NADP sodium salt is the sodium salt form of NADP (HY-113325). NADP is a coenzyme involved in cellular electron transfer reactions in biological metabolism, which is alternately oxidized (NADP+) and reduced (NADPH), and can maintain cellular redox homeostasis and regulate many biological events, including cellular metabolism. NADPH is a universal electron donor that provides reducing ability for synthetic metabolic reactions and redox balance. NADPH plays a multifunctional role in regulating inflammation, redox homeostasis, and synthetic metabolism processes[1][4].

Adenine (Standard) is the analytical standard of Adenine. This product is intended for research and analytical applications. Adenine (6-Aminopurine), a purine, is one of the four nucleobases in the nucleic acid of DNA. Adenine acts as a chemical component of DNA and RNA. Adenine also plays an important role in biochemistry involved in cellular respiration, the form of both ATP and the cofactors (NAD and FAD), and protein synthesis.

Pyridoxal (Standard) is the analytical standard of Pyridoxal. This product is intended for research and analytical applications. Pyridoxal is a neuroprotectant. Pyridoxal is one of the main forms of vitamin B6. Pyridoxal is phosphorylated by pyridoxal kinase to pyridoxal phosphate (HY-B1744). Pyridoxal is oxidized by the liver to 4-pyridoxic acid (HY-113493) and excreted in the urine. Pyridoxal has shown promise in the study of carpal tunnel syndrome (CTS)[1][2][3].

Menaquinone-4 (Standard) is the analytical standard of Menaquinone-4. This product is intended for research and analytical applications. Menaquinone-4 is a vitamin K, used as a hemostatic agent, and also a adjunctive therapy for the pain of osteoporosis.
