A deep and analytical understanding of the enzyme kinetics has attracted a great attention of scientists from biology, medicine, chemistry, and pharmacy. Mathematical models of enzyme kinetics offer several advances for this deep and analytical understanding due to their in compensable potential in predicting kinetic processes and anticipating appropriate interventions when required. This chapter concerns mathematical modeling analysis and simulation of enzyme kinetics. Experimental data and available knowledge on enzyme mechanics are used in constituting a mathematical model. The models are either in the form of linear or nonlinear ordinary differential equations or partial differential equations.

Computer Modeling of Chemical Reactions in Enzymes and Solutions
Enzyme catalysis is the increase in the rate of a process by a biological molecule , an " enzyme ". Most enzymes are proteins, and most such processes are chemical reactions. Within the enzyme, generally catalysis occurs at a localized site, called the active site. Most enzymes are made predominantly of proteins, either a single protein chain or many such chains in a multi-subunit complex.
Combining hydrogen and oxygen to make water is a physical change. The three basic properties of matter are volume, mass, and shape. H 20 molecules are cohesive; they form hydrogen bonds with each other.

E-mail: warshel usc. Enzymes perform key life professes at time ranges needed for synchronisation between the relevant reaction cycles. This sometimes requires enormous rate acceleration, whose origin presents a major puzzle both on a fundamental and practical level. Several proposals have been put forward to try to rationalise the catalytic power of enzymes but, in our view, resolving the merit of the different options cannot be accomplished without the use of computer simulations. To provide the reader with a perspective of the crucial direction of modelling of enzymatic reactions we consider the advances in the field both in the technical and fundamental directions.
