• Saturated fats


  Single bonds between neighboring carbons in the hydrocarbon chain, hydrogen atoms attached to the carbon skeleton is maximized
• Saturated fats


  • Animal fats with stearic acid and palmitic acid contained in meat
• Unsaturated fats


  Hydrocarbon chain that contains a double bond, liquid at room temperature and are called oils
• Monounsaturated fats


  One double bond in the molecule
• Monounsaturated fats


  • Olive oil
• Polyunsaturated fats


  More than one double bond in the molecule
• Polyunsaturated fats


  • Canola oil
• Lipids


  A wide variety of biomolecules including fats, oils, waxes and steroid hormones
• Lipids


  • They do not dissolve in water; they are hydrophobic
  • They are composed primarily of carbon, hydrogen, oxygen, phosphorus and sulfur (lipids also contain nitrogen in some cases)
• Fats


  A good source of stored energy
• Oils and waxes


  Used to form protective layers on our skin, preventing infection
• Steroid hormones


  Important regulators of cell activity
• Steroid hormones such as estrogen

  Have been implicated in cancers of the female reproductive system
• Saturated fats


  Single bonds between neighboring carbons in the hydrocarbon chain, with the carbon skeleton maximized with hydrogen atoms
• Saturated fats


  • Animal fats with stearic acid and palmitic acid contained in meat
• Unsaturated fats


  The hydrocarbon chain contains a double bond, these fats are liquid at room temperature and are called oils
• Monounsaturated fats


  Have one double bond in the molecule, e.g. olive oil
• Polyunsaturated fats


  Have more than one double bond, e.g. canola oil
• Phospholipids


  The major constituent of the plasma membrane, composed of fatty acid chains attached to a glycerol or similar backbone, with both hydrophobic and hydrophilic regions
• Steroids


  Have a ring structure, are hydrophobic, and include cholesterol which is a key component of animal cell plasma membranes
• Waxes


  Made up of a hydrocarbon chain with an alcohol (-OH) group and a fatty acid, examples include beeswax, lanolin, and plant leaf coatings
