Peptide Backbone

The main structural component of a peptide, consisting of a repeated sequence of amino acids linked by peptide bonds.

Equilibrium

Equilibrium is a condition in a chemical reaction when the rate of the forward reaction equals the rate of the reverse reaction, leading to a constant concentration of reactants and products.

Tautomers
