Macromolecules Macromolecules are the BASIC STUFF OF LIFE!! Benchmark SC.912.L.18.1 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

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-

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

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

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
