Introduction: The incidence of asthma exacerbations in patients receiving salmeterol/fluticasone propionate (Seretide™ or Advair ®) is low. However, when asthma control deteriorates ...

Enzyme mechanisms are the chemical transformations, and the steps within them, generated by enzymatic action on substrates. The mechanism of enzyme catalysis is similar in principle to other types ...

A reaction mechanism is a sequence of elementary reactions that can explain how an overall chemical reaction proceeds. The ozonolysis of α-pinene is important in atmospheric secondary organic ...
