1. 2.3 Carbon Compounds

2. Carbon has 4 valence electrons so they are strong covalent bonds with many other elements including itself Carbon-carbon bonds The Chemistry of Carbon

3. Macromolecules (giant molecules) Made from thousands or hundreds of thousands of smaller molecules

4. Four major groups of macromolecules 1. Carbohydrates (monosaccharide) -compounds made up of carbon, hydrogen, & oxygen atoms. Living things need these for energy. Foods: pasta, bread, fruits Ex: glucose, lactose, fructose.

6. 2. Protein (amino acid) -regulates cell processes, helps fight diseases, gives structural support. Ex: meats, peanut butter, egg whites, beans, nuts Found in hemoglobin, enzymes

8. 3. Lipids (glycerol, fatty acids) -stores energy-long term, insulation, layer of protection Ex: oils, butter Found in: steroids, wax paper, cholesterol

10. 4. Nucleic Acids (nucleotides) -RNA/DNA (heredity information) Found in steak, salad (foods)
