Plasmalogens are a unique class of glycerophospholipids with a vinyl - ether bond at the sn - 1 position of the glycerol backbone. They are widely distributed in mammalian tissues, especially abundant in the brain, heart, and immune cells.
Plasmalogens are considered important bioactive lipids. Dietary intake of foods rich in plasmalogens or supplementation may have beneficial effects on human health, including cognitive function improvement and cardiovascular protection.
