Hello readers! We hope you all are doing great. In today’s article, we will discuss peptide monomer. Do you know? Your body makes peptide polymers and they are strings of amino acids. Peptides are also synthesized in laboratories. Lade-made peptides can copy some of those found in your body. Some of them are used in medications for conditions ranging from multiple sclerosis to diabetes. There are many peptides and each of them has a different job in your body. They benefit the human body in various ways. Like anti-aging, collagen peptides help make collagen and elastin proteins in healthy skin. Let’s come back to our peptide monomer

What Is Peptide Monomer? 

The peptide monomer is an amino acid. So, amino acids are molecules that are used by all living things, including humans, to make proteins. Protein synthesis is a very important yet essential process in the human body, as proteins need to generate and replicate genetic information. Your body needs 20 different kinds of amino acids to generate protein and to function correctly. Nine out of 20 are called essential amino acids, therefore, they must be consumed through the food you eat. They can be found in a variety of foods like eggs, beef, meat, and dairy products. 

In short, amino acids are the building blocks of proteins. Proteins are long threads of chains of amino acids. In your body, there are more than thousands of different proteins that each have important jobs. Each protein has its own arrangements of amino acids. The different arrangements of amino acids make the proteins take different shapes and have different functions in your body. 

Now, you got peptide chains are composed of what monomer. Let’s know the properties of peptide monomers in detail.

Properties Of Peptide Monomer 

The properties of peptide monomers are, 

  • Peptide monomers, which as amino acids have very high boiling and melting points.
  • They are white crystalline solid substances essential in protein synthesis.
  • Protein contains different sequences of amino acids
  • The sequins of amino acids decide the shape and functions of proteins.
  • There are 20 standard amino acids and they all are used in protein synthesis.
  • Most amino acids are soluble in water and are insoluble in an organic solvent.
  • A few amino acids taste sweet, some are tasteless, and some are bitter in taste.
  • Amino acids are colorless, non-volatile, and decompose at temperatures above 200 deg C.

Peptide Structure And Function 

To completely understand peptides you should know about their structure and function. Let’s have a look.  

Peptide Structure 

The structure of peptide polymer contains two or more amino acids joined through amide formation involving the carboxyl group of each amino acid and the amino group of the next amino acid. The chemical bond between the nitrogen (N) and Carbon(C) atoms of each amide group is called a peptide bond. What kind of reaction forms a peptide bond? Well, peptide bonds are formed by biochemical reactions, when a water molecule joins the amino group of an amino acid to the carboxyl group, it extracts the water molecule of the next. The linear sequence of amino acids within a protein chain is considered the primary structure of the protein. 

Peptide Function 

Do you know? Peptides play a very crucial role in your body. Vasopressin or antidiuretic hormone is a peptide hormone that is secreted in the hypothalamus, which is a small portion of the brain that is located at the base of the brain. Vasopressin has a couple of functions. It is responsible for regulating the amount of water present in the fluid space around calls. It does this by causing the kidneys to absorb water. Vasopressin is also a vasoconstrictor when ‘it is used in large amounts, which means it causes the blood vessels to constrict, leading to an increase in blood pressure. 

Facts About Peptide 

Facts about peptides are, 

  • More than thousands of peptides are found in the human body
  • Peptides can be made in a laboratory.
  • Peptides are short strings of amino acids, typically of 2 to 50 amino acids.
  • Amino acids which are monomers of peptides are also monomers of proteins, but proteins contain a long chain of amino acids.
  • As peptides contain a short chain of amino acids they may be easier for the body to absorb than proteins.
  • Without peptides, human skin is less intact which can lead to loss of firmness and the appearance of wrinkles.
  • Peptides have a lower molecular weight and a higher number of ionizable groups.
  • Peptide hormones help in blood sugar regulation.

Is Peptide A Monomer Or Polymer?

Proteins (polymers of ~50 amino acids or more) and peptides (shorter polymers) are formed when the amino group of one amino acid monomer reacts with the carboxylate carbon of another amino acid to form an amide linkage, which in protein terminology is a peptide bond.

What Is The Monomer Of Peptides And Proteins?

Amino acids are the monomers that make up proteins. All proteins are made up of different arrangements of the same 20 amino acids.

Is A Peptide Bond A Monomer?

Peptide bonds (also known as amide bonds) are the bonds that are found between two monomer units of amino acids in a polypeptide chain.

What Are The Monomers For A Peptide Protein Polymer?

For example, proteins are composed of monomers called amino acids. They are linked together to form a polypeptide chain, which folds into a three dimensional (3D) structure to constitute a functional protein (Figure 1).


A monomer peptide called amino acid is also a monomer of protein. Peptides play a major role in medication as they are used to create drugs to treat a variety of diseases. 

There are over 100 peptide drugs in the United States, which are used to treat conditions such as high blood pressure, multiple sclerosis, and type 2 diabetes. And more keep coming. Unlike some cosmetics that are supplements, these drugs have been well-researched and are tightly regulated by the FDA. Now, you have a wholesome idea of peptide monomer, structure, and function.
