Riboflavin (Vitamin B2) is an essential water-soluble vitamin involved in cellular energy production, enzyme function, and the metabolism of fats, drugs, and steroids. This 1kg reagent is widely used in biochemical research to study metabolic processes, particularly those involving mitochondrial energy production and redox reactions. Riboflavin is also crucial for the synthesis of flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), both of which are coenzymes in various enzymatic reactions. In laboratory applications, Riboflavin is used in assays involving redox chemistry, UV light studies, and research on vitamin deficiencies, cellular respiration, and energy metabolism.
