Lecithin is a phospholipid made up of the following ____.
(A). glycerol
(B). fatty acids
(C). phosphate group
(D). nitrogen compound
Choose the correct answer from the options given below:
(A). glycerol
(B). fatty acids
(C). phosphate group
(D). nitrogen compound
Choose the correct answer from the options given below:
Options
- A(A), (B) and (D) only.
- B(A), (B) and (C) only.
- C(A), (B), (C) and (D).
- D(B), (C) and (D) only.
Correct answer
C. (A), (B), (C) and (D).
Step-by-step solution
Lecithin is a type of phospholipid, specifically known as phosphatidylcholine, which is a major component of cell membranes.
Its structure consists of a glycerol backbone esterified with two fatty acid molecules at the first and second carbon positions.
The third carbon of the glycerol is esterified to a phosphate group.
The phosphate group is further attached to choline, which is a nitrogen-containing compound.
Thus, lecithin is composed of glycerol, fatty acids, a phosphate group, and a nitrogen compound.
All components (A), (B), (C), and (D) are present in lecithin.
Answer: (A), (B), (C) and (D).
