1. Peptides as Signalling Molecules

Peptides often function as signalling molecules that facilitate communication between cells. They can act as hormones, neurotransmitters, or growth factors, helping regulate various physiological processes.

2. Receptor Binding and Activation

Peptides exert their effects by binding to specific receptors on the surface of cells. This binding triggers a cascade of intracellular events, often referred to as signal transduction, which leads to a biological response.

3. Specificity and Targeting

One of the key advantages of peptides is their high specificity. They are designed to interact with particular receptors, reducing the likelihood of off-target effects. This makes them valuable tools in controlled research environments.

4. Cellular Responses

Once a peptide binds to its receptor, it can initiate a range of cellular responses, including gene expression, enzyme activation, or changes in cell behaviour. The exact response depends on the peptide and the target cell type.

5. Applications in Research

Peptides are widely used in research to study cellular pathways, receptor interactions, and biological mechanisms. Their predictable behaviour and specificity make them ideal for investigating complex systems.
