this molecule is a building block of which type of biomolecule? carbohydrate protein lipid nucleic acid

Explanation:

This molecule has a long - chain fatty acid structure with a carboxyl group at one end. Lipids are composed of fatty acids and glycerol. Fatty acids like this one are building blocks of lipids. Carbohydrates have a general formula of (CH₂O)ₙ and have a different structure. Proteins are made of amino acids with an amino and a carboxyl group and a variable side - chain. Nucleic acids are made of nucleotides with a sugar, a phosphate, and a nitrogenous base.

Answer:

C. lipid
