Ionic bonds salt bridges

Web1 dag geleden · A. Ionic Bonds (salt bridges) Ionic bonds are formed as atoms of amino acids bearing opposite electrical charges are juxtaposed. Ionic bonds can be important to protein structure because they are potent electrostatic attractions. In the hydrophobic interior of proteins, ionic bonds can even approach the strength of covalent bonds. Web1 jul. 2014 · Salt bridges are ionic bonds between positively and negatively charged side chains of amino acids. An example is the attraction between a -COO- ion of lysine and an -NH+ 3 ion of aspartic acid. Increasing the pH by adding a base converts the -NH+ 3 ion to a neutral -NH2 group.
