Forces That Drive Tertiary Structure. Most proteins fold into their tertiary structure in an aqueous environment-a cell is, after all, 60% water. The chemical properties of the various R-groups (sidechains) of the amino acids within the protein chain will influence the way that the protein folds in its environment.
