Nicotinamide (Vitamin PP) in this 250g package is a high-purity reagent used in various biochemical and pharmaceutical applications. It is essential for the synthesis of NAD+ (Nicotinamide adenine dinucleotide), a coenzyme that plays a central role in cellular respiration and energy production. This reagent is commonly used in laboratory studies on metabolic pathways, enzymatic processes, and cellular signaling mechanisms. It also has therapeutic uses, particularly in dermatology, where it is included in formulations for skin health and anti-aging treatments. Researchers rely on nicotinamide for its stability and effectiveness in various experimental protocols.
