4 types of Chemical Bonds in Biology
There are four types of chemical bonds essential for life to exist: Ionic Bonds, Covalent Bonds, Hydrogen Bonds, and van der Waals interactions. We need all of these different kinds of bonds to play various roles in biochemical interactions. These bonds vary in their strengths. In Chemistry, we think of Ionic Bonds and Covalent bonds as having an overlapping range of strengths. But remember, in biochemistry, everything is happening in the context of water. This means Ionic bonds tend to dissociate in water. Thus, we will think of these bonds in the following order (strongest to weakest): Covalent, Ionic, Hydrogen, and van der Waals. Also note that in Chemistry, the weakest bonds are more commonly referred to as “dispersion forces.”

Course Description
Biology is the study of Life. In this course, we will explore topics in Biochemistry, Cell Biology, Genetics, Molecular Biology, Viruses, Evolution, Bacteria and Archaea, Protists, Plants (Botany), Fungi, Animals (Zoology), Anatomy & Physiology,Reproduction, Development, Animal Behavior, and Ecology. This course is designed for advanced High School Students (AP Biology) and first and second-year college students. Many topics in modern biology are dependent on an understanding of Chemistry - we encourage you to explore our Chemistry playlist as well!
