Peptide vs. Enzyme: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on November 22, 2023
"Peptide" is a molecule formed by linking amino acids; "enzyme" is a protein that catalyzes biochemical reactions.

Key Differences

Peptides are short chains of amino acids linked by peptide bonds, serving various functions in the body. Enzymes, which are also made up of amino acids, act as catalysts in speeding up biochemical reactions.

The structure of a peptide is simpler and smaller compared to enzymes, which have complex, larger structures. Enzymes are functional proteins that are crucial for metabolic processes.

Peptides play roles in signaling and regulation in the body, often acting as hormones. Enzymes, however, are involved in facilitating reactions, like digestion and cellular metabolism.

Enzyme

A protein produced by a living organism, capable of catalyzing a chemical reaction. Almost all processes in living organisms require some form of enzyme to cause the reactions to occur at a rate sufficient to support life. There are a very wide variety of enzymes, each specifically catalyzing a different chemical reaction, the sum of which cause the bulk of the physiological changes observed as life processes. Enzymes, like most proteins, are synthesized by the protein-synthetic mechanism of the living cell, at special sites on ribosomes, using the genetic information in messenger RNA transcribed from the genetic instructions stored as nuleotide sequences in the DNA (or in some viruses, the RNA) of the genome. Some examples of enzymes are: pepsin, diastase, rennet, DNA polymerase, invertase, glucose oxidase, protease, and ribonuclease. There are many other types of enzyme.
