The Key Properties of Monomers

What type of bond connects monomers in macromolecules?

a covalent bond

What is a macromolecule?

a very large molecule made up of monomers

What is a monomer?

a chemical subunit used to create polymers

What is a polymer?

What are dehydration synthesis reactions?

Covalent bond is formed; the subcomponents of a water molecule (H and OH) being removed from interacting monomers

What are hydrolysis reactions?

Covalent bond is broken; the polymer is broken down into monomers

What monomer creates a carbohydrate?

a monosaccharide

What monomer creates a protein?

an amino acid

What monomer creates a nucleic acid?

a nucleotide

What monomer creates a lipid?

a fatty acid

What happens to the subcomponents of a water molecule during dehydration synthesis?

The H and OH join to form a water molecule

What happens to the subcomponents of a water molecule during hydrolysis?

A water molecule is broken down into subcomponents (H and OH) and each is added to a different monomer
