An alternative pathway in liver enables phosphatidylethanolamine to give rise directly to ----------- by progressive methylation of the ethanolamine residue.

---------------- catalyzes the only step specific for triacylglycerol synthesis and is thought to be rate limiting in most circumstances

Cardiolipin (diphosphatidylglycerol) is a phospholipid present in mitochondria. It is formed from phosphatidylglycerol, which in turn is synthesized from CDP-diacylglycerol and ------------------

Cardiolipin, found in the ----------------------------

Plasmalogens and platelet activating factor are

----------------- is the precursor of the glycerol moiety in the synthesis of glycerol ether phospholipids

------------------ is the precursor of the glycerol moiety in the synthesis of plasmalogens

The ----------------- is the precursor of the glycerol moiety in the synthesis of platelet activating factor

Phospholipase A2 catalyzes the hydrolysis of glycerophospholipids to form a--------and lysophospholipid

Lysophospholipid (eg, lysolecithin) is attacked by lysophospholipase, forming the corresponding glyceryl phosphoryl base, which may then be split by a hydrolase liberating ------------------ plus base.

Long-chain saturated fatty acids are found predominantly in the 1 position of phospholipids

All sphingolipids are formed from

- In the synthesis of ceramide, the ---------------- is required as a reductant in the 3-ketosphinganine reductase step

In the synthesis of ceramide the following are required

When ceramide reacts with phosphatidylcholine the products are -----------------plus diacylglycerol

---------------- are synthesized from ceramide by the stepwise addition of activated sugars (eg, UDPGlc and UDPGal) and a sialic acid, usually N-acetylneuraminic acid.

------------------- are the major energy-storing lipids

All the following are amphipathic except

Triacylglycerols and some phosphoglycerols are synthesized by progressive acylation of -------------------

Dipalmitoyl lecithin is a major component of lung surfactant, which is lacking in respiratory distress syndrome of the newborn.

Inositol phospholipids in the cell membrane act as precursors of hormone second messengers
