Exponential model for a regulatory enzyme. Computer program for the determination of the model constants from initial velocity data

open access: closedInternational Journal of Bio-Medical Computing, 1987
The paper describes a program (DESCENT) which evaluates the constants of the exponential model for a regulatory enzyme with up to four substrates or up to three substrates and one effector. The program operates by repetitive adjustment of the model constants so as to secure a better fit between the observed and calculated initial velocities of reaction.

A computer program for calculating antibody affinity constants

Computer Methods and Programs in Biomedicine, 1988
A program is presented for the calculation of antibody affinity constants which avoids the limitations of graphical plotting of titration data using the Sips or Scatchard equations.

Program PKAS: a novel algorithm for the computation of successive protonation constants [PDF]

open access: possibleCanadian Journal of Chemistry, 1982
A new algorithm for the simultaneous determination of any number of protonation constants from potentiometric equilibrium data is described. This algorithm is characterized by a unique approach to the internal refinement of the constants and by the analytical nature of the numerical analysis whereby minimization is sought and achieved on the residuals

A desk computer program for the calculation of rate constants

Reaction Kinetics and Catalysis Letters, 1984
A desk computer program has been written in BASIC programming language to optimize the values of rate constants determined from kinetic measurements of time and concentration data. The program is capable of the simultaneous refinement of a maximum of 5 rate constants. A FORTRAN version using the Gear method is also available.

Computer program of calculation method for a constant-environment calorimeter

Thermochimica Acta, 1987
Abstract A computer program (in BASIC) for the determination of heats of solution and reaction in a constant-environment calorimeter has been developed. Particular attention was paid to the choice of parameters such as K / C and the endpoint of a generic calorimetric reaction in solution.

A critical comparison of computer programs for the potentiometric determination of stability constants

Analytica Chimica Acta, 1986
Abstract The performance of five of the best-known computer programs LETAGROP, SCOGS, MINIQUAD, SUPERQUAD and ESTA, is critically discussed. All these programs are based on least-squares refinement procedures but differ in some important aspects: (a) the definition of the residuals function; (b) the minimization procedure; (c) the statistical and ...
