1. Chapter 15 Waxes, Fats and Oils- Triglycerides

2. Waxes are esters made of one Fatty Acid and one long chain alcohol
Protective lipids found in the outer covers of
Plants: leaves/stem – prevent waterloss
Animals: waterproofing skin, fur and feathers
are esters
made of one Fatty Acid and one long chain alcohol

3. Fats and Oils Are Triglycerides/Triacylglycerols Esterification Rx of
1 Glycerol with 3 Fatty Acids
3 FA are a mix of saturated and unsaturated FA

4. Triglyceride Esterification
esterbond

5. Simple Naming of Fats
Name: Glycerol tristearate
Most detailed names we can do: trilaureate, - trimyristate, -tripalmitate

6. Fats are solids at RT Ex: fats in meat, butter, cheese
typically from an animal source
Contain a higher amount of saturated Fatty Acids
Called saturated fats

7. Oils are liquid at RT Ex: olive, canola, sunflower oil
typically from a plant source (seeds/nuts)
Contain a higher amount of cis-unsaturated/omega Fatty Acids
Called unsaturated oils

8. Solid vs liquid why? Saturated Fats have a higher MP/BP
they have higher Van de Waals
Unsaturated oils have kinks: lower
Van der Waals, lower MP/BP
