Question

Some cells produce lipid-soluable products. can you deduce how such products are stores, that is, prevented from exiting the cell?

Answer 1

Lipid soluble cell products include steroids hormones, fat soluble vitamins etc.

As the plasma membrane of cells is made up of lipids, the lipid soluble substances passes through cells and moves inside. Inside cell, these lipid soluble substances are stored in the form of fat bodies/globules. These fat globulins are large in size and cannot pass through cell membrane. Whenever required, these fat globules breaks and release the required substance outside cell.

Also, lipids soluble substances are stored in liver and in adipocytes.
