LIPID (FAT) NOTES
Lipids
Waxy or oily compounds that store energy in their bonds
Elements in lipids – carbon, hydrogen & oxygen
Examples – fats, oils & waxes
Functions in the body
**Long-term energy storage**InsulationForms the protective membrane
that surrounds each cellSome used as chemical
messengers
Types of Lipids
Saturated – fats that hold all the hydrogen that molecule can holdExamples: shortening & butter
H H H
H – C – C – C – O – H
H H H
Types of Lipids, cont.
Unsaturated – fats that have some spaces left in the molecule for hydrogenExamples: oils
H
C = C = C – O – H
H H
Building Blocks
Fatty acids – the building blocks of fats (lipids)
Foods/Words that Indicate Lipids: Fats Oils Waxes Cottonseed oil, Palm oil, Soybean oil, Vegetable oil, Corn
oil, Canola oil, etc. Vegetable Shortening Cholesterol Butter Animal Fat (Lard) Dairy Products (Milk, Cheese, Buttermilk, Cream etc.) Nuts (Peanuts, Almonds, etc.) Meat (Chicken, Pork, Beef, Bacon, etc.) Eggs (whole or yolks – not whites)
