Q1 QUESTION 1 OF 28
Glycerol contains how many carbon atoms?
-3
-4
-5
- 15
CORRECT ANSWER
-3
Page 1
, RATIONALE
Glycerol, a triol compound, has three carbon atoms in its structure, specifically defined by its three hydroxyl (-OH) groups attached to each
carbon. This characteristic makes glycerol a key component in lipid metabolism and a building block for triglycerides.
Q2 QUESTION 2 OF 28
Which of the following are derived from or made from fatty acids?
- Cholesterol
- Carotenoids
- Phosphoglycerides
- Both A and B
- Both A and C
CORRECT ANSWER
- Phosphoglycerides
RATIONALE
Phosphoglycerides are formed from glycerol and two fatty acid chains, serving as key components of cell membranes and playing a critical
role in membrane fluidity and function. Cholesterol, while important in membrane structure, is a sterol derived from acetyl-CoA and not from
fatty acids.
Q3 QUESTION 3 OF 28
Triacylglycerols are made from a ________ and ________.
- glycerol; cholesterol Correct!
- glycerol; three fatty acids
- ceramide; three fatty acids
- ceramide; three cholesterols
- carotenoid; two cholesterols
CORRECT ANSWER
- glycerol; three fatty acids
RATIONALE
Triacylglycerols are formed through the esterification process of one glycerol molecule with three fatty acid chains, creating a highly efficient
energy storage form in adipose tissue. This biochemical structure highlights the significance of lipids in metabolic energy reserves and
cellular functions.
