  • Lipids
    • type
      • signaling
        • sterols, cofactor pigments
          • phosphatdylinstol = c fam in membrane
            • broken down to ip3 which binds to ionotropic receptors
              • release of CA from SA
              • also in neurones - CA for NT relase
          • insulin
            • binds to receptors and activates IRS
              • recruits pi3k leads vesicles to membrane
        • Eicosanoid
          • cholesterol = starting Mol
            • arachindonca
              • protaglyndins and thromboxane and leukotryins
                • proteo = vasodialation
                  • increases temp to help fight infection
                  • effects blood flow
                • thromboxane = blood clotting
                • leukotrine
                  • contraction of smooth muscle
          • steroid hormones
            • cortisol
              • released in response to stress, increases gluconeogensis
            • corticosterone
              • intermed in production of aldosterone
            • progesterone
              • oesterogen = most stable = more double bond
        • vitamens
          • water sol = B AND C
          • insol = K,E,D,A
            • D = d7chol- UV light breaks bonds = D3
            • A= b-caratine = precusor
              • cleavage = A1 - Vis light = CIS to TRANs bond
      • storage
        • fats Oils
          • = energy stroage
          • waxes -esters of long chain FA and long chain OH
        • PUFAs
          • omega 3 - diff naming system - name from double bond
        • physical properties
          • increase unsaturation = increase solubility
          • also decrease melting point
        • triglycerides
          • fuel stored in adipose = most are mixed FA chains
          • energy from fats = more eff then glucose 108 ATP from full oxidation
            • hydrophobic = lighter
              • partial hydrogenation
        • cis to trans bond = CVD
      • structure
        • Glycerophopholipids
          • x2 FA, glycerol, p diester
          • naming =Phosophtyl OH group
          • any charge heads + found in membranes
        • Galactolipids
          • sugar head= polar head with OH
        • sphingolipids
          • no glycerol
          • hydrocarbon- =VDF forces with x2 FA non polar chain
          • sphingomyclies
            • polar head found in membranes
        • gangcosphingolipids
          • Polar head = one or more sugars ? Cerebrosides = one sugar ?
          • Galactose – plasma membrane of neuronal tissue ? Glucose – plasma membrane of non-neuronal tissue
        • Gangliosides
          • sterols
            • 4 hydrocarbon rings
            • ridgid
            • cholesterol
              • maintains membrane fluidity seperates Phosholipids
              • prevents crystalisation
    • Synthesis and breakdown
      • synth
      • breakdown
