Water

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.

Macromolecule info

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.
