What is a Peptide?

Peptides are short chains of amino acids, typically containing 2-50 amino acids. They are essentially small proteins that play many critical roles in the human body. Some key functions of peptides include:

• Cell signaling and communication: Peptides act as chemical messengers that help cells communicate with each other. They bind to specific receptors on cell surfaces to trigger cellular responses.
• Hormones: Many hormones like insulin, oxytocin, and glucagon are peptides that regulate various bodily processes like metabolism, reproduction, appetite, etc.
• Immune defense: Some peptides have antimicrobial properties and help defend the body against pathogens. For example, defensins are peptides that can kill bacteria by disrupting their cell membranes.
• Tissue repair and growth: Certain peptides stimulate tissue regeneration and cell growth. They are used to accelerate wound healing.

Now let's understand the structure of peptides:

• Peptides are made up of amino acids linked together by peptide bonds.
• The sequence and number of amino acids determine the peptide's structure and function.
• Shorter peptides are linear while longer peptides can fold into more complex 3D structures.
• The amino acids can be both natural and synthetic. Some common natural amino acids are glycine, alanine, valine, leucine, etc.

Some major classes of peptides include:

Class	Number of Amino Acids
Oligopeptides	2-10
Polypeptides	10-50
Proteins	Over 50

Small size and simple structure allow peptides to be easily synthesized chemically. This gives them significant advantages over protein-based drugs:

Advantage	Description
High potency	Peptides are very target specific and elicit powerful effects even at low doses.
Low toxicity	They are well tolerated with minimal side effects.
High stability	Chemical modifications make peptides resistant to metabolic breakdown.
High permeability	Peptides can penetrate cells easily due to their low molecular size.
Cost-effectiveness	Peptide drugs are cheaper to manufacture than protein therapeutics.

Peptide drugs are getting increasingly popular for treating various health conditions like diabetes, cancer, cardiovascular diseases, etc. Some examples include:

• Insulin for diabetes
• Liraglutide for weight loss
• Exenatide for diabetes
• Bivalirudin as an anticoagulant
