Esters are metabolized where?

  1. Liver

  2. Kidneys

  3. In plasma

  4. In tissue

The correct answer is: In plasma

Esters are typically metabolized in the plasma. Esters are organic compounds commonly used in medications and anesthetics. When esters are ingested or administered, they are broken down in the plasma by enzymes called esterases. These enzymes hydrolyze the ester bond in the molecule, leading to the metabolism of esters in the plasma before they are distributed throughout the body for further processing. This process of metabolism in the plasma ensures that the esters are effectively broken down and cleared from the system.
