2.3 Carbon Compounds
Carbon has 4 valence electrons so they are strong covalent bonds with many other elements including itself
Carbon-carbon bonds
The Chemistry of Carbon
Macromolecules (giant molecules)
Made from thousands or hundreds of thousands of smaller molecules
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.
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
3. Lipids (glycerol, fatty acids)
-stores energy-long term, insulation, layer of protection
Ex: oils, butter
Found in: steroids, wax paper, cholesterol
4. Nucleic Acids (nucleotides)-RNA/DNA (heredity information)
Found in steak, salad (foods)
1. Color each organ a different color
2. Cut, glue, & label organs (ONE AT A TIME) to correct locations
3. On back of body, write the functions of organs:Mouth large intestineEsophagus liverStomach pancreasSmall intestine gall bladder
