What is Biochemistry, and what do biochemists study? What is covered in this field, as opposed to Molecular Biology or Cell Biology? The truth is, there’s a lot of overlap in these disciplines. But in general, biochemistry is the study of the chemistry of life.

What’s so special about the molecules of life? It’s a case of emergent properties. When biochemical molecules interact, unexpected complexities arise! Phospholipids form the bilayers found in cells. These compartments allow for high concentrations of chemical reactions to take place, leading to...life.

The four main types of biological molecules studied by biochemists are proteins, carbohydrates, lipids, and nucleic acids. This video briefly introduces these topics, and each one will be covered in more depth in their own videos.

Our series on Biology is aimed at the first-year college level, including pre-med students. These videos should also be helpful for students in challenging high school biology courses. Perfect for preparing for the AP Biology exam or the Biology SAT. Also appropriate for advanced homeschoolers. You can also follow along if you are just curious, and would like to know more about this fascinating subject.

Our current biology textbook recommendation is Campbell Biology from Pearson.

About our instructor:
Kimberly Hatch Harrison received degrees in Biology and English Literature from Caltech before working in pharmaceuticals research, developing drugs for autoimmune disorders. She then continued her studies in Molecular Biology (focusing on Immunology and Neurobiology) at Princeton University, where she began teaching as a graduate student. Her success in teaching convinced her to leave the glamorous world of biology research and turn to teaching full-time, accepting a position at an exclusive prep school, where she taught biology and chemistry for eight years. She is now the head writer and producer of Socratica Studios.
