1. Bio-Chemistry Biology 1

2. Carbon – is found in all living things. 4 electrons in its outer energy level Carbon has the ability to bond with many different elements.

3. When carbon bonds to each other, they can bond in the following ways Rings Straight chains Branched chains

4. Organic Compounds that contain carbon 1. Carbohydrates 2. Lipids 3. Proteins 4. Nucleic Acids Organic Compounds

5. Carbohydrates Composed of carbon, hydrogen and oxygen C – H - O 1:2:1 ratio Used for energy for the body Examples: Monosaccharide Disaccharide Polysaccharide

6. Monosaccharide Simple carbohydrate Single sugar Glucose Fructose Glucose

7. Disaccharide Double sugar formed by the combination of two simple sugars Sucrose = glucose + fructose Formed by condensation synthesis Sucrose

8. Polysaccharide Large molecule formed when many monosaccharide’s link together 1. Starch Made from plants Puts glucose in a chain 2. Glycogen Found in livers as stored food Puts glucose in a branched chain 3. Cellulose Found in cell walls of plant cells Puts glucose in a chain linked fence form

10. Organic Compounds (con’t) Lipids C - H - O Used for food storage, insulation and protection Lipids are insoluble because their molecules are non-polar Examples: Oils, fats waxes and steroids Unsaturated lipids Contain double bonds between the carbon atoms Saturated lipids Contain all single bonds between the carbon atoms

12. Organic Compounds (con’t) Proteins C - H – O - N Essential for life Provide Structure for tissues and organs Make enzymes A protein that changes the rate of chemical reactions Amino Acids are building blocks for proteins Amino Acids are linked together by forming a peptide bond Number and order of amino acids determines the proteins

14. Organic Compounds (con’t) Nucleic Acids C-H-O-N-P Stores genetic information in the form of a code Examples: DNA & RNA Made of units called nucleotides Phosphate Group Ribose Sugar Nitrogen Base
