Question

Which one of the following structural formulae of two organic compounds is correctly identified along with its related function?

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

Answer 1

The correct option is A A:Lecithin -a component of cell membrane

Lecithin is a phospholipid composed of choline and inositol. It is found in all living organisms as a major component of the cell membrane.
the molecule b is adenine, one of the two purine nucleobases (the other being guanine) used in forming nucleotides of the nucleic acids.
