Coolant / Evaporation - aids body cooling. 2. High specific heat - bodies of water stay constant temp. 3. Transport/Universal Solvent - polarity dissolves many substances. 4. Habitat: Major component of internal (organism) & external environments. 5. Cohesion supports animal weight. 6. Adhesion (capillary action) pulls water up plants. 7. Low density of ice - protects life beneath it. 1 - 100 3-100 1 - 100 3-100A Monosaccharides 3-200 1 - 100 3-200A Glucose Fructose Ribose Deoxyribose 3-300 1 - 100 3-300A Sucrose Lactose Maltose 3-400 1 - 100 3-400A Plant starch (Amylose) Glycogen Cellulose Chitin Pectin 3-500 1 - 100 3-500A 1) Energy source of all cells - Glucose 2) Energy storage (plants) - Starch (amylose) 3) Energy storage (animals) - Glycogen 4) Gelling agent - Pectin 5) Arthropod exoskeletons - Chitin 6) Cell walls of plants - Cellulose 1 - 100 4-100 1 - 100 4-100A 3 Fatty acids Glycerol 4-200 1 - 100 4-200A Saturated Fatty Acid 4-300 1 - 100 4-300A Phospholipids 4-400 1 - 100 4-400A Testosterone Estrogen Cholesterol Progesterone Chortisone 4-500 1 - 100 4-500A 1) Long-term energy storage - fats & oils 2) Water-proofing - waxes 3) Buoyancy - fats & oils 4) Chemical messengers - steroids 5) Lipid bilayers of cell membranes- Phospholipids 1 - 100 5-100 1 - 100 5-100A Amino Acids 5-200 1 - 100 5-200A Peptide Bond 5-300 1 - 100 5-300A Amino Group 5-400 1 - 100 5-400A Denaturation 5-500 1 - 100 5-500A 1) Enzyme catalysis - Amylase, Proteases or Pectinase 2) Body defense - Antibodies 3) Transport - Hemoglobin 4) Motion - Actin or Myosin 5) Structure/support - Collagen 6) Regulation/ communication Insulin or Adrenaline 6- 100 1 - 100 1 - 100 6-100A Catalyst 6-200 1 - 100 6-200A 1) Lower activation energy. 2) Flex or twist to break bonds. 3) Bring substrates together. 6-300 Noncompetitive Inhibition (Allosteric Inhibition) 1 - 100 6-300A 6-400 1 - 100 6-400A Competitive Inhibition 6-500 1 - 100 6-500A Temperature pH Enzyme Concentration Substrate Concentration
