## constant

The annual payment required to pay the principal and interest due on a \$1 loan for a specified repayment term at a specified interest rate.Before the widespread availability of computers and extremely affordable financial calculators,it was common to use mortgage constant tables to calculate monthly payments. One would refer to the table for the proper loan term, such as 30 years, and then within that table find the loan constant for the anticipated interest rate. See the following example. The constant is the monthly payment on \$1. To find out your own monthly payment, you multiply the constant by the number of dollars in your loan, and the answer is what your monthly payments would be.

Michaelis constant [K.sub.m] indicates substrate concentration in which reaction rate is half of maximum velocity.
When an enzymatic reaction follows Michaelis-Menten kinetics, the equation for the initial velocity of reaction as a function of the substrate concentration is characterized by two parameters, the Michaelis constant, [K.sub.m], and the maximum velocity of reaction, [V.sub.max].
The Michaelis constant ([K.sub.m]) and maximum rate of reaction ([V.sub.max]) of free and immobilized lipase were calculated from Lineweaver-Burk (LB), Hanes-Woolf (HW), Scatchard (Scat) and Eadie-Hofstee (EH) plots.
For determining Michaelis constant ([K.sub.m]) and maximum velocity ([V.sub.max]) values of the enzyme, PPO activities were measured with catechol at varying concentrations under optimum conditions of pH and temperature.
where [K.sub.M,2] is Michaelis constant for a second substrate and [S.sub.20] is initial concentration of a second substrate,
