PhosphatidylSerine

PhosphatidylSerine is a major structural component of neural membranes. Phosphatidylserine is a natural nutrient found as part of the cell membrane of cells. Phosphatidylserine is most notably found in the cell membrane of neurons, comprising about 7 to 10 percent of its lipid content. Phosphatidylserine consists of serine attached to fatty acids. The serine molecule in phosphatidylserine found in cow brain is attached mostly to long chained polyunsaturated fatty acids such as DHA or AA (arachidonic acid). In addition, the cow brain extract is not pure phosphatidylserine. Phosphatidylserine is a phospholipid which has been claimed to enhance neuronal membrane function, and can be derived from several sources.
