What Are Peptides?
Peptides are short chains of amino acids, typically consisting of 2 to 50 amino acids, linked together by peptide bonds. These molecules are smaller than proteins, which are long chains of amino acids. Peptides are naturally occurring in the human body and serve various biological functions, including acting as hormones, enzymes, and signaling molecules.
Key Characteristics of Peptides
- Smaller in size compared to proteins
- Highly specific in their biological functions
- Easily synthesized and modified in laboratories
Natural vs. Synthetic Peptides
While natural peptides are produced by the body or extracted from natural sources, synthetic peptides are engineered in laboratories for specific applications. Synthetic peptides are widely used in research, medicine, and commercial industries.
How Do Peptides Function in Biological Systems?
Peptides play a crucial role in regulating and facilitating numerous biological processes. They act as messengers, communicating signals between cells and tissues to maintain homeostasis and enable proper bodily functions.
Examples of Biological Functions
- Hormonal regulation (e.g., insulin)
- Immune system modulation
- Cell signaling and communication
Why Are Peptides Important?
The specificity and efficiency of peptides in targeting certain biological pathways make them invaluable in therapeutic and diagnostic applications. Their ability to interact with receptors and enzymes with high precision minimizes side effects and enhances efficacy.
Therapeutic Applications of Peptide Science
