Organic Molecules – large molecules that make up all living organisms. 1. Carbohydrates 2. Lipids 3. Proteins 4. Nucleic Acids

Simple Sugars – 1 sugar molecule Complex Sugars – many sugar molecules Carbohydrates Structure: Simple Sugars – 1 sugar molecule Complex Sugars – many sugar molecules Function – main source of energy for living things

Carb. Examples Simple Carbs – glucose Complex Carbs: Glycogen – in animal muscles and liver. Starch & Cellulose – found in plant cells.

Function – store energy, cushioning, insulation, waterproofing. Lipids Structure – carbon based molecules that are water fearing “hydrophobic” Function – store energy, cushioning, insulation, waterproofing.

Fats: lards, butter (animals) room temp Lipid Examples Fats: lards, butter (animals) room temp Oils: cooking oil (plants)

Structure – carbon based molecules made up of amino acids Proteins Structure – carbon based molecules made up of amino acids Function – speed up chemical reactions; construction workers of a cell; supervisors of a cell; communication workers of a cell

Muscles, Nails, Hair and Enzymes Protein Examples Muscles, Nails, Hair and Enzymes

Structure – made up of nucleotides Nucleic Acids Structure – made up of nucleotides Function – store info on how to make proteins (DNA) & help make the proteins (RNA).

Nucleic Acids Examples DNA RNA
