1 http://www.genomenewsnetwork.org/articles/11_00/crystal_structure_image.shtml All living things are Carbon based. Biomolecules = 4 essential carbon based molecules

2 Organic compounds contain: CARBON & HYDROGEN Organic Molecules include: carbohydrates,carbohydrates, lipids,lipids, ProteinsProteins nucleic acids.nucleic acids.

3 Carbohydrates key source of energy, found in most foods — especially fruits, vegetables, and grains The building blocks of carbohydrates are single sugars, called monosaccharides

4 Carbohydrates Monosaccharide: one sugar unit Glucose is an essential ingredient for the organism to make energy –This happens in both PLANTS & ANIMALS and is known as CELLULAR RESPIRATION

5 Carbohydrates Disaccharide: two sugar unit Examples: –Sucrose (glucose+fructose) –Lactose (glucose+galactose) –Maltose (glucose+glucose) glucoseglucose

6 Carbohydrates Polysaccharide: many sugar units Examples: starch (bread, potatoes) glycogen (beef muscle) cellulose (lettuce, corn) glucoseglucose glucoseglucose glucoseglucose glucoseglucose cellulose

7 Lipids Lipids (LIHP ihdz) are nonpolar molecules that are not soluble in water. (Do not mix with water) include fats, phospholipids, steroids, and waxes. Phospholipids make up the lipid bilayer of cell membranes.

8 Lipids Lipids in the body known as fats are essential for LONG TERM storage of energy Why is a person able to survive for days without food? Can you think of an animal adaptation where long term storage is essential? http://www.jupiterimages.com/popup2.aspx?navigationSubType=itemdetails&itemID=23486696 lipids include some light-absorbing compounds called pigments, such as the plant pigment chlorophyll.

9 Lipids Fatty Acids- monomer of lipids fatty acids There are two kinds of fatty acids you may see these on food labels: 1.Saturated fatty acids: no double bonds (bad) 2.Unsaturated fatty acids: double bonds (good) O C-CH 2 -CH 2 -CH 2 -CH 2 -CH 2 -CH 2 -CH 2 -CH 2 -CH 2 -CH 3 = saturated O C-CH 2 -CH 2 -CH 2 -CH =CH-CH 2 -CH 2 -CH 2 -CH 2 - CH 3 = unsaturated

10 Proteins http://www.parga.gr/dynamic/images/content/Estiatoria/FreshFishSteakSampler-500.jpg A Protein (PROH teen) is a large molecule formed by linked smaller molecules called amino acids A Protein (PROH teen) is a large molecule formed by linked smaller molecules called amino acids. Other proteins are found in skin, ligaments, tendons, and bones. Your hair and muscles contain structural proteins and so do the fibers of a blood clot. Other proteins called antibodies help your body defend against infection.

11 Proteins The membrane of cells is embedded with proteins that serve a variety of functions Proteins can also be Hormones & Enzymes

12 Proteins Proteins are made of long folded chains of Amino Acids

13 Nucleic Acids A nucleic acid is a long chain of smaller molecules called nucleotides. A Nucleotide has three parts: sugar, base, phosphate group,

14 Nucleic Acids DNA or deoxyribonucleic acid, consists of two strands of nucleotides that spiral around each other,

15 Nucleic Acids ATP or Adenosine Triphosphate, Considered by biologists to be the energy currency of life. ATP is the high-energy molecule that stores the energy we need to do just about everything we do.
