  • Definitions
  1. Triglyceride
    1. Lipid composed of three molecules of Fatty Acid esterified to Glycerol
    2. Triglycerides are a non-polar fat synthesized from Carbohydrates or ingested
    3. Triglycerides are High Energy Molecules that are stored for later use in animal adipose cells (fat cells)
  2. Diglyceride
    1. Lipid composed of two Fatty Acid chains esterified to Glycerol
  3. Monoglyceride
    1. Lipid composed of a single Fatty Acid chain esterified to Glycerol
  4. Phosphoglyceride
    1. Diglyceride with the one free OH group on Glycerol attached to a phosphate (Phosphatidate)
    2. Phosphate in turn is attached to Serine, Ethanolamine, Choline or Inositol
    3. Includes Phosphatidyl Serine, Phosphatidyl Ethanolamine, Phosphatidyl Choline, Phosphatidyl Inositol
