Tag: Membrane biology

Over 30% of all cellular proteins are membrane proteins that interact with lipids. This critical relationship between lipids and proteins is fundamental to virtually all biological processes, dictating everything from membrane structure and cellular transport to signal transduction and disease progression.

According to the National Institutes of Health, eukaryotic cells must obtain nutrients from their surroundings to function and grow. The plasma membrane, a semi-permeable barrier, controls all exchanges between the cell and its environment. These essential nutrients are taken in through a variety of sophisticated mechanisms that explain how do cells take up food.
