The development of methods to monitor protein dynamics in cells together with the discovery of specific and general lysosomal inhibitors have resulted in the identification of different classes of cellular proteins, long- and short-lived, and the findings of the differential effects of the inhibitors on these groups.

Biochemistry is the science of life. All our life processes - walking, talking, moving, feeding - are essentially chemical reactions. So biochemistry is actually the chemistry of life, and it's supremely interesting.
