Solutions with a high concentration of solute at a given pK a tend to maintain pH at that pK a value, buffering the solution against pH changes. Since they work and play well with water, we call these molecules hydrophilic, which means water-loving. Another important glucose-based polysaccharide is cellulose, which is formed in plant cells. Multiple proteins can associate into quaternary structures. E A solution with 0.
