Lecithin is a mixture of fats essential for cells in the human body. Many foods contain lecithin, including soybeans and egg yolks. Composed of fatty acids, lecithin has a variety of commercial and medicinal uses. Lecithin works as an emulsifier, meaning it suspends fats and oils and prevents them from mixing with other substances.
Lecithin supplements are used to help treat high cholesterol and aid breastfeeding. In the diet, lecithin is the main source of choline, a nutrient similar to the B vitamins. Lecithin is converted to acetylcholine, a substance that transmits nerve impulses. It uses lecithin for the treatment of Alzheimer's disease and dementia, Parkinson's disease and similar conditions, but there is no good scientific evidence to support these uses.
Lecithin supplements are usually derived from sunflower seeds, eggs or soybeans. Soy is the most commonly used ingredient to create lecithin supplements. Animal fats, fish and corn are also sometimes used for this purpose.
Soybean lecithin is more likely to come in the form of granular capsules. Sunflower lecithin is available in both powder and liquid form. Sunflower lecithin is not that common, but people who are trying to avoid genetically modified organisms (GMOs) especially in their diet prefer it. But soybeans are genetically modified, sometimes in mass production, while sunflower seeds are not. Also, no harsh chemicals are used to extract lecithin from sunflower seeds.
High performance liquid chromatography (HPLC) method is generally used in the analyzes applied in advanced laboratories for the determination of lecithin. This method is an important analytical method widely used to separate and quantify the components of liquid samples. In this method, a solution (mobile phase) is pumped through a column (stationary phase) of small porous particles attached to the surface. The different solubilities of the sample components in the two phases cause the components to move at different speeds along the column and these components separate. There are several modes of liquid chromatography depending on the type of mobile and stationary phase used.
