Phosphoryl group from 1 ATP molecule is attached to C3 of a glycerol molecule, (Enzyme: Glycerol Kinase)
8 of 14
Describe how you make G3P from dihydroxyacetone
DHAP is reduced to form G3P, hydrogen donor NADH+H, (Enzyme: Glycerol-3-phosphate dehydrogenase), reversible, DHAP from glycolysis
9 of 14
Once G3P is synthesised, what happens?
Fatty acids must be converted to the corresponding acyl CoAs, energy requiring process- 2 ATP per fatty acid, (Enzyme: Fatty acyl CoA synthase)
10 of 14
What is the first step of the second stage? (after the fatty acids have been converted)
The fatty acyl group of the first fatty acyl CoA is esterified at the -OH from C1 of the G3P, (Enzyme: Glycerol-3-phosphate acyltransferase), product: Lysophosphatidic acid
11 of 14
What is the second step?
The 2nd fatty acyl CoA is esterified at the _OH of C2 of the lysophosphatidic acid, (Enzyme: Glycerol-3-phosphate acyltransferase), product: Phosphatidic acid (A glycerophospholipid)
12 of 14
What is the third step?
The phosphate group from the C3 is removed (Enzyme: phosphatidate phosphatase), product: Diacylglycerol
13 of 14
What is the final step?
A final fatty acyl CoA is esterified on C3 of DAG, (Enzyme: acyltransferase), product: Triacylglycerol
