About NAD 500MG
NAD⁺ (Nicotinamide Adenine Dinucleotide, Oxidized Form) is a crucial coenzyme found in all living cells, playing a central role in redox reactions, energy metabolism, and cellular signaling. In research, NAD⁺ is widely used as a biochemical reagent to investigate oxidative pathways, enzyme catalysis, and cellular aging mechanisms. Its essential function in metabolic regulation and mitochondrial activity makes NAD⁺ a cornerstone compound in molecular biology, enzymology, and longevity studies. This high-purity lyophilized form is optimized for consistent results in in vitro and in vivo experimental models, providing a reliable standard for investigating the biochemical foundations of life.
Mechanism of Action
The mechanism involves NAD⁺ acting as a primary electron carrier in redox reactions. During cellular respiration, NAD⁺ accepts electrons from metabolic substrates, becoming reduced to NADH. This NADH then provides the electrons needed for the electron transport chain in the mitochondria to produce ATP. Furthermore, NAD⁺ acts as a signaling molecule and cofactor for Sirtuins (longevity-linked enzymes) and PARPs (DNA repair enzymes). By donating its ADP-ribose moiety, NAD⁺ enables these enzymes to regulate gene expression, maintain genomic stability, and optimize cellular stress responses in research assays.
