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.

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 a derivative of Vitamin B3 (Niacin/Nicotinamide) while FADH2 is a derivative of Vitamin B2 (Riboflavin). This is the key difference between NADH and FADH2. contents
