Phosphatidylserine (pronounced fos-fa-ti-dil-se-reen) is a type of fat that is a major component of the cell membrane. It is also known as PS and is particularly concentrated in the brain.
Etymology
The term "Phosphatidylserine" is derived from the Greek words "phosphatidyl", meaning "phosphate", and "serine", an amino acid.
