Question

the models show the chemical structures of a fatty acid and a monosaccharide. complete the table to compare these structures.

	fatty acid	monosaccharide
contains carbon
has carbon atoms arranged in a ring

Explanation:

Step1: Recall cellulose composition

Cellulose is a polysaccharide made of glucose (a monosaccharide) units. So, a fatty - acid is not a building block of cellulose, and a monosaccharide is.

Step2: Analyze carbon content

Both fatty acids and monosaccharides are organic compounds, so they both contain carbon.

Step3: Examine carbon - atom arrangement

The fatty - acid structure shown has a linear arrangement of carbon atoms, while the monosaccharide has carbon atoms arranged in a ring.

Answer:

	Fatty acid	Monosaccharide
Contains carbon	Yes	Yes
Has carbon atoms arranged in a ring	No	Yes
