Description: Vitamin B3, commonly referred to as niacin, is a water-soluble vitamin that shares many similarities with vitamin B2. It plays a critical role in the metabolism of proteins, carbohydrates, and fats. Niacin is a component of nicotinamide adenine dinucleotide (NAD), which is essential for energy production in cells through the Kreb’s cycle and electron transport chain. NAD is also involved in the production of other vital macromolecules, including cholesterol and fatty acids​​. Functions: Niacin is crucial for the production of ATP through its role in the Kreb’s cycle and electron transport chain. It helps in the synthesis of cholesterol, fatty acids, and other macromolecules essential for optimal body function.
