Examples Fats Oils Waxes Steroids
Functions Long-term energy storage Main component of cell membranes Hormones Insulation/cushioning
Structure Long chains of carbon (and hydrogen) Two primary molecules: Glycerol Fatty Acids
Glycerol A simple 3-carbon alcohol
Saturated vs Unsaturated
Saturated Fatty acids Saturated fatty acids have the maximum number of hydrogen Known as FATS Generally found in animal sources Solids at room temperature
Unsaturated Fatty Acids Have two or more hydrogen replaced with double- bonds Known as OILS Generally found from plant sources Liquid at room temperature
Cis- vs Trans- Fatty acids
Cis- vs Trans- fatty acids Cis-fatty acids have the carbon on the same side of the double-bond Trans-fatty acids have carbons on different sides of the double bond Cis-fatty acids produce a bend in the molecule
Cis- vs Trans- Fatty acids
Degrees of Saturation
Polyunsaturated Fats Have more than one double bond
One glycerol + 3 Fatty Acids Triglyceride Can have 3 different fatty acids hydrophobic
Phospholipids Consist of glycerol, two fatty acids and one phosphate group
Phospholipids Are amphiphilic Make up cell membranes
Steroids Consist of a four-carbon ring Basis for many hormones
Lipids: Fats & Oils & Wax & Steroid
Biochemistry Part V Lipids. Lipids A class of organic molecules that are insoluble in water A class of organic molecules that are insoluble in water There.
Five Sense Biochemistry
Lipids Highly diverse structures Unifying property Hydrophobic: little to no affinity to water Contains hydrocarbons, which form nonpolar covalent bonds.
AP Biology Lipids: Fats & Oils AP Biology Lipids energy storage.
Notes Chapter 5 p.2 : Lipids
Which are made of which contain Which are made of which contain CarbohydratesFats/ oils Nucleic acids (e.g., DNA/RNA) Proteins Simple sugars (e.g., glucose)

Chapter 5 Section 3 Lipids Mrs. Kerstetter Biology.
AP Biology Intro to Organic Molecules & Lipids AP Biology Life is based on Carbon Carbon atoms are versatile building blocks Special bonding properties.
LIPID REVIEW Dr. E. Lipids A. Hydrophobic B. Hydrophillic C. Nonpolar D. Polar E. Both A & C F. Both A and C.
Lipid Review What are the four examples of lipids? 2.
Lipids: Fats & Oils Lipids Large biomolecules that are made mostly of carbon and hydrogen with a small amount of oxygen (sometimes.
Insoluble Biological Molecules
Fats and Lipids.
Lipids Fats, Oils and Other Things. Lipid Basics Made of C,H,O monomer = glycerol + fatty acids hydrophobic - don’t dissolve in water oil and.
LIPIDS Lipids are hydrophobic molecules composed of C, O, and H. In general, they contain fewer O-H bonds and more C-H bonds than carbohydrates do. If.
