Main Question or Discussion Point
If one had no way of eating any protein, but could eat carbohydrates and something which had nitrogen that wasn't a protein, could their body assemble proteins to use, or does that mechanism not exist?
I know this. I said that some amino acids contain sulfur. That is Methionine and Cysteine. Eating only hydrocarbons and nitrogen wouldn't get you those :)Monique said:Aychamo: amino acids have a NH3+ group, thus you need a nitrogen source (like wasteofo2 mentioned).
