phospholipid

 [fos″fo-lip´id]
any lipid that contains phosphorus, including those with a glycerol backbone (phosphoglycerides and plasmalogens) or a backbone of sphingosine or a related substance (sphingomyelins). They are the major lipids in cell membranes.

phos·pho·lip·id

(fos'fō-lip'id),
A lipid containing phosphorus, thus including the lecithins and other phosphatidyl derivatives, sphingomyelin, and plasmalogens; the basic constituents of biomembranes.

phospholipid

(fŏs′fō-lĭp′ĭd)
n.
Any of various phosphorus-containing lipids, such as lecithin and cephalin, that are composed mainly of fatty acids, a phosphate group, and a simple organic molecule. Also called phosphatide.

phospholipid

a compound fat molecule in which there are two FATTY ACIDS and a phosphate group attached to the glycerol, located mostly in cell membranes. Phospholipids in the blood are responsible for the transport and utilization of fats in the body.
