Question

The phospholipids or phosphoglycerides are modifications of triacylglycerols where phosphate groups are typically found in the:

• A. sn-1 position
• B. sn-2 position
• C. sn-3 position
• D. sn-1 or 2 position

Hint:

Phospholipids: phosphate at sn-3.
Fatty acids at sn-1 and sn-2.
Glycerophospholipids structure.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Phospholipids are derived from triacylglycerols.
The phosphate group is attached at a specific position.
Step 2: Key Formula or Approach:
No specific formula.
Need to know the structure of phospholipids.
Step 3: Detailed Explanation:
In phospholipids, the phosphate group is typically at the sn-3 position.
Fatty acids are at sn-1 and sn-2 positions.
Thus, the phosphate group is at sn-3.
Step 4: Final Answer:
The phosphate group is at the sn-3 position.
Hence, the correct option is (C). \bigskip
