Produktbeschreibung：

Nucleotides have important biological functions. They are a class of compounds composed of three substances: purine base or pyrimidine base, ribose or deoxyribose, and phosphoric acid. They are mainly involved in the formation of nucleosides.

Adenosine triphosphate (ATP) is considered to be a universal energy source that is essential for cell synthesis in the survival and reproduction of all organisms. ATP can be produced through a variety of cellular pathways. The most typical example is synthesis by adenosine triphosphate synthase through oxidative phosphorylation in mitochondria, or synthesis by photosynthesis in plant chloroplasts. The main energy sources for ATP synthesis are glucose and fatty acids.

Adenosine diphosphate (ADP) is widely present in animals, Pflanzen, Mikroorganismen, und kultivierte Zellen. In organisms, ADP is a product of breaking a high-energy phosphate bond (ATP) hydrolyzed to lose a phosphate radical) and releasing energy.

Adenosine monophosphate (AMP) ist bei Tieren weit verbreitet, Pflanzen, Mikroorganismen, und kultivierte Zellen. It is formed after ATP and ADP release energy in the body. It can continue to bind phosphate groups to form adenosine diphosphate (ADP) and adenosine triphosphate (ATP). It is the product of incomplete hydrolysis of ATP.

ATP 、 ADP 、 AMP have an absorption peak at 254 nm, and their content can be determined by high-performance liquid chromatography.

Notiz:

Vorsichtsmaßnahmen:

1. After the detection, the chromatographic column needs to be flushed with high-concentration ultrapure water (um 20-30 column volumes) to prevent clogging the chromatographic column. Endlich, flush the column according to the specifications of the column to prevent damage to the chromatographic
2. The dilution factor of the standard should be determined according to the concentration of nucleotides in the sample. The peak area of nucleotides in the sample must be within the peak area of the standard solution of different concentrations. The dilution factor of the standard is only a reference. If the nucleotide concentration in the sample is too high, it is recommended to dilute it before
3. The sample after extraction is not stable at room temperature, so it needs to be operated as soon as possible.
4. If the sample number is too large, it is recommended to test the standard solution once a day (one standard solution is sufficient) to determine the corresponding retention
