protein the amide bond can link together with two amino acids to form a peptide bond. Primary structure of protein is a sequence in which the amino acids linked by peptide bond in a protein. Bradykinin is a 9-amino acid peptide chain. The Sequence is Arg-Pro-Pro-Gly-Phe-Ser-Pro-Phe-Arg .

(a)

Interpretation Introduction

Interpretation:

Structural formula of bradykinin is to be drawn.

Concept introduction:

Many amino acids are linked together through amide bonds to form a biologically large molecule known to be proteins.

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

In protein the amide bond can link together with two amino acids to form a peptide bond.

Primary structure of protein is a sequence in which the amino acids linked by peptide bond in a protein.

Bradykinin is a 9-amino acid peptide chain. The Sequence is Arg-Pro-Pro-Gly-Phe-Ser-Pro-Phe-Arg .
