Molecular Biology

Learn about macromolecules, lipids, proteins and other molecular components of the cell.
Protein Function
Proteins are very important molecules in our cells. Each protein within the body has a specific function.
Diffusion, Passive Transport, and Osmosis
Diffusion is the tendency of molecules to spread into an available space. Without other outside forces at work, substances will move/diffuse from a more concentrated environment to a less concentrated environment.
Macromolecules
An introduction to macromolecules and molecular diversity.
Carbohydrates
An introduction to the structure and function of carbohydrates.
Lipids
Lipids are very diverse in both their respective structures and functions. Examples of lipids include fats, phospholipids and steroids.
Nucleic Acids
Nucleic acids allow organisms to transfer genetic information from one generation to the next.
Proteins
Proteins are very important molecules in cells. They have many diverse functions and all are typically constructed from one set of 20 amino acids.
