R Groups Bonds Interact Substrate Suggest Amino Acids Involved

Amino acid R-groups interact with substrates, forming temporary bonds that strain substrate bonds and lower activation energy.

Amino acid R-groups interact with the substrate, forming temporary bonds that put strain on substrate bonds, thus lowering the activation energy.

Front Suggest how R-groups of amino acids are involved in catalysing reactions.
Back R-groups and enzymes:
  • R-groups interact with substrate also interact with substrate, forming temporary bonds
  • These bonds put strain on bonds within substrate which helps lower the activation energy
