Lesson 7: Lipids Flashcards
Are lipids soluble in water?
No they are hydrophobic water fearing.
When are lipids soluble
Lipids are soluble in hydrophobic solvents.
What is the phospholipid layer called?
Phospholipid bilayer.
What are lipids primarily composed of?
Lipids are primarily composed of carbon, hydrogen, and oxygen.
True or False: Lipids are soluble in water.
False: Lipids are generally insoluble in water.
Fill in the blank: The main types of lipids include __________, phospholipids, and steroids.
triglycerides
What is the primary function of triglycerides?
The primary function of triglycerides is to store energy.
Which type of lipid forms the bilayer of cell membranes?
Phospholipids form the bilayer of cell membranes.
Multiple Choice: Which of the following is a function of steroids? A) Energy storage B) Hormone production C) Insulation D) All of the above
B) Hormone production
What is a key characteristic of saturated fats?
Saturated fats have no double bonds between carbon atoms.
True or False: Unsaturated fats are liquid at room temperature.
True
What are essential fatty acids?
Essential fatty acids are fatty acids that must be obtained through diet because the body cannot synthesize them.
Hydrophilic vs Hydrophobic
Hydrophilic: Water Loving (Phospholipids have a phosphate head that is water loving)
Hydrophobic: Water fearing (Phospholipids have 2 tails that are non polar and water loving)
