A. Protein is a polymer of amino acids linked by peptide bonds.
B. Unsaturated fatty acids are a type of fats containing a high proportion of fatty acid molecules with at least one double bond (C=C double bonds).
C. Nucleic acids are polymers of nucleotides. Each nucleotide is linked to its adjacent one by phosphodiester
linkages.
D. Polysaccharides are polymers of sugars. The monosaccharide units are linked by glycosidic bonds.
