BPA has been found to interact with a diverse range of hormone receptors, in both humans and animals. It binds to both of the nuclear estrogen receptors (ERs), ERα and ERβ. BPA can both mimic the action of estrogen and antagonise estrogen, indicating that it is a selective estrogen receptor modulator (SERM) or partial … See more Bisphenol A (BPA) is a chemical compound primarily used in the manufacturing of various plastics. It is a colourless solid which is soluble in most common organic solvents, but has very poor solubility in … See more BPA has a fairly high melting point but can be easily dissolved in a broad range of organic solvents including toluene, ethanol and See more Concerns about the health effects of BPA have led some manufacturers replacing it with other bisphenols, such as bisphenol S and bisphenol F. These are produced in a similar manner to BPA, by replacing acetone with other ketones, which undergo analogous … See more Bisphenol A was first reported in 1891 by the Russian chemist Aleksandr Dianin. In 1934, workers at I.G. Farbenindustrie reported the coupling of BPA and epichlorohydrin. Over the following decade, coatings and resins derived from similar materials … See more The synthesis of BPA still follows Dianin's general method, with the fundamentals changing little in 130 years. The condensation of acetone (hence the suffix 'A' in the name) with two equivalents of phenol is catalyzed by a strong acid, such as concentrated See more Major uses Polycarbonates About 65–70% of all bisphenol A is used to make polycarbonate plastics, which can consists of nearly 90% BPA by mass. Polymerisation is achieved by a reaction with See more Exposure As a result of the presence of BPA in plastics and other commonplace materials, most people are frequently exposed to trace levels of BPA. … See more WebIn this work, we report the chemical synthesis and purification of BPA mono- and di-glucuronide and BPA mono- and di-sulfate. Their levels, as well as that of BPA, in 140 …
