ABSTRACT
Most organisms’ metabolism depends on the 20 DNA-coded protein amino acids. There are approximately 1,000 molecules in nature that have the same basic structure. Many amino acids are plant-related metabolites. Non-protein amino acids, which can be found in legumes, fruits, seeds, and nuts, are common in human diets worldwide. They have a clear risk of harming human health if they get into the food supply. Amino acids that aren’t proteins can have a variety of negative consequences. In this chapter, toxic amino acids will be introduced with a particular focus on chemistry, classification, mechanism of action, toxicology, identification and quantification, safety, precautions, regulation, and their future scope.
