How exactly would you make an amino acid from glucose or a fatty acid? There is no nitrogen in either of those.
All those amino acids are made from OTHER amino acids.

With this: http://en.wikipedia.org/wiki/Citric_acid_cycle
The Critic acid cycle is awesome, but it can not perform nuclear synthesis. It has no way to making nitrogen.
As I've said 3 times already, it makes amino acids from other amino acids.
One of the ingredients is NAD, which is made from tryptophan or aspartic acid, both of which are amino acids.
You are simply wrong, and you need to update your information.
Animals can only make amino acids from other amino acids.
Or niacin: http://en.wikipedia.org/wiki/Niacin
NAD is made of nicotinamide AND Adenine. Adenine is in turn made from the amino acids glycine, glutamine, and aspartic acid.
Are you going to acknowledge you were wrong, and actually learn something? Or will you keep arguing?
