Question
Which one of the following biomolecules is correctly characterised?
-
Lecithin – A phosphorylated glyceride found in cell membrane
-
Palmitic acid – An unsaturated fatty acid with 18 carbon atoms
-
Adenylic acid – adenosine with a glucose phosphate molecule
-
Alanine amino acid – Contains an amino group and an acidic group anywhere in the molecule
Solution
A.
Lecithin – A phosphorylated glyceride found in cell membrane
Alanine is a neutral amino acid with non-cyclic hydrocarbon chain, one amino group and one carboxyl group. Palmitic acid is saturated fatty acid adenylic acid has pentose sugar in it not glucose.
