Enzyme kinetics involves the measurement of the rate at which chemical reactions that are catalyzed by enzymes occur. Knowledge about the kinetics of an enzyme can reveal useful information about its ...

At the air-water interface, a negatively charged amino acid carries out a nucleophile attack on a gas molecule to convert it into a product. The reaction rate is enhanced due to significant reduction ...

Thermonuclear reaction rates power the models that explain how stars live, explode and create the elements. A new study ...

Molecular reactant Ball-and-stick model of carbon monoxide. The rate at which the molecule reacts with helium ions can be controlled using microwaves. (Courtesy: Benjah-bmm27) Through new experiments, ...

What are the underlying forces and mechanisms that enable enzymes to accelerate reactions? "Quite recently, we have found that there are enzymes that enhance reaction rates by factors as large as 10 ...
