The cell membrane is a protein-studded phospholipid bilayer that not only protects our cells, but also regulates what goes in and out. In this episode of Crash Course Biology, we’ll look at the structure of the bilayer, learn about its...

The plasma membrane is a complex structure made up of macromolecules that come together to form a fluid mosaic. In this video, we will look at the structure, properties and functions of the fluid mosaic model.

Proteins are complex macromolecules that are considered 1 of the 4 macromolecules that make up life. Proteins have many functions beyond being structural components of cells.

In this video, we explore the basic biochemical mechanism of neuronal death in amyotrophic lateral sclerosis or ALS.
