Plasmalogens are a distinct class of glycerophospholipids involved in many of the body’s cellular functions.
These molecules are among the building blocks of cell membranes. Like the walls of an apartment, membranes create barriers that separate and compartmentalize the different components and organelles within a cell.
Most glycerophospholipids can be obtained from food, but plasmalogens are an exception. The body makes them primarily in peroxisomes, specialized organelles found in nearly every cell. Plasmalogens are also less stable outside the body and tend to break down in the acidic environment of the stomach. Their unique structure and function are why they matter so much to cellular health and to the regulation of many biological processes.
Plasmalogens are especially important in the brain and nervous system. RCDP is characterized by an inability to produce them, which affects myelination and brain development. Research into plasmalogen biochemistry has focused on understanding this deficiency and how it shapes the condition.
