NADP, or Nicotinamide Adenine Dinucleotide Phosphate, is a coenzyme that plays a significant role in numerous metabolic processes. It exists in two forms: NADP+ (oxidized) and NADPH (reduced). The primary function of NADP is to act as an electron carrier, facilitating redox reactions in cells. It is especially critical in anabolic reactions, including lipid and nucleic acid synthesis.
