Q. Which one of the following biomolecules is correctly characterised ?
A) Lecithin – a phosphorylated glyceride found in cell membrane
B) Palmitic acid – an unsaturated fatty acid with 18 carbon atoms
C) Adenylic acid – adenosine with a glucose phosphate molecule
D) Alanine amino acid – contains an amino group and an acidic group anywhere in the molecule
Explanation
[Solution from source] Lecithin is a phospholipid, a glyceride carrying a phosphate group, and it is a major part of cell membranes. Palmitic acid is a saturated 16-carbon fatty acid, and adenylic acid contains ribose, not glucose. Answer (1).
