Introduction • A diverse group of water-insoluble (hydrophobic) compounds • three types of lipids—storage or structural lipids, “bioactive” lipids
Lipid basics: Fatty acids Fats and oils--made of fatty acids Fatty acids--long chain hydrocarbon derivatives. Low oxidative state. excellent source of energy
Lipid basics: Fatty acids • Fats and oils—made of fatty acids • Fatty acids—long chain hydrocarbon derivatives. Low oxidative state, excellent source of energy
Fatty acids Carboxylic acids with hydrocarbon chains of 4 to 36 carbons long( C4 to C36) Both saturated and unsaturated(double bonded) Unbranched, branched(methyl group), or three carbon rings
Fatty acids • Carboxylic acids with hydrocarbon chains of 4 to 36 carbons long (C4 to C36) • Both saturated and unsaturated (double bonded) • Unbranched, branched (methyl group), or three carbon rings
