Question

question 1 - 6
the diagram below shows three repeating units of a polymer.
which of the following molecular structures make up the repeating units shown in the diagram?

• fatty acid
• nucleotide
• amino acid
• monosaccharide

Explanation:

The repeating units in the diagram have multiple - OH groups and a ring - like structure typical of monosaccharides. Fatty acids have a long - chain hydrocarbon with a carboxyl group, nucleotides have a sugar, a phosphate, and a nitrogenous base, and amino acids have an amino group, a carboxyl group, and a side - chain. Monosaccharides are the building blocks of polysaccharides and have the general formula (CH₂O)ₙ. The structure shown has the characteristic features of monosaccharides.

Answer:

monosaccharide
