Collection: Peptides

Peptides are short chains of amino acids linked together by peptide bonds. They are smaller than proteins, typically composed of 2 to 50 amino acids. Peptides play essential roles in various biological functions, including:

• Signaling molecules: Many peptides act as hormones or neurotransmitters, such as insulin (which regulates blood sugar levels) or endorphins (which relieve pain).
• Antimicrobial agents: Some peptides, known as antimicrobial peptides (AMPs), help protect organisms from infections by killing bacteria, fungi, or viruses.
• Building blocks: Peptides are precursors to proteins, which are larger molecules made up of one or more peptide chains folded into complex structures.
• Enzymatic function: Certain peptides can act as enzymes, speeding up biochemical reactions in the body.

Peptides are often synthesized for medical and cosmetic applications, such as in anti-aging treatments, drug development, and vaccine creation. They can be natural or synthetic and are being explored for their therapeutic potential due to their specific action on cellular receptors.
