A clear guide to the key terms used in peptide discussions, so you can read and understand information without confusion.
Peptides are often described using scientific language. Understanding basic terminology makes it easier to navigate research, product descriptions, and educational materials.
Key Terms
- Amino acids
The building blocks of peptides and proteins. - Peptide chain
A sequence of amino acids connected by peptide bonds. - Protein
A longer chain of amino acids. Proteins are larger and more complex than peptides. - Signaling molecule
A substance that sends messages between cells. - Bioavailability
How much of a substance is absorbed and used by the body. - Half-life
The time it takes for a substance to reduce by half in the body. - Receptor
A structure in or on a cell that peptides bind to. - Mechanism of action
How a peptide works in the body.
