When proteins are broken down, they are mainly converted into amino acids , which are small organic molecules that are the building blocks of proteins. These amino acids are the key chemical products of protein digestion and decomposition in the body.

What chemical is formed?

  • Proteins are long chains of amino acids linked by peptide bonds.
  • During digestion or other breakdown processes (proteolysis), these peptide bonds are hydrolyzed, and the protein is split into individual amino acids.
  • So, the type of chemical formed when proteins are broken down is amino acids.

Extra context (quick)

  • This breakdown process is called proteolysis and is a form of hydrolysis reaction, because water is used to break the peptide bonds.
  • The body then uses these amino acids to build new proteins, make enzymes and hormones, or further catabolize them for energy when needed.
