What Are Peptide Hormones?

November 19, 2023

Peptide hormones are short chains of amino acids that act as signaling molecules in the body. They play essential roles in various physiological processes from growth and development to metabolism and immune function.

The story of peptide hormones began in the early twentieth century. The first peptide hormone to be identified was secretin, discovered by British physiologists Ernest Starling and William Bayliss in 1902. They found that secretin could stimulate the pancreas to release digestive enzymes. 

The next few decades saw the discovery and isolation of other peptide hormones. Insulin, discovered by Frederick Banting and Charles Best in 1921, was groundbreaking because it led to treatments for diabetes, a condition that had been essentially untreatable until this point.

Potential Uses for Health and Wellness

Peptide hormones are used in a number of wide-ranging applications, including:

Medical Treatments

In the medical field, peptides are harnessed for therapeutic treatments, addressing conditions ranging from diabetes to osteoporosis.

Insulin is an example of how peptide hormones impact medicine. It revolutionized the treatment of diabetes by regulating blood sugar and has been a lifesaver for millions of people with the disease. 

Another example is growth hormones, which treat children with growth deficiencies. Oxytocin is another drug used to induce labor in pregnant women. Calcitonin, derived from salmon, inhibits osteoclast activity that breaks down bone and is used in the treatment of osteoporosis.

Medical peptide hormones are regulated like other drugs, requiring prescriptions and oversight by medical professionals. Countries have strict protocols for the approval of therapeutic peptides. For instance, before a new insulin variant reaches the market, it undergoes peptide bioregulator reviews to ensure safety and efficacy. 

Performance Enhancement 

Some athletes and bodybuilders use peptide hormones to try to enhance muscle growth, muscle repair, and athletic performance, although this is a controversial practice. Human growth hormone (commonly known as ‘HGH’) is a peptide hormone sometimes misused for its muscle-building and recovery properties. 

Anti-Aging and Wellness

Peptides have been researched for their potential anti-aging properties and ability to enhance overall wellness. Peptides like collagen are often promoted for skin health and are found in many skincare products. They’re believed to improve skin elasticity and reduce wrinkles. 

Glutathione is another peptide explored for its antioxidant properties, promoting overall health and wellness.

How Peptide Hormones are Regulated

Peptide hormones are subject to various national and international regulations because of their therapeutic potential and potential for abuse, which often prompts people to wonder whether peptides are legal

Certain peptides used frequently in athletics have been monitored or restricted by regulatory bodies like the World Anti-Doping Agency due to their potential performance-enhancing properties. However, it’s crucial to note that not all peptides are under scrutiny and are used widely in different applications.

As research continues, the understanding and positive applications of peptides are set to expand. Consumers and professionals alike should approach peptides with a balance of enthusiasm and informed caution.

The Future of Peptide Hormones

Scientists are now at the frontier of designing peptides with specific functionalities, which could lead to more targeted therapies with fewer side effects. With advancements in molecular biology and peptide synthesis, more peptide hormones are being developed and tested for various medical conditions. 

Advancements may also allow for the treatment of diseases that currently have limited options. For example, peptides are being researched for their potential to treat neurodegenerative diseases such as Alzheimer’s disease. In the future, custom-designed peptides could target particular conditions or even individual tumors in cancer, reducing the impact on healthy cells and tissues.

One challenge with peptide hormones is their delivery because they can be broken down in the digestive system. Innovations in delivery methods, such as nanoparticle carriers or specialized injections, can improve the efficacy of peptide-based treatments.

Scientists are also working on oral delivery systems for insulin, which would be a major breakthrough for diabetes patients, eliminating the need for injections. Patches or inhalers are other novel delivery methods under exploration that might improve the patient experience by offering more comfortable and efficient ways to administer peptide hormones.
