Niacin is also involved in the synthesis of protein, fat, and pentoses needed for nucleic acid formation. Niacin is a major constituent of the coenzyme nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP).These compounds function to remove hydrogen atoms during biological reactions.iacin is also involved in the synthesis of protein, fat, and pentoses needed for nucleic acid formation.

Nicotinamide Adenine Dinucleotide (NAD) is a dinucleotide that functions as one of the most important coenzymes in the cell. The interconversion of NAD between the reduced (NADH) and oxidized (NAD+) forms is a common reaction in biological redox (oxidation-reduction) reactions. In cells, most oxidations are accomplished by the removal of hydrogen atoms. Each molecule of NAD+ can acquire two electrons; that is, be reduced by two electrons.
