Although many organisms capture and respond to sunlight, enzymes – proteins that catalyze biochemical reactions – are rarely driven by light. A new study captures the full cycle of complex structural changes in an light-driven enzyme called FAP as it transforms a fatty acid into alkanes or alkenes.
Derived from crude oil, toxic to synthesize, and slow to degrade, polyurethanes are not environmentally friendly. Today, researchers discuss a safer, biodegradable alternative derived from fish waste that would otherwise likely be discarded. They will present their results at ACS Spring 2021.
