Introduction to Enzymology

Enzymology is a field of study that deals with a specific group of proteins called enzymes. These proteins accelerate specific chemical reactions in a biological system, and these reactions are essential to the growth, development, adaptation, and survival of the organism. The absence, accumulation, or dysfunctionality of an enzyme has…

The Nuclear Overhauser Effect

Introduction The nuclear overhauser effect is defined as a change in the integrated intensity of one spin when the equilibrium population of another spin is perturbed by saturation or inversion. So, it is the transfer of nuclear spin polarization from one spin-active nucleus to another. However, the nuclei being irradiated…
