Type II pneumonocytes isolated from adult rats incorporate radioactivity from 1-[3H]hexadecanol into either lipids. The radioactivity is distributed between the neutral lipids, phosphatidylcholines, and phosphatidylethanolamines. The neutral lipid fraction is almost exclusively composed of triradylglycerols. The potent ether-containing glycerophospholipid, platelet-activating factor, has been shown to stimulate glycogen breakdown and surfactant secretion. In consideration that a long chain alcohol (hexadecanol) is added to certain artificial surfactant preparations which are utilized in the treatment of respiratory distress syndrome of the newborn, the metabolism of hexadecanol by the type II pneumonocytes should be taken into account.

D010742 Phospholipid Ethers Phospholipids which have an alcohol moiety in ethereal linkage with a saturated or unsaturated aliphatic alcohol. They are usually derivatives of phosphoglycerols or phosphatidates. The other two alcohol groups of the glycerol backbone are usually in ester linkage. These compounds are widely distributed in animal tissues.
