Question

Which biomolecule is correctly characteristed?

• A. Lecithin phosphorylated glyceride found in cell membrane
• B. Palmitic acid unsaturated fatty acid with 18 carbon atoms
• C. Adenylic acid adenosine with glucose phosphate molecule
• D. Alanine amino acid contains an amino acid and an acidic group anywhere in the molecule.

Answer 1

The correct option is A Lecithin phosphorylated glyceride found in cell membrane

Lecithin is a phosphorylated glyceride. It is a phospholipid with glycerol, fatty acids ,a phosphate group and choline. It is found in the cell membrane. Palmitic acid is a saturated fatty acid with 16 carbon atoms. Adenylic acid is also called as Adenosine monophosphate (AMP). It is an adenosine with a phosphate group and the ribose sugar. It is an ester of phosphoric acid and the adenosine. Alanine is a neutral amino acid. It contains one amino group and one carboxylic group.

Thus, the correct answer is option A.
