Biological buffers are inert and have short-term effects on the system under investigation, both of which are distinct advantage over inorganic substances and weak organic acids that were used in the past. Most biological buffers in use today are N-substituted taurine or glycine buffers, which meet most of the requirements that biological buffers have to fulfill. Buffer systems are usually used for experiments to enable direct comparison of results.
