Ionic bonds in macromolecules
WebIonic bonds are formed between ions with opposite charges. For instance, positively charged sodium ions and negatively charged chloride ions bond together to make … 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.
