Monomers are the building blocks of which of the following? SELECT ALL THAT APPLY
kirill [66]

Monomers are molecules whose linkage between them form polymers.

<h3>What are monomers?</h3>

Monomers are molecules that have a low molecular mass.

<h3>Characteristics of monomers</h3>

  • When many monomers come together through chemical bonds they form a polymer, which is a macromolecule.

  • Natural monomers allow the formation of biomolecules found in living beings.

  • Carbohydrates, for example, are macromolecules that are created from the bond established by monosaccharides (monomers).

Therefore, we can conclude that polymers, in short, are chains of monomers -generally joined by covalent bonds-.
