Chapter 21.1, Problem 2RQ

Interpretation Introduction

Interpretation:

The property of the side chain on an amino acid needs to be explained.

Concept introduction:

Proteins are macromolecule and they are composed of the amino acid. The amino acids in protein are covalently bonded to each other to form polypeptides. These proteins can fold to form a specific 3D shape. As per the amino acid sequence, there are different shapes of proteins. The molar mass of the protein depends on the chain attached to the amino acid.

Answer to Problem 2RQ

The hydrophobic or hydrophilic quality affects the three-dimensional structure of the proteins.

Explanation of Solution

The proteins are composed of different types of amino acids. The side chain and groups bonded in a fixed to stabilize the structure of the proteins. The backbone of protein is made by the side chains of the amino acids. The helical structure of the proteins formed with the help of the amino acid chain interaction. The stabilizing and electrostatic interaction of the proteins depends on the side chains.

The side chain affected the polarity and water-loving and hating properties of proteins.

Conclusion

A three-dimensional structure of the proteins is formed with the interaction of the side chains of the amino acids. The polarity and hydrophobic or hydrophilic properties of the proteins define with the help of the side chain of the amino acid.
