<p>3-Indoxyl sulfate, potassium salt (3ISK) is a chemical compound that is soluble in water. It has been used as a marker for bowel disease, and it has been shown to react with analytical methods such as titration calorimetry and lc-ms/ms. 3ISK can be used to determine the optimum concentration for pharmacological treatment of bowel disease. The metabolic fate of 3ISK has been studied extensively and it is found that 3ISK is metabolized by microbial enzymes in the gut, which may lead to an increased incidence of bowel disease in patients with low levels of microbial metabolism. 3ISK also plays an important physiological function by maintaining mitochondrial membrane potential, which could have implications for pharmacological treatment of bowel disease.</p>
