Amino acids each have an amine and a carboxylic acid functionality. When they're hooked together in a polypeptide (protein), the peptide from is an amide bond. They also each have a unique sidechain. A couple of these (glutamine and asparagine) have amides on this group.

yep..amino acids at physiological pH have an amine group as well as a carboxilic group. the fav amino acid on this board is obviously tryptophan, the brightest glowing a.a. under UV "Nothing is true, everything is permitted." ~ hassan i sabbah

that's nice
i'm guessing the reason diethylamine and triethylamine isn't found in plants is it's toxic nature of forming, it has something to do with ammonia and alcohol mixing right? ammonia is only in the air or water in trace amounts in nature, right? + alcohol is only formed when something ferments. Otherwise, only acetic acid is actually used by plants, not alcohols, right?

well not necessarily.. plants also have the ability to oxidize primary alcohols to aldehydes. and the atmosphere was theoretically mostly ammonia at one time. plants don't produce diethylamine because an amino acid metabolic pathway required for its production is lacking "Nothing is true, everything is permitted." ~ hassan i sabbah

there's no specific reason? no plant has ever been found that produces diethylamide, right? must have been evolutionarily non reasonable
