Organic Molecules Molecules that contain carbon Essential Question: What is the structure and function of the 4 groups of organic compounds? Carbon is important to living organisms for several reasons. Carbon

is found in all living things Complex molecules are made up of carbon bonding with

other elements to make biological building blocks Building blocks link together to form complex molecules Monomers are building blocks. Monomers bond together to form

long chains called polymers. Building blocks link together to form complex molecules 4 types of Biomolecules Carbohydrates Lipids Proteins

Nucleic acids 1. Carbohydrates Sugars, starches and fibers found in fruits, grains,

vegetables and milk products. Function Quick/short-term energy Energy storage Structure

Elements (C,H,O) Carbon Hydrogen Oxygen Monomer: Monosaccharide Simple EX:

sugars glucose, fructose, galactose Polysaccharides many monomers joined together Starch

energy storage in plants Glycogen energy storage in animals Cellulose support for plant cell walls Chitin support in exoskeletons of arthropods EX: Carbohydrates Identify each example as a

monosaccharide or polysaccharide. potatoes fruit pasta exoskeleton

honey 2. Lipids A group of biological molecules that generally do not dissolve in water

Found in Vegetable oil Animal fats Waxes Cell Membranes Steroids/Hormones

Candle wax Lipid bilayer of cell membrane Function Insulation Protection Long

term energy storage Elements (C, H, O) Carbon Hydrogen Oxygen Monomers Glycerol

Fatty acids Polymer Ex. Triglyceride = Glycerol and three fatty acids

Ex. Phospholipid Phosphate group, 2 fatty acids & glycerol 3. Proteins Large, complex molecules that play many

critical roles in the body Found in muscle skin hair

Functions Structure Speed up chemical reactions (enzymes) Regulate body processes (antibodies & hormones)

Elements (C, H, O, N) Carbon, Hydrogen, Oxygen, and Nitrogen Monomer Amino Acids

(20 different kinds) Polymer Amino acids are joined together to form protein The

bond between amino acids is called a PEPTIDE BOND. Peptide bond 4. Nucleic Acids Function:

Store, transmit, and transfer genetic information Examples: DNA & RNA Elements: Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus Monomer Nucleotide
