Peptide vs. Enzyme: What's the Difference?

A molecule composed of two or more amino acids.

A protein that accelerates chemical reactions.

A compound participating in various biological functions.

Catalysts in biological systems.

Often used in pharmaceuticals and biotechnology.

Involved in digestion, metabolism, and many other processes.

A short chain of amino acids linked by peptide bonds.

Can be inhibited or activated under different conditions.

A segment of a protein molecule.

Specific to certain substrates and reactions.

Any of various natural or synthetic compounds containing two or more amino acids joined by peptide bonds that link the carboxyl group of one amino acid to the amino group of another.

Any of numerous compounds that are produced by living organisms and function as biochemical catalysts. Some enzymes are simple proteins, and others consist of a protein linked to one or more nonprotein groups.

(organic compound) Any of a class of organic compounds consisting of various numbers of amino acids in which the amine of one is reacted with the carboxylic acid of the next to form an amide bond.

(biochemistry) A globular protein that catalyses a biological chemical reaction.

(chemistry) The peptide bond itself.

(Christianity) leavened bread, as opposed to azyme

Amide combining the amino group of one amino acid with the carboxyl group of another; usually obtained by partial hydrolysis of protein

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.

Any of several complex proteins that are produced by cells and act as catalysts in specific biochemical reactions
