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

Platelet activating factor is an alkylphospholipid

Glycosphingolipids, containing sphingosine and sugar residues as well as fatty acid that are found in the outer leaflet of the plasma membrane with their oligosaccharide chains facing outward, form part of the glycocalyx of the cell surface

After hydrolysis (lipolysis) of triacylglycerol, the utilization of glycerol depends upon whether the tissues have the enzyme glycerol kinase

Triacylglycerol and phosphoglycerols are formed by acylation of triose phosphates

Glycerol 3-phosphate and dihydroxyacetone phosphate are intermediates in glycolysis, making a very important connection between carbohydrate and lipid metabolism.

The regulation of triacylglycerol, phosphatidylcholine, and phosphatidylethanolamine biosynthesis is driven by the availability of free fatty acids.

Fatty acids that escape oxidation are preferentially converted to phospholipids, and when this requirement is satisfied, they are used for triacylglycerol synthesis.

Cardiolipin (diphosphatidylglycerol) is a phospholipid present in mitochondria

Cardiolipin, found in the inner membrane of mitochondria, has a key role in mitochondrial structure and function, and is also thought to be involved in programmed cell death (apoptosis).

Plasmalogens, which comprise much of the phospholipid in mitochondria, are formed by desaturation of the analogous 3-phosphoethanolamine derivative

Platelet-activating factor (PAF) (1-alkyl-2-acetyl-sn-glycerol-3-phosphocholine) is synthesized from the corresponding 3-phosphocholine derivative.

Platelet-activating factor (PAF) is formed by many blood cells and other tissues and aggregates platelets at concentrations as low as 10–11 mol/L. It also has hypotensive and ulcerogenic properties

The biosynthetic pathway of glycerol ether phospholipids is located in peroxisomes.

The CDP-choline is required in the synthesis of PAF

The CDP-ethanolamine is required in the synthesis of plasmalogens

Acetyl-CoA is required in the synthesis of PAF

Phospholipase A2 is required in the synthesis of PAF

Acetyltransferase is required in the synthesis of PAF
