  • FUNCTIONS OF LIPIDSLIPIDS
  • 1. Energy storage View slide
  • Lipids or Glucose for Energy?H3CCH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2CH2COOHHCCHHCCHCHCH2OHOHOHOOHHO More reduced state (more H bound to C) More potential for oxidationLess reduced state (more O bound to C) Less potential for oxidation View slide
  • 2. Thermal insulation
  • Mechanical protection
  • Platelet-activatingfactor (PAF) is apotent mediatorthat occurs at verylow concentrationsin cells and tissues
  • Sleep Induction
  • : Isoprene unit.
  • Biological functions:COO-arachadonic acid
  • Biological Processes Regulated byEicosanoids
  • •Lipid rafts are plasma membranemicrodomains rich in cholesterol andsphingolipids.•important for neuronal celladhesion, axon guidance and synaptictransmission.•crucial for neural development andfunction.
  • Structural support
  • Function as antibacterial
  • Precursor
  • While plant oils such as cotton, coconut,palm, castor beans, soy, andsunflowers are also natural sources ofstearic acid,Soap making. deodorants foundationcreams, hand lotions, hair straighteningproducts, and shaving creams.
  • Biodiesel is a clean-burning fuel producedfrom plant lipids such as soybean oil and willbe a good source of feul in near future.Lubricantspalm, sunflower, soybean oils are used tomake industrial bio-lubricants. engineoil, grease and metalworking fluids.
