Proteins, along with carbohydrates and fatty acids, are one of the most essential building blocks of a human cell. Since amino acids are the basic constituent of these compounds, their production and regulation become vital for the proper functioning of the body. Among the various types of amino acids, serine is an important chemical that is used for the biosynthesis of proteins. As an α-amino acid, it plays a major role in the production of various enzymes, fatty acids, and muscle tissues. Moreover, it acts as a precursor to other amino acids such as glycine and cysteine. In the past few years, L-serine has especially become quite popular in the healthcare and cosmetics industries.
Increased usage to treat brain disorders creating new investment opportunities
Recently, Allied Market Research published a report on the serine market which highlighted that the industry is expected to gather a revenue of $60.5 million by 2032. The sector accounted for $33.3 million in 2022 and is estimated to rise at a CAGR of 6.2% during 2023-2032. The rising use of serine in manufacturing health supplements and wellness products is one of the primary factors impacting the landscape positively.
In the early 2000s, several medical studies were commissioned by multiple research institutes to study the inhabitants of the Okinawa Island of Japan. The culturally and ethnically diverse population was known for their high lifespans, typically above 80, which is much higher than other communities living in the region. The studies showed that the diet of Okinawans consisted of fish, green vegetables, soy, seaweed, and other such food items that have high L-serine content. Medical researchers, thus, concluded that regular consumption of serine-rich foods was the main reason behind the longevity of an average Okinawan individual.
In the subsequent years, L-serine has become quite popular in the healthcare sector due to its various medical benefits. Most importantly, this ingredient is used as a neuroprotective agent to support different brain functions. Its ability to synthesize phosphatidylserine, an important component of brain neurons, makes it an ideal compound for modulating signals between the nerve cells. Recently, Pharmacy Times, a leading pharmaceutical research journal, featured a research paper that highlighted that it helps boost brain power and memory. The article further adds that pharmaceutical companies are developing drugs made from L-serine and phosphatidylserine for treating different ailments including Parkinson’s, Alzheimer’s, and dementia.
Along with this, L-serine is an important part of the tryptophan production process. Tryptophan is an amino acid responsible for producing serotonin, thus aiding in relieving stress and anxiety. Hence, L-serine drugs are regularly used to treat depression and other mental health disorders as they provide a calming effect to the brain. Moreover, this amino acid also enhances sleep initiation and maintenance processes, thereby improving the cycles and routines.
Increased applicability of L-serine drugs in cancer therapeutic intervention
Apart from its positive impact on the brain, serine also helps treat cardiovascular diseases and other lifestyle ailments such as cancer and diabetes. A lab study done in 2008 revealed that L-serine health supplements assist in the manipulation of the conduction of nerve impulses in the heart, blood vessels, lymph vessels, etc. Furthermore, it offers antioxidant properties and protection to endothelial cells found inside the cardiovascular system organs. Similarly, L-serine drugs help in regulating systolic and diastolic pressure by regulating glucose levels in the body. This efficient maintenance of blood sugar levels also prevents diabetic complications.
However, in the last few years, the most important development in the serine industry is the increased adoption of this amino acid to treat cancer. Journal of Cell Biology, a peer-reviewed scientific journal published by Rockefeller University Press, recently featured a study on the utility of L-serine drugs in oncological therapies. The research paper stated that active serine synthesis improves the amino acid transport capabilities of the body, along with homeostasis, nucleotide synthesis, and folate metabolism. As these body processes get better, the ability of human cells to oxidize nutrients and produce energy also enhances, thus increasing the chances of fighting cancer cells.
Serine-rich products broadening the scope of the cosmetics industry
In the past few years, with the increasing demand for sustainable cosmetics and personal care products, consumer goods companies are transitioning toward the use of eco-friendly raw materials. Many businesses are developing serine-rich products to address the demands of the industry proactively. In February 2024, Kao Corporation, a major chemical manufacturer, announced a new hair care brand viz., Melt. As part of the launch, several hair care products such as serums, shampoos, conditioners, etc., were unveiled. The majority of these items contain amino acids such as arginine, glycine, serine, isoleucine, etc., to facilitate hair growth and improve hair density and volume.
To conclude, the increasing applicability of serine in healthcare and consumer goods industries is predicted to create new investment opportunities in the sector. The widespread use of this amino acid to design therapeutic drugs for diseases such as cancer, Parkinson’s, dementia, Alzheimer’s, etc., has strengthened the footprint of the industry.
