Amino acids form the essential building blocks of peptides and proteins, with the standard genetic code utilizing only twenty L-forms, collectively known as the canonical set. In contrast, D-amino acids are their mirror-image stereoisomers and are therefore classified as non-canonical amino acids (ncAAs). Unlike L-amino acids, they are not directly incorporated into ribosomally synthesized proteins. However, D-amino acids are found naturally in bacterial cell walls, certain peptide antibiotics, and fermented foods. Their unique stereochemistry imparts distinct physical and biological properties, which have made them increasingly valuable in pharmaceuticals, food science, materials research, and biotechnology.
