Introduction
The Michaelis-Menten Equation Calculator is a powerful tool employed in enzymology to explore the kinetics of enzyme-substrate interactions. Named after biochemists Leonor Michaelis and Maud Menten, this equation plays a crucial role in understanding the rate of enzymatic reactions and determining essential parameters for enzyme characterization.
Formula:
The Michaelis-Menten equation is expressed as:
Where:
- is the initial reaction velocity,
- is the maximum reaction velocity,
- is the substrate concentration, and
- is the Michaelis constant representing the substrate concentration at half of .
How to Use?
- Input Substrate Concentration (): Enter the concentration of the substrate used in the enzymatic reaction.
- Specify Maximum Reaction Velocity (): Define the maximum rate of the enzymatic reaction under saturated substrate conditions.
- Set Michaelis Constant (): Input the Michaelis constant, representing the substrate concentration at half of .
- Calculate Initial Reaction Velocity (): The calculator will provide the initial reaction velocity based on the input parameters.
Example:
Let’s consider an enzymatic reaction with a substrate concentration () of 10 mM, a maximum reaction velocity () of 50 units, and a Michaelis constant () of 5 mM. The Michaelis-Menten Equation Calculator will yield the initial reaction velocity ().
