Question

What is NADH made of?

Answer 1

In order to answer this question, we will go through the complete explanation of NAD including the exact name for it. And then we will discuss much more such as what is the purpose of NADH in cellular respiration.

Complete answer:
NADH is a dinucleotide made up of the bases of adenine and nicotinamide. The 5′ phosphate groups connect the two nucleotides. It's a coenzyme that's found in all living things and plays a role in a variety of metabolic activities, including cellular respiration. It is a type of $NAD +$ that has been decreased.
The coenzyme nicotinamide adenine dinucleotide (NAD) is essential for metabolism. NAD is a dinucleotide that is found in all living cells and is made up of two nucleotides connected by their phosphate groups. The adenine nucleobase is present in one nucleotide, while nicotinamide is present in the other. The oxidised and reduced forms of NAD are denoted as $NAD +$ and NADH ( $H$ for hydrogen), respectively.
Nicotinamide adenine dinucleotide is engaged in redox processes in metabolism, transporting electrons from one reaction to the next. As a result, the cofactor can be found in two forms in cells: $NAD +$ is an oxidising agent, which means it takes electrons from other molecules and reduces them. This reaction produces NADH, which can subsequently be employed to give electrons as a reducing agent. NAD's primary role is electron transfer processes. It is also used in various biological activities, most notably as a substrate for enzymes that add or remove chemical groups from proteins during post translational modifications. Because of the importance of these tasks, pharmacological development is focusing on enzymes involved in NAD metabolism.

Note:
- In eukaryotes, NAD ( Nicotinamide Adenine Diphosphate ) is a coenzyme involved in cellular respiration. NAD's major job is to transport hydrogen and electrons from one process to the next. This chemical occurs naturally in the body and plays a role in the chemical process that generates energy. People use NADH supplements as medicine.
