Saturated Fatty Acid BUILD Omega3 cismonounsaturated Fatty Acid

Saturated Fatty Acid BUILD!!! Omega-3 -cis-monounsaturated Fatty Acid

Phospholipid Bilayer of Cell Membrane

• What is similar about all of these structures? • What is different?

Lipid Learning Targets • Fatty Acids can be saturated, monounsaturated, or polyunsaturated • Unsaturated fatty acids can be cis or trans isomers • Triglycerides are formed by condensation from three fatty acids and one glycerol

There are many classes of lipids. The ones to know are fats, waxes, sterols, and phospholipids. The main function of most lipids is energy storage. Some lipids are also used for structure (eg. phospholipids) or for signaling (eg. testosterone).

Why are they called “Fatty Acids? ” Which part makes them an acid? Lipids Types of Fatty Acids Note: you should be able to draw a saturated fatty acid Which part makes them “fatty”? Saturated Mono-unsaturated Poly-unsaturated #Must. Memorize

cis-fats are good fats, trans-fats are bad fats cis-fatty acid Liquid at room temperature Trans-fatty acid Solid at room temperature

The cheer! Fatty acid? Oh just wait I’ll C C Carboxyl Unsaturated’s cis or trans One’s bent one’s straight look at your hands

Lets build some fatty acids! Table 1 - 8 carbon saturated fatty acid Table 2 - 8 carbon cis-monounsaturated omega 3 fatty acid Table 3 - 8 carbon trans-monounsaturated omega 3 fatty acid Table 4 - 8 carbon cis-monounsaturated omega 3 fatty acid Table 5 - 8 carbon saturated fatty acid Table 6 - 8 carbon cis-monounsaturated omega 3 fatty acid Table 7 - 8 carbon trans-monounsaturated omega 3 fatty acid Table 8 - 8 carbon trans-monounsaturated omega 3 fatty acid

glycerol Learning target three fatty acids Triglyceride

Construct a glycerol

Now build a triglyceride!
