Lipids Flashcards
Lipids
-long term energy storage stored as fat
-makes up cell membranes and endoplasmic reticulum
the main biological functions of lipids include storing energy
atoms found in lipids
carbon, hydrogen and oxygen
1:2: less than one
Triglycerides
Used as energy storage molecules.
store unused calories and provide your body with energy
Things in Triglycerides
Carbon, Hydrogen, Oxygen
glycerol and three fatty acids
Saturated vs Unsaturated fats (structural and physical property differences)
Saturated fatty acids lack double bonds between the individual carbon atoms, while in unsaturated fatty acids there is at least one double bond in the fatty acid chain. Saturated fats tend to be solid at room temperature and from animal sources, while unsaturated fats are usually liquid and from plant sources.
Phospholipids: where are they found in cells?
are major membrane lipids that consist of lipid bilayers. They are found in cell membranes
Importance of hydrophilic heads and hydrophobic tails
The hydrophilic heads attract water into the membrane and are then propelled away by the hydrophobic tails.
