Peptide

A peptide refers to a short chain of amino acids that are interconnected by chemical bonds known as peptide bonds. These compact chains play a pivotal role in the formation of proteins, serving as the foundational building blocks for these complex biological molecules. Peptides exhibit diversity in their classification, primarily based on three key criteria: the number of amino acids composing the chain, their origin (plant or animal), and their functions within the body.

In the context of collagen, a protein of significant importance, it is composed of three distinct polypeptide chains that come together to create its characteristic triple-helix structure. This unique arrangement of polypeptide chains in collagen contributes to its remarkable strength and structural integrity, making it a crucial component in various tissues and organs throughout the body. Understanding the role of peptides, such as those found in collagen, is essential for appreciating their significance in the intricate web of biological processes that govern human health and function.
