Fatty acid synthesis

Fatty foods include red meat, dairy products, and even peanut butter.
This occurs by combining lots of 2-carbon molecules, called acetyl-coenzyme A or acetyl-CoA, into a single 16-carbon, long chain fatty acid called palmitoyl-coenzyme A, or palmitoyl-CoA.
Palmitoyl-CoA can then serve as a precursor to even longer chain fatty acids.
To make palmitoyl-CoA, acetyl-CoA provides the carbon atoms, and nicotinamide adenine dinucleotide phosphate, or NADPH provides the hydrogen atoms.
As it turns out, most of the acetyl-CoA used to make fatty acids comes from carbohydrate metabolism - specifically glucose, which is a 6-carbon sugar molecule.
After eating a glucose-rich dinner, like cake and cookies, glucose levels in the blood rise quickly.
Fatty acids are one of the essential forms of energy storage. The biosynthesis of fatty acids is a multi-step process in the cytoplasm, mainly of the liver and fat cells. The process takes place in three major steps: the citrate shuttle, acetyl-CoA carboxylase (the rate-limiting step), and fatty acid synthase complex.
