Which one of the following biomolecules is correctly characterized?

Options

(a) Lecithin – A phosphorylated glyceride found in cell membrane
(b) Palmitic acid – An unsaturated fatty acid with 18 carbon atoms.
(c) Adenylic acid – Adenosine with a glucose phosphate molecule.
(d) Alanine amino acid – Contains an amino group and an acidic group anywhere in the molecule

Correct Answer:

Lecithin – A phosphorylated glyceride found in cell membrane

Explanation:

Palmitic acid is one of the most common saturated fatty acids found in animals and plants. It has 16 carbons including the carboxyl carbon. Adenylic acid is the nucleotide consisting of adenine, ribose or deoxyribose, and a phosphate group. It is a constituent of DNA or RNA. It is also called adenosine monophosphate. Amino acids are organic acids (with carboxylic group COOH) having amino group (-NH₂) generally attached to Carbon or carbon next to carboxylic group. The carbon also bears a variable alkyl group (R) or hydrogen or hydrocarbon. In alanine is represented by methyl group.
