Would you expect guaifenesin to be readily absorbed from and along the gastrointestinal tract after oral administration? Draw the structure of guaifenesin in the stomach (pH = 2)
Homework Answers
Guaifenesin is a glyceryl gluaiacolate with expectorant effects. This is usually taken to assist the expectoration (bringing up) of phlegm along from the airways in acute respiratory tract infections.It also reduces the viscosity of mucus secretion by reducing adhesiveness and surface tension as well as increasing the hydration of mucus.
Yes, it is readily absorbed from the gastrointestinal tract and rapidly metabolized and excreted in the urine. It is soluble in water. It is equally absorbed by all parts of gastrointestinal tract and action takes place through stimulation of gastrointestinal tract.

During surgery acetylcholine function is blocked to switch off muscle stimulation including of the gastrointestinal tract and urinary bladder. With reference to acetylcholine's structure and stability, suggest why oral administration or intravenous injection of acetylcholine after surgery can not be used to switch back on the muscle stimulation [2 marks] Bethanechol is an acetylcholine agonist that can be used to switch back on muscle 11 stimulation after surgery. Show how bethanechol can act as an acetylcholine agonist AND also provide...

Il. PARTS OF THE DIGESTIVE TRACT A. ORAL CAVITY After ingestion, the physical breakdown of solid foods (mechanical digestion) begins in the oral cavity (mouth). Describe how food is mechanically digested in the oral cavity. Include a discussion of how the teeth, tongue, and saliva work together to convert solid food into a moist, semi-solid mass of food called a bolus. Example: think of how a hard, dry saltine cracker is converted into a moist ball (bolus) in the mouth...

1. a. Many medications are absorbed into the blood through the cells lining the stomach and small intestine. The rate of absorption (passage through a cell membrane into the blood stream) for a molecule depends on the structure and properties of the molecule. Which substance would be more easily absorbed into the blood stream; a polar, ionic, or nonpolar substance? Choose one and justify your reasoning using chemical and molecular details. b. Furosemide is a diuretic used to treat fluid...
