The phospholipid bilayer of the cell membrane protects the cell, provides structural support and controls the flow of molecules into and out of the cell.

Water is highly organized by contact with the double layer of membrane lipids. Hydrophilic phosphates of the phospholipids hydrogen bond into the water surface layers.

What are the different kinds of lipids? What is the difference between saturated and unsaturated fats? Read on and discover.

What is the difference between an organic and an inorganic molecule? What substances are within the realm of organic chemistry? Read on and discover.

Cell outer membranes regulate and transport materials into and out of cells. Without membranes there would be no life as it is now known and understood by scientists

The cell's endomembrane system consists of the rough and smooth ER, Golgi apparatus, vesicles and plasma membrane, all working together to transport cellular materials.

The tough fibers that span cells and hold the nucleus together are intermediate in diameter between thin actin microfilaments and thick microtubules of the cytoskeleton.

Cell membranes once seemed to be simple cell structures. Today, membranes are recognized as complex, highly-organized structures that still require intensive research.

The eukaryotic cells of plants and animals possess several critical differences from prokaryotic cells, including a nucleus and other membrane-bound organelles.

What specifically are the similarities between prokaryotic and eukaryotic cells? Here is a side by side comparison to simplify mastery of the basics of cell structure.

Bacteria and viruses are both tiny infectious agents with the ability to cause disease. So it is not surprising that these microbes are sometimes mistaken as the same.

What specifically are the main differences between prokaryotic and eukaryotic cells? Here is a side by side comparison to simplify mastering the basics of cell structure.

Prokaryotes are evolutionarily ancient, for billions of years the only form of life. Here's a summary of the basic "parts & pieces" of these primitive cells.

Retroviruses are a diverse group of RNA-containing viruses that contribute to several human diseases. They may one day be exploited to cure illnesses, too.

Everyone has heard of cholesterol but few understand where it comes from and how important this much maligned molecule is for life.

Molecules that form hydrogen bonds with water are hydrophilic and those that can't are hydrophobic.
