Us animals are capable of amino acid synthesis for some amino acids.
- ars 12y agoNo, it's you that is wrong. You clearly have not read the articles you yourself have linked. > Us animals are capable of amino acid synthesis for some amino acids. Really? You can make an amino acid from ammonia? No, you can not. You can only make amino acids from other amino acids. Here, I'll even link if for you: https://en.wikipedia.org/wiki/Amino_acid_synthesis#From_intermediates_of_the_citric_acid_cycle_and_other_pathways https://en.wikipedia.org/wiki/Amino_acid_synthesis#From_inte... Follow each of the pathways there, and you will see. Each non-essential amino acid is made from another amino aid.
- stefantalpalaru 12y agoDo you realize that you went from animals not being able to synthesize proteins, to not being able to synthesize amino acids to not being able to get nitrogen from sources other than ingested amino acids? Where will you move the post after you find out about niacin?
- ars 12y agoI quote my first message: "Animals can only rearrange existing amino acids into other amino acids or into proteins." Nothing has changed in what I said since then. > Where will you move the post after you find out about niacin? As I replied elsewhere niacin alone is not enough.
