List the different types of macromolecules of life, and for each one, list one of its functions and its main monomer.

What will be an ideal response?


There are 4 different types of macromolecules. One is carbohydrates, whose main monomer is a monosaccharide (or a glucose); its main function is energy storage. A second macromolecule type is lipids, whose main monomer is glycerol linked with several fatty acid tails; its function is also energy storage or insulation. A third is proteins, whose monomer is amino acids; proteins have many functions, including speeding reactions as enzymes. The last group of macromolecules is nucleic acids, whose monomer is a nucleotide; nucleic acids function to carry hereditary information.
