Standard Text: Select all that apply.
1. Triglycerides
2. Phospholipids
3. Steroids
4. Lecithins
5. Bile acids

Question 2

Cholesterol, triglycerides, and phospholipids travel between the liver and peripheral tissues through which mechanism?

Answer to Question 1

Correct Answer: 1,2,3
Rationale 1: Triglycerides are the most common classifications of lipids.
Rationale 2: Phospholipids are a class of lipids essential to building plasma membranes.
Rationale 3: Steroids are a diverse classification of lipids.
Rationale 4: Lecithins are not a classification of lipids. Lecithin is the best-known phospholipid.
Rationale 5: Bile acids are not a classification of lipids. Cholesterol is a building block of bile acids.
Global Rationale: Triglycerides are the most common classifications of lipids. Phospholipids are a class of lipids essential to building plasma membranes. Steriods are a diverse classification of lipids. Lecithins are not a classification of lipids. Lecithin is the best-known phospholipid. Bile acids are not a classification of lipids. Cholesterol is a building block of bile acids.

Answer to Question 2

Correct Answer: 1
Rationale 1: Apoproteins are specific for cholesterol, triglycerides, and phospholipids, and they act as carrier molecules for transporting these lipids through the blood.
Rationale 2: Lipid molecules are not soluble in plasma and so require protein binding for transport.
Rationale 3: Albumin is the most common plasma protein, but it is not specific as a carrier for cholesterol, triglycerides, and phospholipids.
Rationale 4: Lipoprotein molecules that combine lipids with a carrier protein contain different amounts of cholesterol, triglycerides, and phospholipids.
