 What elements make up lipids? Lipids are large biomolecules that are made mostly of carbon and hydrogen with small amounts of oxygen.

 Name some examples of lipids. Fats Oil Waxes Steroids

Describe the composition of a glycerol molecule. A glycerol is a 3 carbon molecule that serves as a backbone for a lipid molecule. Attached to the glycerol are 3 fatty acid groups. C CH2CH2CH2CH2CH2

H H H H H H C C C C C H  Define fatty acid. A fatty acid is a long chain of carbon and hydrogen. H H H H H H C C C C C H

 Fatty acids H H H H H H C C C C C H If each carbon in the chain is bonded to other carbons by single bonds….the fatty acid is said to be saturated. H H H H H H C C C C C H Meats Dairy Products Butter

 Fatty acids H H H H H C C C C C H H H H H If a double bond is present in the chain, the fatty acid is unsaturated. H H H H H C C C C C H H H H H Vegetable oils Peanut butter

 Explain why lipids cannot dissolve in water solutions? Lipids are insoluble in water because their molecules are nonpolar and are not attracted to water.  Define nonpolar ► Equal distribution of charges (same charge) Lipid H20 + - + +

 Lipids Hydrophilic (Loves H20) Phospholipid Bilayer Hydrophobic (Hates H20)

Functions of Lipids ☻ Are the major components of the membranes that surround all living cells ► Structural Support  Cells use lipids for energy storage  Insulation  Protective Coverings
