PRESENTATION OUTLINE
CARBOHYDRATE
- A carbohydrate is an organic compound composed of hydrogen, carbon, and oxygen.
- It is divided into monomers called monosaccharides, which can then join to make disaccharides.
- Disaccharides can then join with other disaccharides to make polysaccharides.
- The body uses carbohydrates for energy and structural support.

EXAMPLES OF CARBOHYDRATES
- Fructose, galactose, and glucose that are found in:
- Syrup
- Graham Crackers
- Fruit
- Gatorade

LIPID
- Lipids are large, non polar organic molecules.
- A monomer of a lipid is called a triglyceride.
- A triglyceride is composed of glycerol and three fatty acid chains.
- Lipids are composed of carbon, hydrogen, and oxygen.
- Lipids serve as the cuticles on plants, pigments, and steroids.

- Food that contains saturated/unsaturated fats:
- Coconut
- Butter

PROTEIN
- Proteins are large polymers that are composed of one or more amino acid chains.
- Amino acids are the made up of 2 functional groups called a carboxyl group and an amino group.
- Proteins act as enzymes that help to control metabolic reactions and control functions in cells.
- A protein is composed of carbon, nitrogen, oxygen, and hydrogen.
Nucleic Acid
- Nucleic acids are polymeric macromolecules.
- Nucleic acids have monomers called nucleotides.
- Nucleic acids carry the genetic material in the body and are essential for life.
- Nucleic acids are composed of carbon,hydrogen,nitrogen,oxygen, and phosphorus.
