Question

the models show the chemical structures of a fatty acid and a nucleotide. complete the table to compare these structures. fatty acid nucleotide is a building block of triglycerides contains nitrogen has a nitrogenous base

Explanation:

Step1: Recall triglyceride composition

Triglycerides are composed of glycerol and fatty - acids. So, fatty acids are building blocks of triglycerides, while nucleotides are not.

Step2: Analyze nitrogen content

The fatty - acid structure shown does not contain nitrogen atoms. The nucleotide structure has nitrogen in its nitrogenous base part.

Step3: Identify nitrogenous base

Fatty acids do not have nitrogenous bases. Nucleotides have a nitrogenous base as part of their structure.

	Fatty acid	Nucleotide
Contains nitrogen	No	Yes
Has a nitrogenous base	No	Yes

Answer:

	Fatty acid	Nucleotide
Contains nitrogen	No	Yes
Has a nitrogenous base	No	Yes
