1)   TAGs are broken down into glycerol and fatty acids, what happens to them?

2)    Fats feed glucogenesis in a very efficient way, what is this way?

3)    What are the primary differences between glycolysis and gluconeogenesis?

Solutions

Expert Solution

1. TAG = Triacylglycerol
It contains three fatty acids attached to a glycerol molecule.
Hydrolysis of a TAG produces fatty acids and glycerol.
Fatty acids are broken down in the beta-oxidation pathway to produce Acetyl CoA.
Glycerol is converted to Glycerol-3-phosphate and then to DHAP. DHAP enters glycolysis.

High-fat foods are known to cause hepatic-insulin resistance.
They promote gluconeogenesis.
