  <description>Piperacillin is a compound with the chemical formula C23H27N5O7S. Piperacillin belongs to the amino acids, peptides, and analogues, a subclass of carboxylic acids and derivatives within the organic compounds. With an average molecular weight of 517.55 g/mol, Piperacillin is a heavy molecule.

The compound is found in or released from 11 recorded sources. These include healthcare, pharmaceuticals &amp; veterinary products such as antibiotics and penicillins, and food, food processing &amp; cookware, specifically processing meats. It is also associated with household cleaning &amp; consumer products, including tobacco pipes, cigar cigarettes, other smoking requisites, and non electric simulated smoking devices. Additionally, it is linked to electrical &amp; electronic equipment, such as video games, television systems, electrically stimulated smoking devices, and electric hearing aids. Recorded exposure routes for the compound include oral, intravenous, intramuscular, inhalation, and parenteral administration.

In terms of biological activity, Piperacillin interacts with four recorded protein targets. It acts as an inhibitor of serine-type D-Ala-D-Ala carboxypeptidase (pbp3) and targets penicillin-binding protein 1b (pbp1b), penicillin-binding protein 2a (pbp2a), and penicillin-binding protein 2B (penA).</description>
