Chapter 21.2, Problem 1RQ

Interpretation Introduction

Interpretation:

Difference between protein and carbohydrates needs to be explained.

Concept introduction:

Protein − proteins are composed of the different types of amino acids and they are bonded together with the help of the peptide bonds.

Carbohydrate − carbohydrate is mainly composed of carbon oxygen and hydrogen. The glycosidic linkage present in different types of carbohydrates.

Answer to Problem 1RQ

The structure and monomer and linkage are different in proteins and carbohydrates.

Explanation of Solution

Property	Protein	Carbohydrate
Basic component	Protein is composed of amino acids.	Carbohydrate contains carbon, oxygen, and hydrogen.
Functional group	Amino, carboxylic, and side chain.	Ketones, aldehyde, polyhydroxy group.
Linkage	Peptide linkage	Glycosidic linkage
Class	Fibrous, globular	Monosaccharide, di, tri, and polysaccharide.

Conclusion

There is the main difference between protein and carbohydrate-

Carbohydrates are polyhydroxy aldehyde or ketones while proteins are polymers of different or same amino acids.

Proteins have peptide linkage, carbohydrates on the other hand have glycosidic linkages in higher forms.
