β-Nicotinamide Adenine Dinucleotide, reduced form, disodium salt (referred to as reduced nicotinamide adenine dinucleotide disodium salt, commonly abbreviated as NADH disodium salt) is a key coenzyme in organisms and the reduced form of oxidized nicotinamide adenine dinucleotide (NAD?). Its core structure consists of a nicotinamide ring and an adenine ring connected by two phosphate groups. The disodium salt form makes it more stable in aqueous solutions, facilitating storage and use. In biological metabolism, NADH acts as an important electron carrier, participating in energy production (such as glycolysis, the tricarboxylic acid cycle, and oxidative phosphorylation) and various biosynthetic processes through redox reactions (releasing electrons to convert to NAD?).

Main Application Scenarios

1. Biochemistry and molecular biology research

 As a coenzyme in enzymatic reactions, it is used to reconstruct metabolic pathways in vitro (such as mitochondrial respiratory chain reactions) and study enzyme activity and functions (such as the catalytic mechanism of dehydrogenases). - As a reducing agent, it participates in in vitro synthesis or modification experiments of biological molecules such as nucleic acids and proteins.

2. Pharmaceutical and clinical fields

-Investigating its potential therapeutic effects in diseases related to energy metabolism disorders (such as mitochondrial diseases and neurodegenerative diseases), for example, improving cellular energy supply by supplementing NADH. - Being a research object as an antioxidant to explore its mechanisms of scavenging free radicals and protecting cells from oxidative damage (such as its application potential in cerebral ischemia and myocardial injury).

3. Food and health product industry

As an ingredient in nutritional supplements, it is claimed to alleviate fatigue (by participating in energy metabolism) and enhance immunity, but the relevant efficacy requires more scientific verification.

4. Cosmetics field

Due to its antioxidant properties, it is added to skincare products to delay skin aging (such as reducing the damage of free radicals to collagen). In summary, the applications of NADH disodium salt revolve around its key role in energy metabolism and redox reactions, covering multiple fields such as scientific research, medicine, and health.
