δ-Aminolevulinic acid (also dALA, δ-ALA, 5ALA, 5-ALA or 5-aminolevulinic acid), an endogenous non-proteinogenic amino acid, is the first compound in the porphyrin synthesis pathway, the pathway that leads to heme in mammals, as well as chlorophyll in plants.

5-ALA is used in photodynamic detection and surgery of cancer.
