Chapter 24.3, Problem 17LC

Interpretation Introduction

Interpretation: The basis of determining the differences in the properties of peptides and proteins is to be explained.

Concept introduction: The bond between two amino acids in a peptide chain is referred to as a "peptide bond." Peptide bonds join amino acids by linking one amino acid's carboxyl group to another's amine group, resulting in the release of water.

Answer to Problem 17LC

Proteins and peptides have different properties based on the length of their structure or the number of amino acids. Proteins are made up of more than $50$ amino acid units, while peptides are made up of $22$ to $50$ amino acid units.

Explanation of Solution

Amino acids are the fundamental components of both proteins and peptides. The only difference between them is the length of their structure or the number of amino acids. Peptides are generally built from $22$ to $50$ amino acid units, whereas proteins are built from more than $50$ amino acid units.

Conclusion

Proteins and peptides have different properties based on the length of their structure or the number of amino acids. Proteins are made up of more than $50$ amino acid units, while peptides are made up of $22$ to $50$ amino acid units.
