• LIPIDS

  a group of macromolecules that stores energy, signals between cells, and forms the cell membrane
• LIPID BUILDING BLOCKS = FATTY ACIDS
• LIPIDS = INSOLUBLE IN WATER ; NON POLAR
• SATURATED

  • straight carbon chains because they only contain single carbon-carbon bonds
  • SOLID at room temp ANIIMAL fats
• UNSATURATED

  • a kink in their chain caused by a double bond or even a triple bond between carbons
  • LIQUID at room temp PLANT
• FATTY ACID = hydrocarbon chains of both saturated and unsaturated fats are attached to a carboxylic acid functional group
• LIPIDS = store TRIGLYCERIDES
