5-Aminolevulinic Acid Hydrochloride Salt (5-ALA HCl) is a naturally occurring amino acid and a precursor of tetrapyrroles in the biosynthesis of chlorophyll and heme. It is considered an antineoplastic photosensitizer. 5-Aminolevulinic Acid Hydrochloride Salt converts to protoporphyrins within tissue upon exposure to light, which produces byproducts in the form of reactive oxygen species. It is known to have anti-inflammatory, antioxidant, and anti-tumor activities. Researchers study the effects of 5-Aminolevulinic Acid Hydrochloride Salt on various biological processes, such as inflammation, cell proliferation, and gene expression.
