1. Biochemistry
Carbon => life

2. Carbon bonding Carbon can build complex molecules Covalent bonds
Organic compounds
ATP (Adenosine triphosphate)
Cellular energy
5 carbon sugar, energy locked into bond with phosphate
4 main classes;
Carbohydrates
Lipids
Proteins
Nucleic acids

3. Molecules of Life Different ratios of Carbon, Hydrogen, and Oxygen
Each class has different properties

4. Carbohydrates Carbon, Hydrogen, Oxygen Atoms (1:2:1)
Classified on the number of sugars linked
Monosaccharide or polysaccharide
Used in cells as source of energy, structural materials, and identification
Ex. Chitin, cellulose, fructose, glucose

5. Proteins Carbon, Hydrogen, Oxygen, plus Nitrogen
Chain of amino acid linked together by peptide bonds
Structure, support, movement, communication, transportation, and carrying out chemical reaction (enzyme)
Enzyme brings the reactants together to reduce the amount of energy and time needed for the reaction

6. Lipids Non polar organic molecules
Ex: Phospholipids, steroids, waxes, pigments
Storing energy and water barrier

7. Nucleic Acids
Complex molecules store and transport heredity information
Nucleotide units
Sugar, base, phosphate
DNA (deoxyribonucleic acid) and RNA (ribonucleic acid)
