Question

Which one of the following biomolecules is correctly characterised?

• A. Lecithin-Aphosphorylated 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

Answer 1

The correct option is A Lecithin-Aphosphorylated glyceride found in cell membrane

The only correct statement among the given options is about lecithin.
Lecithin is a major component in the lipid bilayers of cell membranes and is also found within brain nerve tissues.
Rest of the statements can be corrected as follows
- Alanine is a neutral amino acid with no-cyclic hydrocarbon chain, one amino group, and one carboxyl group.
- Palmitic acid is a saturated fatty acid
- Adenylic acid has pentose sugar in it not glucose
