Lipid functions

• Water Source:

  • When lipids are chemically broken down, water is released through that reaction acting as a water source
• Protection:

  • To protect organs such as the heart and kidneys there is a layer of fat that surrounds them
• Insulation:

  • The fat that is stored underneath the skin and it acts as an insulator against body heat and provides warmth
• Absorption:

  • Vitamins A and D dissolve in fats. They can also be absorbed into the intestines
• Buoyancy:

  • The fat stored in the animal gives the animal buoyancy and warmth
• Structure:

  • Fats (phospholipids) form part of all membranes
• Energy:

  • Fat is stored in plant seeds which can be used for energy in the future
• Waterproofing:

  • Waxes are able to waterproof plant and animal cuticles because they are a type of lipid.
