After making the three molecules of fatty acids with
CoA from fatty acids synthesis. They're called (Fatty s
Acyl CoA), they must be linked into a chain called
glycerol. This metabolism mainly occurs in the liver. I FA CoA's

How can we get the glycerol chain? con

1. From lipolysis of Fats to glycerol and then convert it
into Glycerol-3-Phosphate by Glycerol kinase enzyme. E

2. Or converting DHAP that comes from Glycolysis into
Glycerol-3-Phosphate.

Now the process of combining the Glycerol-3P with three
molecules of Fatty Acyl CoA's.

Firstly, the FA CoAs are added in a sequence. Beginning
with the first FA CoA combines with the first carbon at
the Glycerol chain. It's catalyzed by (the Acyl

Transferase enzyme). And popping off the CoA. The new
molecule is called (Lysophosphatidic Acid) (MAG)

Secondly, the 2nd FA CoA has to be unsaturated. And
then binds with the 2nd carbon on the chain catalyzed

by the same enzyme. The molecule is called (Phosphatidic I poi d In Acyltransferas

Lastly, before adding the last FA CoA, we first have to
get rid of the phosphate group on the 3rd carbon by a
