Lipids

Front

What are the characteristics of saturated fatty acids?

Back

Saturated fatty acids have single bonds, are straight in structure, and are solid at room temperature.

Front

What elements make up lipids?

Back

Lipids are primarily composed of Carbon, Hydrogen, Oxygen, and sometimes Phosphorus.

Front

What does hydrophobic mean?

Back

Hydrophobic literally means 'afraid of water'.

Front

What state are unsaturated fats in at room temperature?

Back

Unsaturated fats are liquids at room temperature.

Front

What type of fats tend to be solid at room temperature like butter?

Back

Saturated fats tend to be solid at room temperature.

Front

What is the difference between saturated and unsaturated fatty acids?

Back

Saturated fatty acids have no double bonds between carbon atoms, while unsaturated fatty acids have one or more double bonds.

Front

What is the role of phospholipids in cell membranes?

Back

Phospholipids form the bilayer of cell membranes, providing structure and regulating the movement of substances in and out of the cell.

Front

What are triglycerides and their function?

Back

Triglycerides are a type of lipid made of glycerol and three fatty acids; they store energy and provide insulation.

Front

What is the significance of the double bonds in unsaturated fats?

Back

Double bonds in unsaturated fats create kinks in the fatty acid chains, preventing them from packing tightly together, which keeps them liquid at room temperature.

Front

How do lipids differ from carbohydrates in terms of energy storage?

Back

Lipids store more energy per gram than carbohydrates due to their higher hydrogen content.
