Macromolecules are the
BASIC STUFF OF LIFE!!
Carbohydrates-Lipids- Proteins – Nucleic Acids
They Begin as MONOMERS- simple form and build into their longer form POLYMERS

2. Carbohydrates
Monomer -
Used for energy , or other specific purposes depends on carb.
Structure C, H, O
EXAMPLES: Monomer- Sugar, Glucose, Fructose
Disaccharide-Sucrose
Polysaccharide-Glycogen, Starch, Cellulose
Polymer-

3. Lipids Used for energy or cell structure or insulation, warmth
Structure varies

4. Monomer: Amino Acid
Proteins
Used in almost all cell function, many have very specific functions
Only one with Nitrogen
Structure: C, H, O, N and sometimes S
Polymer: PROTEIN

5. Nucleic Acids Used to build RNA and DNA (our genetic code)
Monomer: Nucleotide
Used to build RNA and DNA (our genetic code)
Nucleic Acids participate in the process of Protein Synthesis.
Polymer: Nucleic Acid – DNA
