What is the Meaning of Bisphenol A?

Bisphenol A (BPA) is a synthetic organic compound widely employed in the manufacturing of polycarbonate plastics and epoxy resins, which are commonly found in food and beverage containers. It is clinically significant as a prototypical endocrine-disrupting chemical (EDC) because its structure allows it to interfere with the synthesis, secretion, transport, binding, action, or elimination of endogenous hormones. The primary concern is the potential for chronic, low-dose exposure to disrupt the delicate balance of the human endocrine system.

What is the Origin of Bisphenol A?

BPA was first synthesized in 1891, with its large-scale industrial application beginning in the 1950s due to its utility in creating durable plastics. The name is purely chemical, reflecting the two phenol groups in its molecular structure. Its recognition as an EDC is a relatively recent development, arising from toxicology studies that demonstrated its ability to mimic estrogenic activity in biological systems.

What is the Mechanism of Bisphenol A?

As a xenoestrogen, BPA primarily acts by binding to and activating estrogen receptors (ERs), albeit with a lower affinity than natural estradiol. This molecular mimicry disrupts the hypothalamic-pituitary-gonadal axis and other hormone-sensitive pathways by sending inappropriate or untimely signals to target cells. Furthermore, BPA can interfere with thyroid hormone action and non-genomic steroid signaling, leading to widespread endocrine and metabolic dysfunction even at environmentally relevant concentrations.
