What are Peptides?
Definition: Peptides are short chains of amino acids, typically consisting of 2 to 50 amino acids. Building Blocks of Proteins: They serve as the building blocks for proteins, playing a fundamental role in protein structure and function.
Where are Peptides Found?
Natural Sources: Peptides are found naturally in organisms, including animals, plants, and microorganisms.
Tissue Distribution: They are present in various bodily tissues, such as muscles, skin, and organs.
Applications and Research Areas:
Therapeutic Applications: Peptides have diverse therapeutic applications, such as peptide-based drugs for various medical conditions.
Peptide-Based Vaccines: Peptides are utilized in the development of peptide-based vaccines to stimulate the immune system against specific diseases.
Drug Delivery Systems: Peptides play a role in drug delivery systems, aiding in targeted and controlled release of medications.
Peptide Research: Ongoing research explores the potential of peptides in various fields, including medicine, biotechnology, and materials science.
What Functions do Peptides Serve?
Signaling Molecules: Peptides function as signaling molecules, transmitting information between cells and regulating physiological processes.
Hormones and Neurotransmitters: Some peptides act as hormones, influencing bodily functions, while others act as neurotransmitters, facilitating communication in the nervous system.
Enzymes and Enzyme Inhibitors: Certain peptides act as enzymes, facilitating biochemical reactions, while others serve as enzyme inhibitors, regulating enzyme activity.
Antimicrobial and Defense Agents: Peptides can exhibit antimicrobial properties, helping to protect organisms against pathogens and infections.
Cell Regulation: Peptides participate in cell regulation, including cell growth, differentiation, and apoptosis (programmed cell death).
