Labster enzyme kinetics.

Enzymes are biological catalysts, and like all catalysts, their properties are studied by measuring their rates of reaction or kinetics.

The Michaelis-Menten equation assumes a simple reaction of the form: E+ S − ⇀ ↽ − ES E + P. where E is an enzyme, S is the substrate, and P is the product. Note the formation of the intermediate enzyme-substrate complex, ES, which is a transition state (recall Figure 3.3.2) in which the substrate is unstable and associated with the enzyme.Abstract.

Abstract. Enzyme kinetics is arguably the most time and cost effective way to study enzymes. It is the primary way to study enzyme catalysis, because no other approach allows one to test whether a chemically or spectrophotometrically detected intermediate is formed and turned over on the catalytic timescale.V m a x is the Y-value (initial rate of reaction value) at which the graph above plateaus. The substrate concentration that gives you a rate that is halfway to V m a x is called the K m , and is a useful measure of how quickly reaction rate increases with substrate concentration. K m is also a measure of an enzyme's affinity for (tendency to ...Now in full color for a more intuitive learning experience, this new edition of the long-selling reference also features a number of new developments in methodology and the application of enzyme kinetics.
