Product Function
• Energy Metabolism: Riboflavin is a key component of flavoproteins, such as flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN). These coenzymes play a vital role in many metabolic pathways related to energy production. For example, in the citric acid cycle, FAD and FMN participate in oxidation - reduction reactions that help break down nutrients like carbohydrates, fats, and proteins to generate ATP (adenosine triphosphate).
• Antioxidant Defense: As part of the glutathione reductase enzyme system, riboflavin helps maintain the antioxidant status of cells. Glutathione reductase, with its flavin cofactor, regenerates reduced glutathione, which scavenges free radicals and protects cells from oxidative damage.
• Cellular Function and Growth: Riboflavin is necessary for proper cell growth, division, and function. It is involved in the synthesis of DNA, RNA, and proteins, which are essential for building and maintaining tissues in the body.
Application
• Food Industry: Riboflavin is used as a food additive, mainly as a coloring agent. It gives a yellow - orange color to foods such as cereals, drinks, and dairy products. This not only enhances the visual appeal of the products but also enriches them with a source of vitamin B₂.
• Pharmaceutical Industry: In the pharmaceutical field, riboflavin is used to prevent and treat riboflavin deficiency disorders. Supplements are available in various forms such as tablets, capsules, and injections to address conditions caused by insufficient intake of this vitamin.
