re: Nicotinamide adenine dinucleotide (NAD)

[Guest guest]

Nicotinamide adenine dinucleotide   (NAD) is a coenzyme found in all living

cells .  

 

 

In metabolism , NAD + 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 – 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.

 

In organisms, NAD + can be synthesized from scratch ( de novo ) from the amino

acids tryptophan or aspartic acid . Alternatively, components of the coenzymes

are taken up from food as the vitamin called niacin .
