Description
Amoxicillin is an organic compound with the chemical formula C16H19N3O5S and an average molecular weight of 365.40 g/mol. Amoxicillin belongs to the beta lactams, a subclass of lactams within the organic compounds. It is further classified within the superclass of organoheterocyclic compounds. In terms of biological activity, amoxicillin acts as an inhibitor of the protein target penicillin binding protein (PBP1). The compound has been identified in or released from 24 recorded sources. These include healthcare, pharmaceuticals, and veterinary products, specifically antibiotics, penicillins, and drugs for acid related disorders. It is found in aquatic systems and sediments, such as seawater, freshwater, surface water, and groundwater, as well as drinking water and water supply sources including tap water, bottled water, and desalinated water. Additionally, it is present in wastewater, sanitation, and biosolids, including wastewater treatment effluent, industrial wastewater, mine wastewater, and unspecified wastewater. Other recorded sources include marine, shipping, and aquaculture environments, specifically bilge water and ballast water, as well as appliances, HVAC, and refrigerants, such as water heaters and water coolers, along with four more sectors. Recorded exposure routes for amoxicillin include oral, intravenous, inhalation, and touch.
