One of the most famous speeches given by a sitting American President, although it lasted just a little over seven and a half minutes, it managed to stir a nation's patriotism to the very bone and was a significant point in American history.
In metabolism, nicotinamide adenine dinucleotide is involved in redox reactions, carrying electrons from one reaction to another. The coenzyme is, therefore, found in two forms in cells: NAD + is an oxidizing agent â it accepts electrons from other molecules and becomes reduced.This reaction forms NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD.hese preformed components then pass through a salvage pathway that recycles them back into the active form. Some NAD is also converted into nicotinamide adenine dinucleotide phosphate (NADP); the chemistry of this related coenzyme is similar to that of NAD, but it has different roles in metabolism.
Many contain the nucleotide adenosine monophosphate (AMP) as a component of their structures, for example, ATP, coenzyme A, FAD, and NAD+. Coenzyme A substance that becomes essential for the working and function of an enzyme other than the protein compounds becomes known as a coenzyme.
