Microsomes

Microsomes are tiny, artificial structures created from pieces of the endoplasmic reticulum, a cell's internal network involved in making and processing proteins and fats. When cells are broken apart, microsomes form from fragments of the endoplasmic reticulum that contain enzymes responsible for breaking down drugs, toxins, and other substances. They are used in laboratories to study how drugs are metabolized, as they mimic the natural processes that happen in the body’s cells. Essentially, microsomes serve as a useful tool for understanding how substances are processed in the liver and other organs.
