Phosphatidylcholine is a glycerophospholipid that is involved in the metabolism
of several lipid compounds. It is synthesized in the reaction
below (see Figure 19.5):
Phosphatidylcholine is a glycerophospholipid that is involved in the metabolism
of several lipid compounds. It is synthesized in the reaction
below (see Figure 19.5):
CDP--Choline + Diacylglycerol <=> CMP + Phosphatidylcholine (catalyzed by CDP-choline: 1,2-Diacylglycerol Phosphocholine Transferase)
Phosphatidylcholine can also be synthesized in the reaction shown here.
The sphingolipid, sphingomyelin, is made by transferring choline from phosphatidylcholine to a ceramide (Figure 19.13).
