Only 9 of the 22 "standard" amino acids can't be synthesized de novo by the human body.
- ars 12y agoThat is simply untrue. 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.

- ars 12y agoDid you even read your own link? 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.

- ars 12y agoYou keep linking to pages that refute your own point. 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?
- aurelian 12y agoIncorrect. Please read page 2 carefully. http://www.tamu.edu/faculty/bmiles/lectures/biosynaa.pdf http://www.tamu.edu/faculty/bmiles/lectures/biosynaa.pdf
