Non-protein amino acids

Non-protein amino acids refer to those amino acids that do not appear as standard protein components. They are divided into natural non-protein amino acids and artificially synthesized non-protein amino acids. These amino acids usually do not participate in the formation of protein polypeptide chains, but they may play a key role in the metabolic process or exist as biologically active molecules. Non-protein amino acids are widely present in nature and play an important regulatory role in the metabolic process of organisms. With the advancement of science and technology, the research and application of non-protein amino acids will continue to expand, especially in the fields of drug development, food additives and synthetic biology.
