Below is a brief overview of the key components of Iran's government and political system. At the top of Iran's power structure is the Supreme Leader, Ayatollah Ali Khamenei, who succeeded Ayatollah Ruhollah Khomeini, the father of the Iranian Revolution, upon Khomeini's death in 1989. Khomeini and Khamenei are the only two men to have held the office since the founding of the Islamic Republic in 1979.
NADH, short for nicotinamide adenine dinucleotide, is an important pyridine nucleotide that functions as an oxidative cofactor in eukaryotic cells.NADH plays a key role in the production of energy through redox reactions.icotinamide adenine dinucleotide (NAD) is one of the most important coenzymes in the cell. Not surprisingly, NAD and the closely related NADP are the two most abundant cofactors in eukaryotic cell.
NADH is the abbreviation used for Nicotinamide Adenine Dinucleotide, one of the most important coenzymes in the human brain and body. A coenzyme is the active, or working form of a vitamin. NADH is the reduced (electron-energy rich) coenzyme form of vitamin B3, while NAD is the oxidized (burned) coenzyme form of B3.NAD and NADH are converted into each other in numerous different metabolic activities.t is vitamin B3 (niacinamide) combined with a ribose (5-carbon sugar), a phosphate group and an adenine nucleotide (a DNA component). NAD(H) can be made in the liver and other cells from vitamin B3. It can also be made from the amino acid L-Tryptophan at the expensive ratio of 60mg tryptophan for 1mg B3.
