NADH (Nicotinamide Adenine Dinucleotide, reduced form, disodium salt) is a coenzyme vital for biochemical research, particularly in cellular metabolism studies. This 1-gram quantity is commonly used in enzymatic reactions, redox processes, and assays that require a high-energy molecule. NADH plays a crucial role in energy transfer and cellular respiration, making it indispensable in studies related to mitochondrial function, metabolic diseases, and pharmacological research. The disodium salt form ensures better solubility in aqueous solutions, making it easier to handle and incorporate into experiments for accurate and reproducible results.
