  <description>LEVULINIC ACID (C5H8O3) is an organic compound with an average molecular weight of 116.12 g/mol. LEVULINIC ACID belongs to the gamma-keto acids and derivatives, a subclass of keto acids and derivatives within the organic compounds. In industrial applications, it is used as a solvent (PMC11639324), a surfactant, a fragrance, a softener and conditioner, and as a nutrient and flavouring (PMC10857383). Additionally, the compound is used in the production of Polyamide plastics.

The compound is found in or released from 34 recorded sources. These include household cleaning and consumer products such as bleaching agents, perfumes within detergents and soaps, cigar cigarettes, non electric simulated smoking devices, and other smoking requisites. It is also associated with food, food processing and cookware, specifically food contact materials, food preservation, the preparation of vinegar, the preparation of wine or sparkling wine, and fermentation processes for beer. Other sources include building and construction materials like ceilings and floors, household items such as coins, and electrical and electronic equipment including amplifiers, antennas, conductors or conductive bodies characterised by the conductive materials, electric switches, and electrically stimulated smoking devices. Recorded exposure routes for this compound include oral, inhalation, and touch. Regarding its biological activity, LEVULINIC ACID is a recorded inhibitor of the protein target Delta-aminolevulinic acid dehydratase (ALAD).</description>
