Question

part a proteins are polymers of ______. glycerol amino acids \\(\ce{ch2o}\\) units hydrocarbons nucleotides

Explanation:

To determine the monomer of proteins, we recall biological macromolecule structure: proteins are polymers made by linking amino acids via peptide bonds. Glycerol is part of lipids (triglycerides), \( \text{CH}_2\text{O} \) units relate to carbohydrates, hydrocarbons are simple carbon - hydrogen compounds, and nucleotides are monomers of nucleic acids. So amino acids are the correct monomer for proteins.

Answer:

The correct option is the one with "amino acids" (the option labeled with "amino acids" among the given choices).
