Which one of the following biomolecules is correctly characterised?

  1. A
    Alanine amino acid – Contains an amino group and an acidic group anywhere in the molecule
  2. B
    Lecithin – a phosphorylated glyceride found in cell membrane
  3. C
    Palmitic acid – an unsaturated fatty acid with carbon atoms
  4. D
    Adenylic acid – adenosine with a glucose phosphate molecule

Solution & Step-by-step Explanation

* Lecithin is a phospholipid (phosphorylated glyceride) and a major component of biological membranes.Alanine is an -amino acid (amino and acid groups on the same carbon).Palmitic acid is saturated with carbons.Adenylic acid is a nucleotide (adenosine + phosphate).
