What is the process of converting unsaturated fats to saturated fats by adding hydrogen?

What type of fatty acids have the maximum number of hydrogen atoms and no double bonds?

What class of organic compounds are lipids?

Why are lipids considered hydrophobic?

Which of the following is NOT a biologically important lipid?

What are fats also known as?

What is glycerol?

What does a fatty acid consist of?

How many fatty acids combine with one molecule of glycerol to form a fat?

In a fat molecule, how many hydroxyl groups are attached to glycerol?

What type of bonds do hydrocarbons in lipids form?

Which of the following is a derivative of fatty acids?

What is the main reason for lipids being insoluble in water?

Which of the following is a three-carbon alcohol?

True or false: Lipids are soluble in water but insoluble in organic solvents.

True or false: Fats are made from the combination of one molecule of glycerol with two fatty acids.

True or false: Glycerol is a four-carbon alcohol.

True or false: Phospholipids are the most biologically important lipids.

True or false: Steroids are not considered as biologically important lipids.

True or false: Fats consist of one molecule of glycerol with three fatty acids.

True or false: A fatty acid consists of a carboxyl group attached to a long carbon skeleton.

True or false: Hydrophobic molecules easily combine with water.

True or false: Unsaturated fats have the maximum number of hydrogen atoms and no double bonds.

True or false: A fat molecule consists of glycerol with three fatty acids.

True or false: Lipids are characterized by a carbon skeleton consisting of four fused rings.

True or false: Lipids are considered hydrophilic due to the presence of hydrocarbons.

Phospholipids are the major component of all cell membranes forming the phospholipid bilayer of the plasma membrane.

Cholesterol is not an important steroid and has no role in animal cell membranes.

Fats made from saturated fatty acids are called unsaturated fats or oils, and are liquid at room temperature.

Saturated fatty acids have the maximum number of hydrogen atoms possible and no double bonds.

Hydrogenation is the process of converting unsaturated fats to saturated fats by adding H.

Fats separate from water because water molecules form hydrogen bonds with each other and exclude the fats.

Phospholipids have hydrophobic tails and hydrophilic heads.

A diet rich in saturated fats may contribute to cardiovascular disease through plaque deposits (atherosclerosis).

Cholesterol is an essential component in animal cell membranes but high levels in the blood do not contribute to cardiovascular disease.

Fatty acids vary in length (number of carbons) and in the number and locations of double bonds.

The major functions of fats include energy storage, vitamin absorption, and cushioning of vital organs.

Steroids are lipids characterized by a carbon skeleton consisting of three fused rings.
