A Review of Nervonic Acid Production in Plants

Nervonic acid is a fascinating fatty acid found in various plant-based oils, yet its production in plants is not as widely discussed. Let’s explore how plants produce this crucial nutrient.

Nervonic acid is a monounsaturated fatty acid found in several plant oils, particularly in rapeseed, flaxseed, and mustard oil. It’s vital for myelin formation and brain health.

Understanding how nervonic acid is produced in plants is essential, as it can provide insights into how we can optimize its extraction for human health and supplements. Let’s break it down.

How Is Nervonic Acid Produced in Plants?

Nervonic acid production in plants occurs through the biosynthesis of fatty acids, specifically through elongation pathways¹. These pathways convert shorter fatty acids into longer chains like nervonic acid, which contains 24 carbon atoms.

Nervonic acid is synthesized in plants by elongating fatty acids, particularly by modifying oleic acid into the 24-carbon structure.

In plants, this fatty acid is most commonly found in the oils of seeds, especially those of rapeseed, flaxseed, and mustard. These plants produce nervonic acid as a way to store energy and maintain cellular structure, particularly in the membranes of seeds.

What Plants Are Known for High Nervonic Acid Content?

Among the many plants that can produce nervonic acid, some are particularly noted for their high concentrations. Rapeseed oil is the most significant commercial source, known for containing up to 40% of the fatty acid.

Rapeseed oil, flaxseed oil, and mustard oil are the primary plant-based sources of high nervonic acid levels.

Plants synthesize long-chain fatty acids like nervonic acid through an elongation process. It starts with shorter fatty acids like palmitic acid and stearic acid, which are then extended by adding carbon atoms. The key enzyme in this process is called elongase², which helps catalyze the addition of two-carbon units to the fatty acid chain. In plants like rapeseed, this process results in nervonic acid, which is incorporated into the oil in seeds, contributing to the seed’s energy storage and integrity.

By elongating fatty acids, plants can produce longer-chain acids like nervonic acid, which plays a crucial role in the structure and function of plant cells.

Why Is Nervonic Acid Important for Plant Function?

In plants, nervonic acid serves several vital roles. Like in humans, it helps maintain cell membrane integrity, particularly in seed cells. The fatty acid also serves as an energy reservoir during germination and early plant growth, ensuring that the plant has enough energy to sustain itself until it can start photosynthesizing.

Nervonic acid in plants supports cellular function and provides energy during germination, ensuring healthy growth.

During seed germination, the stored lipids in the seed are broken down and used to fuel the growth of the plant. Nervonic acid, as part of the plant’s lipid profile, plays a role in stabilizing the cell membranes, ensuring that the cells can divide and grow effectively. The presence of nervonic acid in seed oils enhances the seed’s ability to remain viable under challenging conditions, improving overall germination rates.

Nervonic acid enhances seed viability by stabilizing membranes, improving the seed’s ability to withstand harsh conditions and thrive.

What Are the Methods of Extracting Nervonic Acid from Plants?

To make use of nervonic acid for supplements or other applications, it needs to be extracted from plant oils. The extraction process usually involves pressing or solvent extraction to obtain the oil, followed by further purification to isolate the nervonic acid.

Nervonic acid is extracted through oil pressing or solvent extraction, followed by purification to ensure high-quality, concentrated fatty acid.

There are several extraction methods for obtaining nervonic acid from plant oils. Cold pressing is the most natural and eco-friendly approach, although it may yield smaller amounts. Solvent extraction, on the other hand, is more efficient and can extract higher concentrations of nervonic acid but may involve the use of chemical solvents that require careful removal. After extraction, further purification methods, such as chromatography or distillation, are used to isolate nervonic acid from other fatty acids present in the oil.

Solvent extraction and cold pressing are the most common methods used for obtaining nervonic acid, each with its own advantages and limitations.

Choosing the right extraction method depends on the desired yield, purity, and cost-effectiveness.

How Can We Optimize Nervonic Acid Production?

While nervonic acid is naturally produced in plants, the levels can vary depending on the plant species, environmental conditions, and cultivation practices. Optimizing nervonic acid production involves selecting the right plant variety, improving growing conditions, and using biotechnological advancements³ to enhance fatty acid synthesis.

Optimizing nervonic acid production can be achieved by improving plant cultivation practices and using biotechnological tools to increase fatty acid synthesis.

Recent advancements in plant biotechnology have made it possible to enhance the production of nervonic acid. By genetically modifying plants to express higher levels of elongase enzymes, scientists can increase the synthesis of nervonic acid. This biotechnological approach could lead to higher yields of nervonic acid, making it more accessible for use in supplements and other health products.

Biotechnological advancements can enhance nervonic acid production by optimizing the genetic pathways involved in its synthesis.

Conclusion

Nervonic acid is a key component in both plant health and human wellness, especially in cognitive function. Through improved plant cultivation and biotechnological innovations, we can increase the availability of this vital fatty acid. Whether you’re a producer or consumer, understanding its production in plants is crucial for tapping into its benefits.
