Abbreviated to PS and also known as phosphatidyl serine, phosphatidylserine is a compound used by the body for normal cellular structure and function.
Phosphatidylserine is endogenous; this compound is produced in the body.
However, phosphatidylserine can also be obtained from the diet as discussed in the section, sources of phosphatidylserine, below.
Within the body, absorption of phosphatidylserine occurs within the small intestine.
As a dietary supplement, phosphatidylserine brings many benefits.
The structural formula of phosphatidylserine is: C13H24NO10P
Phosphatidylserine is classed as a phospholipid. A phospholipid is a compound which has both a phosphate group and a lipid component.
Lipids are naturally occurring compounds. Lipids are fats, or fat like substances. Examples of these oily substances include waxes, fats and oils. A key characteristic of lipids is that they are soluble in organic solvents but insoluble in water.
The Body - phosphatidylserine can be produced in the body. Within the body, higher concentrations of phosphatidylserine are found within the internal organs.
The brain, liver and kidney have relatively high concentrations of phosphatidylserine.
Food Sources of Phosphatidylserine - phosphatidylserine can also be obtained externally from dietary sources.
Oily fish such as mackerel and tuna are rich sources of phosphatidylserine; more limited concentrations of phosphatidylserine can be found in dairy products, rice and root vegetables.
