  1. A
    A : Lecithin - a component of cell membrane
  2. B
    B : Adenine - a nucleotide that makes up nucleic acids
  3. C
    A : Triglyceride - major source of energy
  4. D
    B : Uracil - a component of DNA

Solution & Step-by-step Explanation

Structure A is Lecithin, which is a phospholipid found in cell membranes. Structure B is Adenine, which is a nitrogenous base (purine). Adenine is not a nucleotide (it lacks sugar and phosphate) and is found in both DNA and RNA. Uracil is found only in RNA.
