NADP+, or nicotinamide adenine dinucleotide phosphate, is a coenzyme found in all living cells. It plays a crucial role in various biochemical reactions, particularly in the process of photosynthesis in plants. NADP+ acts as an electron carrier, helping to transfer energy during the conversion of light energy into chemical energy. In addition to its role in photosynthesis, NADP+ is involved in anabolic reactions, which are processes that build larger molecules from smaller ones. It is essential for the synthesis of fatty acids and nucleic acids, making it vital for cell growth and reproduction.
