Chemistry of Life
Water that is attracted to water itself is called cohesion. Water that is attracted to other substances is called adhesion. Electrons that are not shared equally in a covalent bond are water molecules that are polar. The PH levels of water are: pure water= about 7, acid= under 7, and bases= 7 and above. Water is also a neautral.
This is the process of cohesion when water is attracted to water itself
This is the process of adhesion when water is attracted to other substances besides water
This is the water molecule (AKA Mickey Mouse)
Macromolecules are large and is made up of small organic molecules. There are four types of this kind of molecule: Carbohydrates (AKA carbs), Lipidus, Proteins, and Nucleic Acid. The base of Carbohydrates are Carbon (C), Hydrogen (H), Oxygen (O), and sometimes Nitrogen (N).
- Carbohydrates provide energy for the body. Enzymes help break down carbs and turn them into glucose.
- Proteins help cells function and they are also made of antibodies
- Lipids store energy and helps our body break down fats from our digestive track and form them into fatty acids.
- Nucleic Acid comes from DNA and RNA. DNA stores gentic information thats cells need to function in the body. RNA converts information from our DNA to proteins.
