Where does phospholipid synthesis occur?
Smooth ER-->Golgi
Where does TAG synthesis occur?
Cytoplasmic face of ER
1. Either Dihydoxyaceton Phosphate (DHAP) or glycerol converted to?
glycerol 3 phosphate
2. Use what enzyme to put on our FA's to glycerol 3 phosphate? forms what?
acyl transferases

to form phosphatidate or diacyclglycerol-P
3. Diacyclglycerol-P --> TAG
Minus P from diacyclgycerol-P -->1,2 diacylglycerol

Use acyl transferase to make TAG
3. diacylglycerol-P --> Phospholipid
Activate using CTP--> CDP-diacylglycerol
Regulation of TAG & Phospholipid synthesis
Insulin +
"Salvage Pathway"
Use phospholipid breakdown products
Use CTP to activate the alcohol OR diacylglycerol
If cell is trying to make Phosphatidyglycerol or phosphatidylinositol it activates what?
The diacylglycerol componenet
If the cell is trying to make phosphatidylcholine and phosphatidylethanolamine
The headgroup is activated
