1. BiomoleculesForm = Function Review inquiry activity from previous class.
2. BIOMOLECULESMACROMOLECULESmade by polymerization-large compounds built by joining smaller ones together. Smaller units (subunits) are called monomers.4 major molecules important to life.Carbohydrates, lipids, nucleic acids and proteins.
3. BIO BUILDING BLOCKS
4. CARBOHYDRATES1:2:1 RATIO1 Carbon: 2 Hydrogen: 1 OxygenExample: the sugar glucose - C6H12O6Monomer – MonosaccharidePolymer - PolysaccharideMain source of energy for living thingsAlso has structural purpose for living things.Plant cells have cell walls made of celluloseAnimal cells store excess sugars as glycogen

8. CarbohydratePolymerMonomer(subunit)
9. LIPIDSMade of Carbon and Hydrogen NOT soluble in water (hydrophobic)doesn’t mix with waterUsed to store energy, as chemical messengers (hormones, steroids)Part of the cell membrane (phospholipids).Saturated-Solid at room temperature. No double bondsUnsaturated-liquid at room temperature. Double bonds between Carbons.
10. LIPIDS
11. LIPIDS - triglyceride
12. Phospholipids – cell membrane componentPhospholipids: fatty acids bound to glycerol, a phosphate group replaces one fatty acid.Phosphate group is hydrophilic—”water loving head”“Water fearing tails” are fatty acid chains—hydrophobic
13. LipidCell walls
14.
15. PROTEINSComposed of Nitrogen, Carbon, Hydrogen, and Oxygen.Monomers are called amino acidsControl rate of reactionsFunction in transport and formation of bone and muscle cells.Folded shape is important in enzyme recognition process.
16. ProteinsMonomersPolymers
17. PROTEINS –amino acids
18. NUCLEIC ACIDSComposed of Hydrogen, Oxygen, Nitrogen, Carbon and Phosphorus.Subunits (monomers) are called nucleotides. Store and transmit hereditary information.Ex. DNA , RNA
19. NUCLEIC ACIDS - nucleotides
20. Nucleic AcidsMonomerPolymer
21. NUCLEIC ACIDS RNA—ribose DNA—deoxyribose
