Lipids Flashcards
What elements do lipids contain?
Lipids contain carbon (C), hydrogen (H), and oxygen (O) with a ratio of hydrogen to oxygen always bigger than 2:1.
What is an example of a lipid?
Lauric acid (C12H24O2) is a fat found in coconuts.
What are some examples of lipid compounds?
Examples of lipid compounds include triglycerides, steroids, and fat-soluble vitamins.
Why do lipids contain lots of energy?
Lipids contain high energy bonds, providing more energy than carbohydrates.
What is the monomer of lipids?
The monomer of lipids is glycerol combined with 3 fatty acids.
What is the importance of lipids?
Lipids serve as a reserve energy source, provide heat insulation, are a main component of cell membranes, and more.
How do lipids assist desert animals?
Lipids provide a source of water for desert animals, as breaking ester bonds releases water.
What role do lipids play in plants?
Lipids form waterproof waxy layers and waxy cuticles to prevent water loss in some plants.
What are unsaturated fats typically found in?
Unsaturated fats are usually found in plants and oily fish.
What are examples of unsaturated fats?
Examples of unsaturated fats include sunflower oil, castor oil, and avocados.
What characterizes unsaturated fatty acids?
Unsaturated fatty acids have one or more double bonds and are liquid at room temperature.
Where are saturated fats commonly found?
Saturated fats are found in animal products.
What is the structure of saturated fatty acids?
Saturated fatty acids have 2 hydrogen atoms bonded to each carbon with no double bonds.
Why are saturated fats considered less healthy?
Saturated fats should be eaten in moderation as they can lead to cholesterol build-up and atherosclerosis.
What health issues can arise from excessive saturated fat consumption?
Excessive consumption can lead to high blood pressure, heart disease, heart attacks, and stroke.
