Check out this answer from Consensus:

Peptides are versatile molecules with a wide range of applications and benefits. From their use in pharmaceuticals and nutraceuticals to their role in cosmetics and agriculture, peptides continue to be a focus of research and development. Their diverse biological activities and potential for therapeutic use make them invaluable in improving health and quality of life.

By understanding the types, uses, and benefits of peptides, researchers and industry professionals can harness their potential to develop innovative solutions for various health and industrial challenges.

Peptides, short chains of amino acids linked by peptide bonds, have garnered significant attention in recent years due to their diverse biological activities and potential applications in various fields. This article explores the different types of peptides, their uses, and the benefits they offer.

Types of Peptides

Peptides can be broadly categorized based on their structure and origin. The two main structural classes are linear and cyclic peptides. Linear peptides are simple chains of amino acids, while cyclic peptides form a ring structure, which often enhances their stability and binding affinity5.

Bioactive Peptides

Bioactive peptides are specific protein fragments that have a positive impact on body functions or conditions and may influence health. These peptides are usually inactive within the parent protein and become active when released through enzymatic hydrolysis1 2 6. They exhibit a range of activities, including antioxidative, anti-inflammatory, anticancer, antimicrobial, immunomodulatory, and antihypertensive effects1 2 3.

Therapeutic Peptides

Therapeutic peptides are designed to target specific biological pathways and are used in the treatment of various diseases. They can serve as tumor-targeting agents, antimicrobial agents, and even as carriers for drug delivery4 5. Monocyclic peptides, a subtype of cyclic peptides, are particularly noted for their selective binding and stability, making them suitable for therapeutic applications5.

Uses of Peptides

Peptides have a wide array of applications across different industries, including pharmaceuticals, nutraceuticals, cosmetics, and agriculture.

Pharmaceuticals

In the pharmaceutical industry, peptides are used for their therapeutic properties. They are employed in the treatment of cancer, cardiovascular diseases, metabolic disorders, and infectious diseases. Peptides can act as hormones, enzyme inhibitors, and antimicrobial agents4 7 9.

Nutraceuticals and Functional Foods

Bioactive peptides are increasingly being incorporated into functional foods and nutraceuticals due to their health benefits. They can improve digestion, enhance immune function, and reduce the risk of chronic diseases. These peptides are derived from various food sources, including dairy, plant, marine, and animal products1 6 8.

Cosmetics

In the cosmetic industry, peptides are used for their anti-aging and skin-repairing properties. They can stimulate collagen production, improve skin elasticity, and reduce wrinkles. Peptides are also used in wound healing and skin regeneration products1 2.

Agriculture

Peptides are utilized in agriculture as biopesticides and growth promoters. They can enhance plant growth, protect against pathogens, and improve crop yield. Additionally, peptides are used in animal feed to promote health and growth3 5.

Benefits of Peptides

The benefits of peptides are vast and varied, making them valuable in multiple domains.

Health Benefits

Peptides offer numerous health benefits, including antioxidative, anti-inflammatory, and antimicrobial effects. They can help manage blood pressure, improve immune function, and support cardiovascular health. Peptides also play a role in reducing the risk of chronic diseases such as diabetes and cancer1 2 6.

Functional Benefits

Peptides are easy to digest and absorb, making them effective in delivering therapeutic benefits. Their ability to target specific cells and tissues enhances their efficacy and reduces side effects. Additionally, peptides can be synthesized chemically or produced through recombinant DNA technology, allowing for large-scale production2 3 7.

Industrial Benefits

In industrial applications, peptides contribute to the development of new products and technologies. They are used in the formulation of functional foods, pharmaceuticals, and cosmetics. Peptides also play a role in biotechnological advancements, such as the development of peptide-based vaccines and drug delivery systems8 9.
