What is a peptide?
Understand the Problem
The question asks for a definition of the term 'peptide' in a biological context. This involves understanding the basic chemical structure and biological significance of peptides.
Answer
Peptides are short chains of amino acids linked by peptide bonds.
Peptides are short chains of amino acids, typically ranging from 2 to 50 amino acids, linked together by peptide bonds. They're essentially smaller versions of proteins and play significant roles in various biological functions.

More Information
Peptides are involved in numerous biological processes, and are used in skincare and medicine. They can be naturally found in the body, ingested through food, or taken as supplements.
Tips
A common mistake is thinking peptides and proteins are the same. Peptides are smaller than proteins. Also, the exact number of amino acids that differentiate a peptide from a protein can vary.
