Organic Molecules

Organic Molecules are…. Molecules that contain carbon

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.

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 sugars EX: 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. fruit potatoes pasta honey exoskeleton

Chitin does which of the following functions? Energy storage in animals Support in exoskeletons of arthropods Energy storage in plants Support for plant cells

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

Phosphate group, 2 fatty acids & glycerol Ex. Phospholipid Phosphate group, 2 fatty acids & glycerol

A. Carbohydrate B. Lipid C. Amino Acids D. Hydrolysis Long-term, back-up energy storage and insulation are the functions of which biomolecule? A. Carbohydrate B. Lipid C. Amino Acids D. Hydrolysis

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 Peptide bond Amino acids are joined together to form protein The bond between amino acids is called a PEPTIDE BOND. Peptide bond

If you put many of these molecules together (by removing water), what larger molecule will they form? A. Protein B. Carbohydrate C. Lipid D. Nucleic Acid

4. Nucleic Acids Function: Store, transmit, and transfer genetic information Examples: DNA & RNA Elements: Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus

Monomer Nucleotide (3 parts)

Polymer
