GS Lipids Review (17 Q)

Front

What are saturated lipids?

Back

Saturated lipids are types of lipids that have as many hydrogen atoms as possible and contain only single bonds in the fatty acid chain.

Front

What type of fats are found in olive oil?

Back

Olive oil contains unsaturated fats.

Front

What are the primary functions of lipids?

Back

The primary functions of lipids include energy storage, insulation, and serving as structural components of cell membranes.

Front

What type of lipid is characterized by having double bonds in its fatty acid chains?

Back

Unsaturated fats are characterized by having one or more double bonds in their fatty acid chains.

Front

What is a triglyceride?

Back

A triglyceride is a type of lipid formed from one glycerol molecule and three fatty acids.

Front

How do saturated fats differ from unsaturated fats in terms of their structure?

Back

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

Front

What is the significance of the double bond in unsaturated fatty acids?

Back

The double bond in unsaturated fatty acids creates kinks in the fatty acid chain, preventing the molecules from packing tightly together, which affects their physical state at room temperature.

Front

What are trans fats and how are they formed?

Back

Trans fats are a type of unsaturated fat that has been hydrogenated to make them more solid at room temperature, often found in processed foods.

Front

What is the role of lipids in cell membranes?

Back

Lipids, particularly phospholipids, form the structural foundation of cell membranes, creating a barrier that separates the interior of the cell from the external environment.

Front

What is the difference between essential and non-essential fatty acids?

Back

Essential fatty acids cannot be synthesized by the body and must be obtained from the diet, while non-essential fatty acids can be produced by the body.
