What are Peptides?

Cytokine - amino acid that allows cells to communicate with each otherBefore we dive into what is Peptide Therapy, let’s first understand what are Peptides. Peptides are naturally occurring biological molecules. Apparently, all creatures right from simple viruses to human beings have complex structures in their bodies made up of 20 different amino acids called proteins.

While studying them, a class of substances consisting of similar amino acid chains but different from proteins was found by biologists. The difference between peptide and protein is that Peptide is a short chain that can contain two or more amino acids, while a protein is a complex structure that can consist total of 50 or more amino acids.

Your body uses these amino acids for turning over and creating new cells, which are necessary for maintaining good health and carrying out various functions. In fact, more than 7000 Peptides have been found within every cell and tissue of the human body. They play a crucial role in how your body functions and responds.

While some peptides take care of the immune function, some assist with sleep, weight management, healing, etc, and others act like hormones that carry information from one tissue to another through blood. Low levels of Peptides in your body can result in causing many health problems. This is where Peptide therapy steps in.

What is Peptide Therapy?

The administration of Peptides is usually done through injectionsPeptide Therapy has recently come into the spotlight for its proven ability to restore and improve health. Peptides, which are the chain of amino acids carry out various necessary functions like immunity building, regulating metabolism, growth, development, etc in human beings.

Adequate Peptide levels are essential for achieving optimal health. Peptide therapy restores the number of peptides and stimulates the cellular regrowth system. It has high potency and specificity. These are diverse chemicals low in toxicity.

The administration of Peptides is usually done through injections, but some peptides can also be administered through other methods.There are various types of peptides, each has its unique property and can be used to treat different conditions.

History and Development of Peptide Therapy

In the year 1902, Starling and Bayliss found secretin by demonstrating that when acid arrives from the stomach, it liberates a chemical messenger that travels through the blood and triggers the pancreas to secrete pancreatic juice. This was the first time that humans identified a Peptide and understood its role in endocrinology.


In the year 1931, Ulf von Euler and John H’. Gaddum found SP or Substance P in the extract of a tissue that was responsible for causing intestinal contraction in Vitro. This discovery influenced and prompted scientists to take a closer look at the Peptides and their effects on the nervous system. Such substances were then termed ‘neuropeptides’.


Later in the year 1953, Vincent Du Vigneaud performed research on the hormone ‘Oxytocin’ that is involved in reproduction and sexual intimacy in humans and animals. He successfully isolated the substance and discovered its chemical composition creatingthe history of identifying the first peptide hormone. Later, he also succeeded in creating this hormone artificially as well.


Further, between the years 1959 and 1963, Robert Bruce Merrifield revolutionized the field of organic chemistry with his invention of Solid-Phase Peptide Synthesis (SPPS). This groundbreaking invention changed the way scientists synthesize peptides, allowing more efficient production of peptides.

Following that in the year 1963,Chinese scientists made a breakthrough by synthesizing insulin successfully. This was the first synthetically produced peptide. Peptides further became the hotspot for researchers and led to the discovery of enkephalin and opioid peptides and many more were found as well as synthesized later.

Biochemists have been synthesizing peptides for 40+ years now. With the rapid development of biochemical technology and molecular biology, peptide research, and production have made incredible progress and have been used as a treatment option for a variety of health concerns.

Angiotensins – These peptide hormones are part of your renin-angiotensin system. They regulate blood pressure and stimulate the release of aldosterone from your adrenal cortex, which help kidneys to retain sodium.

Vasopressin (antidiuretic hormone) – This peptide hormone secretes in the hypothalamus, a small portion of your brain located at the base of it. It carries out a couple of functions, such as regulating the water amount in the fluid space around cells, and also acts as a vasoconstrictor that causes the narrowing of blood vessels.

Oxytocin – This peptide is made up of nine amino acids and is produced by the pituitary gland in your brain. It is also known as the ‘love hormone’ or ‘cuddle hormone’ as it is released when people snuggle or bond socially. Oxytocin plays several roles such as causing uterus contractions during childbirth and promoting the milk ejection reflex during breastfeeding.

Defensins – These peptides are mainly active in your immune system and are referred to be antimicrobial, thereby supporting and enhancing the wound healing process.
