Balance diet is vital for the proper functioning of your body, and proteins and peptides contribute to be an essential part of it. Proteins and peptides are not only helpful in building muscles but also provide many therapeutic benefits. Though many people think both are the same things, they are very different. Proteins are long polymers of peptides and have a well defined 3D structure. Proteins carry the essential function of cell signaling and provide shape to the cell. Likewise, many beneficial features are given by peptides, which we will see in the following article and which types of foods are high in peptides and their benefits

What are peptides?

The word Peptide is derived from the Greek word ‘peptós,’ which means ‘digested.’ Peptides are small polymeric chains of amino acids, having 2-50 amino acids, linked together by peptide bonds. These are building units of proteins and fulfill the requirement of essential amino acids in your bodies. They form naturally in bodies by the process of translation of genetic material (DNA).

Sources of Peptides

Different types of peptides carry specific functions of their own, and all these have various sources. Our body requires all different kinds of peptides for its proper functioning. The most common cause of these different peptides is the food you consume.

PeptidesSources
 LunasinSoybean, Barley
CollagenMeat, Egg, Fish
LactotripeptidesMilk Products
Beefy Meaty PeptideBeef, Meat
Soymorphins Soybean
ArbutinWheat, Bearberry, Cranberry

The only focus is on the biologically active Peptide, which you can obtain from plant or animal sources. Apart from a biological source, synthetic peptide supplements are also available in the market for fulfilling the additional requirement of peptides in your bodies. 

Collagen is the most abundant Peptide in the body, making about 25 to 30 percent of all protein content.

Benefits of Peptides

From fulfilling the requirement of essential amino acids to the building of muscles, Peptides carry out many crucial bodily functions. Apart from these crucial functions, peptides also have many therapeutic effects.

Reduce Inflammation

Inflammation is the body’s innate response to injuries, which results in leaking of different immune cells like Neutrophils, Basophils, Mast cells, Macrophages, and others. Though it is the body’s innate response, excessive inflammation can lead to chronic diseases. Chronic inflammation can also result in developing cancer of different types. So, it is crucial to regulate the condition of inflammation. Although there are many synthetic anti-inflammatory drugs available in the market, they all have some side effects. Therefore people are switching to the naturally present compounds for a safer life.  

According to research, bioactive peptides like Casein (obtained from milk), IRW, and IQW (Egg peptides), etc., have shown sound results in reducing inflammatory effects by different means. Milk peptides tend to inhibit the c-Jun N-terminal kinase pathway, which directly reduces the impact of inflammation in vitro conditions. On the other hand, egg peptides take part in modulating the NF-κB pathway, which down-regulates cytokines’ effects inducing an inflammatory response. Though different peptides take different paths, they achieve the common goal reducing the inflammatory impact on our body. 

Reduces the chance of chronic disease

Consumption of bio-active peptides results in many health benefits. Moreover, it reduces the chance of many chronic diseases like cardiovascular diseases, type 2 diabetes, obesity, immune disorders, etc. Because of all the beneficial qualities, research on peptides in this field has increased significantly over the last decade. With the help of different scientific approaches, bio-active peptides are isolated from the peptide synthesis services food sources, which possess different therapeutic functions like anti-hypertensive, anti-cancerous, immunomodulatory, hypolipidemic, and many others. Peptides like lunasin and soymorphins (soybean peptides) even show more than one of the properties alone. Because of this research, U.S.A approved the health claim of soybean, reducing the chance of coronary heart diseases. 

Act as an antioxidant

According to studies, bioactive peptides obtained from different sources possess antioxidant properties—the most common source of getting these antioxidant peptides through plants. Many types of research show the reverse effects of antioxidants toward various diseases. Antioxidants are useful as anti-cancer agents as well. Therefore, a lot of research focuses on the therapeutic effects of antioxidants on cancer cells. These antioxidant properties of the Peptide can also be useful in both in vitro and in vivo preservation activities. The Peptide can be helpful as an ingredient in the food, resulting in the healthy life of the consumer and in increasing the shelf life of the food. 

Act as an anti-aging factor

Our skin ages because of different factors like UV radiation, pollution, stress, and hormones. Wrinkles are the main indications of skin aging, and to hide that, we use many cosmetic products. But, every cosmetic product has its side effects. Mostly arbutin and EFG are used in cosmetic products as an anti-aging factor, but these synthetic substances show many adverse effects on the skin. To be safe from the side effects and have wrinkle-free skin, we can use peptides like AIMP1-derived Peptide. According to studies, AIMP1-derived peptide treatment increases the collagen synthesis in the skin and inhibits the synthesis of melanin by reducing tyrosinase activity. Both of these factors give white and wrinkle-free skin.

Conclusion

Apart from serving as a nutrient, peptides also carry out many physiological functions. With these many benefits, peptides can revolutionize our pharmaceutics and supplements. But it is not an easy process to isolate or produce peptides in a mass quantity. Therefore the commercial activities of the peptides are on hold.
