    • linoleic from polyunsaturated vegetable oils
    • linolenic from milk soybeans flaxseed oil
  8. lipoproteins structure and function
    • combination fat and protein
    • wrap insouable fat in water soluable protein for transport in blood
  9. LDL Low density lipoproteins
    carry fat and cholesterol to cells

    • energy
    • essential nutrients

    • hardened relative to polyunsaturateds

    molecular shape alter due to hydrogenation process
  15. Invisible fat sources

    • cream
    • egg yolk
