-Storage conditions: 2-8 ° C, dark, dry and sealed storage; Solid requires -20 ° C for long-term use, preferably

Main functions and applications
1. Energy metabolism: As a dehydrogenase coenzyme, it reversibly transfers hydrogen (H ⁺/e ⁻) in the tricarboxylic acid cycle and respiratory chain, participating in processes such as glycolysis and fatty acid oxidation.
2. Biosynthesis regulation: It affects the metabolism of nucleic acids, proteins, and polysaccharides, and is a substrate for signaling enzymes such as PARP and sirtuins.
3. Scientific research and pharmaceutical applications: used as biochemical analysis standards and cell metabolism research reagents; Some preparations are used as adjuvant therapy for myocarditis, leukopenia, etc. (follow medical advice).

Precautions
-The aqueous solution is weakly acidic (pH ≈ 3.0) and is prone to decomposition and failure when exposed to alkali or heating;
-Highly hygroscopic, it should be quickly sealed after opening to avoid repeated freezing and thawing;
-Non CoA (Coenzyme A), the two have different structures and functions, please do not confuse them.
