Tertiary Structure

The three-dimensional shape of a protein molecule determined by interactions among its amino acids' side chains, beyond simple folding.

H-Bonds

Hydrogen bonds, a type of weak chemical bond that occurs when a hydrogen atom covalently bonded to one electronegative atom is also attracted to another electronegative atom.

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.
