Larger Intrinsic Rate Constants of Alpha-amylase is Possible if Intrinsic Forward Rate Constant is ≠ Diffusion limited Rate of Encounter

Ikechukwu I. Udema · Asian Journal of Chemical Sciences · 2022

Background: Previous research has shown that the intrinsic reverse (backward) and forward rate constants are larger than the effective or apparent rate constants for the formation and dissociation of an enzyme-substrate complex (ES). It is speculated that such intrinsic rate cons...

Non-equilibrium Binding Energy Determined Using Alpha-amylase Catalysed Amylolysis of Gelatinised Starch as a Probable Generalisable Model and Importance

Ikechukwu I. Udema · Asian Journal of Chemical Sciences · 2020

Objectives: This research was undertaken to determine the non–equilibrium binding energy by calculation after substituting experimental data into derived equations, present its role distinct from energy associated with activated enzyme–substrate (ES) complex and ultimately elucid...

A Novel Mathematical Equation for a Noninvasive Determination of the Number of Alveoli of the Human Lung

Ikechukwu I. Udema · Asian Journal of Biology · 2020

Background: There had always been a spirited effort in understanding the transport of air or molecular oxygen plus other gases from alveolar air space into the pulmonary capillaries and from the latter back into the former using mathematical models; the determination of the numbe...

A Two-part Approach to the Determination of Intrinsic Rate Constants of an Alpha-amylase Catalysed Reaction

Ikechukwu I. Udema · Asian Journal of Chemical Sciences · 2020

Background: There is a need for equations with which to calculate the intrinsic rate constants that can further characterise enzyme catalysed reactions despite what seems to be conventional differences in methodology in the literature. Methods: Theoretical, experimental (Bernfeld...

The Key to Effective Catalytic Action is Pre-catalytic Site Activity Preceding Enzyme-substrate Complex Formation

Ikechukwu I. Udema · Advances in Research · 2017

Aims: i) To show that attractive electrostatic interaction is essential to stable enzyme-substrate formation, ii) to determine the minimum interparticle distance for maximum attractive interaction, iii) to determine the duration and the velocity of transit before enzyme substrate...

Temperature Induced Conformational Entropy of α-Amylase with and without Additive

Ikechukwu I. Udema · International Journal of Biochemistry Research & Review · 2017

Aims: 1) To formulate models based on defined principle for the application of Fitter’s model and 2) ultimately show that there are changes in the radius of an enzyme in solution and consequently conformational entropy change with temperature before and during catalytic activity....

Determination of Molar Mass and Its Relationship with Free Energy of Activation: A Case Study on Human Salivary Alpha Amylase

Ikechukwu I. Udema · Journal of Scientific Research and Reports · 2016

Aims: The objectives of the research were (i) to show that the mass concentration, molar mass of one-active site enzyme, and consequently, the type of human salivary alpha amylase (HSαA), can be determined using kinetic parameter dependent model, (ii) to show that the free energy...
