Absorption, Distribution and Excretion
Ingested diphosphate is readily converted to monophosphate; no diphosphate was found in feces or urine of rats treated with diets containing up to 5% tetrasodium diphosphate. In these experiments diphosphate was almost completely absorbed by the gut and excreted as monophosphate in the urine. /Diphosphate/ /Ortho/ phosphate is absorbed from, and to a limited extent secreted into, the gastrointestinal tract. Transport of phosphate from the gut lumen is an active, energy-dependent process that is modified by several factors. ... Vitamin D stimulates phosphate absorption, an effect reported to precede its action on calcium ion transport. In adults, about two thirds of the ingested phosphate is absorbed, and that which is absorbed is almost entirely excreted into the urine. In growing children, phosphate balance is positive. Concentrations of phosphate in plasma are higher in children than in adults. This "hyperphosphatemia" decreases the affinity of hemoglobin for oxygen and is hypothesized to explain the physiological "anemia" of childhood. /Phosphates/ Metabolism / Metabolites In the animal body, diphosphate is formed from adenosyl triphosphate (ATP) in many enzymatic reactions. It is either utilized by entering phosphorolytic reactions, or it is hydrolysed by an inorganic diposphatase to monophosphate. /Diphosphate/ A defect in phosphate metabolism occurs in a variety of diseases. ... Rickets ... Osteomalacia ... Primary or Secondary Hyperparathyroidism ... Chronic Renal Failure. /Phosphates/ |

Interactions
This paper summarizes data on the factors involved in addiction and dependence to cigarettes. Nicotine has been intensively studied by the tobacco industry, for instance for its addictive effect at the lowest possible rates. The addition of diammonium phosphate and urea produces an alcalinization of the pH of cigarette smoke, and promotes the absorption and the trans-membrane passage of nicotine. The taste, the smell of smoke, and the visual aspect of the pack of cigarettes are also sensory components that promote addiction. Finally, menthol, sugar, cocoa and liquorice added to cigarettes also play a role in dependence and addiction to cigarettes by, for instance, making an anesthetic effect on the airways.

Ammonium phosphate is a white solid with a weak odor of ammonia. Sinks and mixes with water. (USCG, 1999)
Diammonium hydrogen phosphate is an inorganic phosphate, being the diammonium salt of phosphoric acid. The commercially available fertilizer has an analysis of 18-46-0 (N-P2O5-K2O) and is marketed under the name diammonium phosphate or DAP. It has a role as a fertilizer. It is an inorganic phosphate and an ammonium salt. See also: Phosphate Ion (has active moiety) ... View More ... |

1、根据实验需要选择合适的溶剂配制储备液 (母液)：对于大多数产品，InvivoChem推荐用DMSO配置母液 (比如：5、10、20mM或者10、20、50 mg/mL浓度），个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息，或者很难将产品溶解在溶液中，请联系我们;
3、建议使用下列计算器进行相关计算（摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等）;
4、母液配好之后，将其分装到常规用量，并储存在-20°C或-80°C，尽量减少反复冻融循环。
计算结果:
工作液浓度： mg/mL；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度，请首先与我们联系。
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL ddH2O，混匀澄清。
(1) 请确保溶液澄清之后，再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶；
(2) 一定要按顺序加入溶剂 (助溶剂) 。
