This video was created for Jeff Saven's course CHEM 251: Principles of Biological Chemistry. Professor Saven tasked us to create a 5 minute video discussing the molecular basis of a biological process. My group focused on the compound BPA (bisphenol A), which has been quite controversial in public discussion. BPA is widely used in daily plastic products, despite some research pointing the compound's disruptive nature to fundamental human hormonal processes. We focused on the effects of BPA on steroidogenesis, a pathway producing hormones such as testosterone and estrogen.
